The spotted lanternfly (Lycorma delicatula) is a planthopper indigenous to parts of China and Vietnam. It has spread invasively to Japan, South Korea, and the United States, where it is often referred to by the acronym "SLF". [2] Its preferred host is the tree of heaven ( Ailanthus altissima ), but it also feeds on other trees, and on crops including soybean, grapes, stone fruits, and Malus spp. [3] In its native habitat, L. delicatula populations are regulated by parasitic wasps.

Contents

The spotted lanternfly's life cycle is often centered on its preferred host, Ailanthus altissima, but L. delicatula can associate with more than 173 plants. Early life stages (instars) of the spotted lanternfly are characterized by spotted black and white nymphs that develop a red pigmentation and wings as they mature. Early life instars have a large host range that narrows with maturation. Adult spotted lanternflies have a black head, grey wings, and red hind wings. Adults do not have any specialized feeding associations with herbaceous plants but cause extensive damage to crops and ornamental plants. The piercing wounds caused by their mouthparts and the honeydew waste they excrete are harmful to the health of host plants. They feed on the sap of host plants, including the tree of heaven, an invasive tree. [4] The damage to native hardwood forests which was feared at the outset did not come to pass. [5] Unlike some insects, the spotted lanternfly does not pose direct danger to humans through biting or stinging. [4] Spotted lanternflies lay egg masses containing 30–50 eggs, often covered with a grayish mud-like coating. [6]

The species was introduced into South Korea in 2006 and Japan in 2009, and has since been considered a pest. In September 2014, L. delicatula was first recorded in the United States, and as of 2022, it is considered an invasive species in much of the Northeastern United States and is rapidly spreading south and west. [7] L. delicatula's egg masses are the primary vector of spread, with Ailanthus altissima populations seen as a risk factor for further infestation globally. Ongoing pest control efforts have sought to limit population growth, due to the threat L. delicatula poses to global agricultural industries. Parts of the United States are undergoing massive pest control efforts to cull the spotted lanternfly's population. However, this process indirectly harms other species. [8]

Taxonomy and discovery

Lycorma delicatula is a species in the genus Lycorma , in the planthopper family Fulgoridae, subfamily Aphaeninae. Species within this genus are found in Asia. [9] L. delicatula was originally described by Adam White in 1845 as Aphaena delicatula, and the first scientific collections were made outside of Nanking, China. [10] White described the species as similar to Aphaena variegata, another planthopper species native to Asia, and referenced prior descriptions by George Tradescant Lay in his initial classification of the spotted lanternfly. [10]

In 1863, the species was reclassified by Carl Stål as Lycorma delicatula delicatula, with two additional subspecies described: Lycorma delicatula jole and Lycorma delicatula operosa. [11] [12] Taxonomic classification places two other species ( L. imperialis and L. meliae ) as closely related to the spotted lanternfly. [13] [ full citation needed ] [14] The name Lycorma delicatula derives from lyc/lyco, meaning "lamp" and delicatula, meaning "luxurious". [15] L. delicatula is also referred to as the spot clothing wax cicada ("chu-ki" or "banyi-la-chan" in Chinese) and the Chinese blistering cicada ("ggot-mae-mi" 꽃매미 in Korean). [16] [17]

In 2019, the genome of L. delicatula was fully sequenced, [18] with Aphaena amabilis , and Pyrops candelaria both being classified as close relatives. [19]

Description

Adult L. delicatula measure about 25 millimetres (1 in) long and 12 millimetres (1⁄2 in) wide. Adult lanternflies have a black head and gray-brown forewings adorned with black spots. [20] White's original account identified L. delicatula as having a minimum of 20 black spots, with six spots located on the anterior margin of the forewings. [10]

When resting, the crimson hind wings are partially visible through the semi-translucent forewings, giving the lanternfly a red cast. Neatly spaced black rectangular markings color the tips of the forewings in a pattern sometimes likened to brick and mortar. In flight, the spotted lanternfly displays red hind wings with black spots on the proximal third, a white wedge in the middle of the wing, and a solid black wing tip. The abdomen is yellowish with black and white bands on the top and bottom. [20] L. delicatula displays orange, bulbous antennae covered in needle-like tips. [21] The spotted lanternfly is sexually dimorphic. Females have a set of red valvifers at the distal end of the abdomen, which males lack. When gravid (mated), the females' abdomens swell to the point where they have difficulty moving. [22] Adult females, when measured from head to wing tip, have a body length of 20 to 27 millimetres (13⁄16 to 1+1⁄16 in) while males are a smaller size, between 21 and 22 millimetres (53⁄64 and 55⁄64 in). Females also have longer legs as compared to those of their male counterparts. [23]

The lanternfly is a planthopper, and uses its wings to assist these jumps rather than making sustained flights. [24] The spotted lanternfly will perform a number of "successive collisions" upon jumping, employing both passive and active righting as it falls. This bouncing provides nymphs, and to a lesser extent adults, multiple opportunities to repeatedly attempt righting themselves following a jump. Additionally, the spotted lanternfly will also perform aerial reorientation and terrestrial righting as means to right itself, collectively giving the spotted lanternfly the ability to land on a variety of surfaces and spread rapidly through an environment. [25]

Host associations

Ailanthus altissima is a tree native to China but is invasive to many other areas worldwide. It is considered to be the key host for L. delicatula and plays an important role in the lanternfly life cycle. [26] [27] This tree is the preferred host at all documented locations where the lanternfly and A. altissima co-occur. [28] The spotted lanternfly has a host range of over 173 plant species worldwide, including grape vines, fruit trees, ornamental trees, and woody trees, including apple trees and several Rosaceae with stone fruits. [29] Depending on the life stage of L. delicatula is in, it may prefer other hosts, such as Juglans nigra, instead of A. altissima. [30]

The spotted lanternfly has feeding behavior associated with 103 plant taxa, accounting for 33 families and 17  orders, with 56 of these plants occurring in the United States. [3] This host range includes many agricultural crops – most significantly soybean (Glycine max) [3] – and common forest plants, as the nymphs are known to associate with other plants beyond A. altissima. [28] The lanternfly has also been recorded causing serious damage on at least 12 ornamental plants such as Parthenocissus quinquefolia , Phellodendron amurense , and Toona sinensis . In the United States, high populations are seen infesting common forest trees, such as maple, birch, and walnut; in Pennsylvania alone, L. delicatula has been found on more than 20 newly recorded host species of woody plants. [28]

L. delicatula feeds on woody and nonwoody plants, piercing the phloem tissue of foliage and stems with specialized mouthparts, and sucking the sap; [29] it does not eat the fruit or the leaves per se. [24] The sugary waste fluid they produce can coat leaves and stems, which encourages mold growth and can impede photosynthesis. [31] Lycorma delicatula feed on sap from the trunk or branches of their host plants; because they can appear in such large numbers on a single plant, they can directly cause substantial damage to, and effectively kill parts or the whole of the host. [32]

L. delicatula also indirectly affects the health and productivity of their hosts and nearby plants through the production of large amounts of honeydew, the lanternfly's sugary secretions of excess waste and sap, as well as by leaving feeding scars in the host plant's branches that continue to drip sap. [33] The accumulation of this thick honeydew and tree sap on leaves below the host plant canopy can lower plants' photosynthetic potential and affect their health; this reduction is even more pronounced by the possible growth of molds over the sugary compound, which further limits light available to affected plants. The accumulation of sap and honeydew also attracts many species of ants, bees, and wasps; infestations of L. delicatula may thus be hinted at by unusual amounts of molds or stinging insects around specific plants. [34] Bees often use spotted lanternfly honeydew to produce late-season honey. [35] [36]

Nymphs typically hatch from their egg cases starting in late April or early May, marking the beginning of the lanternfly's developmental stages. A nymph passes through several immature stages, all of which are wingless. In the first instar, it is black with white spots. Later instars have red patches in addition to the white spots. The final nymphal instar has red wing pads and a red upper body, before molting to the adult form, with a black head and grayish wings with black spots. [29] Nymphs hop or crawl to search for plants on which to feed. [20] Young nymphs (first through third instars) appear to have a wider host range early on, which narrows as they grow older. [29] [37] Though lanternflies have been recorded feeding on several herbaceous plants, this is most likely due to early-instar nymphs climbing or falling onto these plants; late-instar nymphs and adult lanternflies have no reliable association with herbaceous plants. [28]

As early as July, adults can be seen, and they mate and lay eggs from late September through the onset of winter. [29] During mating periods, spotted lanternflies will perform migratory flights. During these migrations, adult L. delicatula will perform a brief courtship and copulation which will last for up to 4 hours. [38] In their native Indomalayan habitat, they lay their eggs preferably on tree of heaven (A. altissima), which is a poisonous invasive species that was introduced to North America. This host choice is thought to have evolved as a mechanism of protection from natural enemies. [29]

The spotted lanternfly has been found to be capable of reproducing using hosts other than A. altissima, but they generally fail to reach high populations unless A. altissima is present. [39] Many hypotheses are given as to why L. delicatula may have preferences for feeding on certain plants. Two examples of possible factors being investigated are the contribution of the overall sugar composition in the plant [40] and the presence of toxic chemicals. [37] The lanternfly lays eggs upon any smooth-trunked tree, stone, or vertical smooth surface, including man-made items such as vehicles, yard furniture, farm equipment, or other items stored outside. [20]

The egg masses contain 30–50 eggs [41] covered in a yellowish-brown, waxy deposit, often referred to as an egg case. [29] L. delicatula eggs undergo diapause during embryonic development, requiring two weeks of warm temperatures following winter before hatching is induced. Eggs overwintered for five months or longer demonstrate higher hatch rates and more synchronous hatching, suggesting that cold temperatures increase overall egg survival rates. [38] The majority of adults die off by the end of December. [29] [22]

Testing has been done to determine how overwintering affects the eggs of this species. The highest temperature that will still kill eggs was estimated by South Korean researchers to be between −12.7 and −3.4 °C (9.1 and 25.9 °F) on the basis of mean daily temperatures during their winter of 2009–2010. [42] This estimate contrasts with eggs having survived the much colder winter 2013–2014 temperatures in Pennsylvania, United States. [43] Another study done at Rutgers University suggested that −25 °C (−13 °F) is about the temperature at which no eggs are hatched, while −15 °C (5 °F) still had limited hatching, depending upon how long they were chilled and where they were kept. [44]

Distribution

Native range

The spotted lanternfly is native to subtropical regions of Southeast Asia. [37] [31] Fossil evidence indicates L. delicatula evolved between 55 and 51.6 myr, during the Ypresian Era. [45] [46] Phylogenomic analysis has shown that L. delicatula originally evolved in southwest China, eventually diverging into six phylogeographic lineages. One of these lineages then moved northward, following the Yangtze River during the late Pleistocene Era. [47]

In the 1930s, L. delicatula was known to inhabit the Northern Provinces of Shanxi, Shandong and Hebei. Since then, it has expanded its range to include Anhui, Beijing, Guangdong, Henan, Jiangsu, Sichuan, Yunnan and Zhejiang. In traditional Chinese medicine, the spotted lanternfly is believed to be poisonous, and has been used since the 1100s for topical relief from swelling. [29] [21] L. delicatula has also been reported in Taiwan, Vietnam, and India, but ongoing research has yet to conclude whether the species is native to these regions. [48]

Accidental introduction

Lycorma delicatula normally uses A. altissima for feeding and laying eggs, but if it is not present, the insect can lay its eggs on any stationary object, natural or man-made, and feeds on a wide variety of plants. Eggs can easily be moved from place to place without being noticed, giving them an easy way to spread to new areas. Its initial introduction to the United States is believed to have been through this pathway, hitchhiking on an object imported from Asia into Pennsylvania. Adults of L. delicatula jump around the area to find new host plants. As nymphs, they feed on whatever host plant the egg was laid on before moving to another in the area. L. delicatula is capable of surviving and completing its life cycle in environments without its preferred host, A. altissima, albeit with greatly reduced fitness. [39]

In South Korea

In 2006, the spotted lanternfly was introduced in Korea, and has been considered a pest since about 2007. It has since expanded its host range, attacking at least 65 plant species, uninhibited by natural predators. [24] The distribution of L. delicatula has since been predicted using a modeling approach, which showed that this pest has the potential to occur in the majority of South Korea. [49]

A correlation seems to exist between the widespread distribution of A. altissima and overall damage to grapevines. [28] The tree is commonly found growing on the peripheries of Korean vineyards and L. delicatula has been documented as a pest to grapevines, leading to a decline in the total number and overall quality of the harvested grapes. No quantitative data has been published supporting this correlation, but it has been widely hypothesized. [50] [28]

In Japan

In 2009, Japan reported its first confirmed presence of the spotted lanternfly, in Komatsu city (Ishikawa Prefecture). In 2013, it was confirmed to have spread into the Fukui Prefecture. [14] Researchers have estimated that the spotted lanternfly may have been entering the country sporadically since the 1930s, but only established a reproducing population around the beginning of the twenty-first century. Specimens found in Japan are genetically identical to populations in Beijing, Tianjin, Qingdao, and Shanghai, China. [48]

In the United States

On 29 September 2014, the Pennsylvania Department of Agriculture (PDA) and the Pennsylvania Game Commission first confirmed the presence of the spotted lanternfly in Berks County, northwest of Philadelphia. [32] [51] Based on its host affinities, it presents a threat to the state's grape, fruit tree, and logging industries. The greatest risk of spread was seen in transportation of materials containing egg masses laid on smooth bark, stone, and other vertical surfaces. [20]

The Pennsylvania Department of Agriculture banned the transport of items that could harbor the egg masses, including firewood, lawn mowers, outdoor chairs, trucks, and recreational vehicles from seven municipalities on 1 November 2014. [20] Considering the old egg masses that were found, it was estimated that the spotted lanternfly might have been in the United States since at least 2012 (thought to have arrived as egg masses on a stone shipment in 2012), and had survived the unusually cold 2013–2014 winter. [43] By March 2021, lanternflies had been found in 34 of the 67 counties in Pennsylvania. [52] [53]

In 2019, Pennsylvania State University estimated statewide costs of the spotted lanternfly to be $99 million in agricultural losses, and $236 million to the forestry industry, annually. Models of the spotted lanternfly's spread projected an annual loss of $554 million, with an additional loss of 4,987 jobs, should it continue to spread to the entirety of Pennsylvania. [54] A national working group led by the U.S. Department of Agriculture, consisting of Penn State Researchers and USDA scientists, was organized "to determine what is known about the lanternfly and what research is needed, including DNA analysis to pinpoint where the infestation originated." [24]

Other states began seeing spotted lanternflies as soon as 2018, and by 2021, they were also confirmed to be established in at least parts of Connecticut, [55] Maryland, [55] Massachusetts, [56] Delaware, [57] New Jersey, [58] New York, [59] Ohio, [60] Indiana, [61] Virginia, [62] and West Virginia, [55] with several of these states issuing quarantine orders. [55] In 2022, the species was confirmed to be present in North Carolina, [63] Michigan [64] [65] and Rhode Island,. [66] In late September 2023, the state government of Tennessee confirmed the detection of a spotted lanternfly (SLF) in its Davidson County, making Tennessee the 16th state to detect the spotted lanternfly. [67]

In October 2024, their presence was reported in Northern Kentucky, especially in Covington. [68]

A large potential range exists for the spotted lanternfly to become established in almost all of the eastern part of the country, as well as critical wine- and hop-growing valleys of the Pacific coastal states. [69]

Dead spotted lanternfly specimens have been reported in Kansas, [70] [71] Oregon [72] and California, [73] although no live sightings have been reported from these states as of September 2023. The discoveries of dead specimens have increased concerns for possible accidental introduction of the insect to yet more states where they can potentially become established. [74]

In Canada

Canadian Food Inspection Agency has identified a risk of the SLF entering the country and has previously intercepted adult lanternflies traveling to Ontario in shipping crates. The primary concern is the potential damage the lanternflies could cause to the wine, fruit, and vegetable industries. [75] [69] The Canadian government and agricultural industries are concerned about maintaining quarantine and have expressed hope that quarantine efforts in the United States are successful. [75] Although most of Canada is an unsuitable habitat for L. delicatula, southwestern Ontario and southerly parts of other provinces are modeled to have low suitability for inhabitation. [69] L. delicatula has been theorized to be capable of maintaining a small population in the region although no specimens have yet been discovered. [69]

Later, in September 2024, lanternflies were found in Ontario. [76]

In Europe

The European and Mediterranean Plant Protection Organization classifies L. delicatula as an A1 pest and anticipates it becoming invasive in Europe. [77] CLIMEX modeling of potential habitats for L. delicatula has found that the United Kingdom, France, Belgium, Switzerland, Spain, and Italy may be capable of supporting small L. delicatula populations. [78] Risk analysis of the spotted lanternfly to become established in Europe has been classified as a moderate to high risk, predominately due to the pervasiveness of A. altissima. [28] L. delicatula was observed via INaturalist in Madrid, Spain on July 17, 2024. [79]

In Australia

Modeling for the life cycle of the spotted lanternfly in Australia has found that development and survival may vary throughout the country, should the spotted lanternfly be introduced. Australia's southwest coastal regions are estimated to have a high viability for the spotted lanternfly but Australian Great Dividing Range and Tasmania were found to have the lowest suitability. Both the pervasiveness of A. altissima and the lack of consistent freezing seasons are considered risk factors in L. delicatula establishing populations in the country. [80]

Possible pest control

Pest control measures and guidelines have been issued by the Pennsylvania Department of Agriculture and its Penn State Extension. These guidelines include killing L. delicatula eggs between the months of October and May by scraping them off surfaces, "double bag them and throw them in the garbage." [20] People can scrape the eggs directly into plastic bags containing alcohol and/or hand sanitizer to kill them. The PDA has recommended removal of preferred spotted lanternfly hosts, such as tree of heaven ( Ailanthus altissima ), saving only male trees to use as "trap" trees, since the spotted lanternfly is attracted to its preferred hosts. [81] The remaining male "trap trees" should be wrapped with sticky bands starting in early spring to catch any nymphs. Wildlife experts have warned to cover the sticky bands on trees with chicken wire or another similar wire after many reports of other animals (e.g. birds) becoming trapped on them, resulting in injury and/or death. [82]

As of 2020, the PDA recommended several different pesticides to treat infestations, including insecticidal soaps, neem oil, pyrethrins, and essential oils, as well as bifenthrin, carbaryl, dinotefuran as bark spray, imidacloprid, spinosad, tebuconazole, and zeta-cypermethrin. [81] Infested trees can be treated with systemic pesticides from June to August. The PDA recommends tree injection and bark sprays, applied by professional applicators, and soil drench and foliar sprays, which can be applied by homeowners. [81]

In Pennsylvania and Korea, use of brown sticky traps has been effective at capturing nymphs, though adults may be strong enough to escape the adhesive. [28] [83] The spotted lanternfly is known to avoid changes in tree texture and obstacles along the tree trunk, and inward facing traps have shown the greatest efficacy with minimized ecological impact. [84] L. delicatula has been found to be attracted to certain kairomones released by their host plants, and adults and second- to fourth-instar nymphs are also attracted to spearmint oil. Such chemicals (like methyl salicylate) may be used to lure them into sticky traps to augment this pest control method. [85]

Researchers using infrared thermography have found that the spotted lanternfly emits long-wavelength infrared (8–14 μm) light during active feeding and rapid hemolymph circulation, indicating a means of early detection. [86] Trained dogs are capable of detecting winterized egg masses. [87]

As of 2013, researchers are investigating another method of controlling lanternfly populations through reduction of Ailanthus altissima populations; the use of a fungal pathogen, Verticillium nonalfalfae , has been found to effectively kill the invasive trees by causing vascular wilt. [88] It is thought that lanternflies, which feed on this host plant by piercing and sucking the sap from its vasculature, may be able to "aid" in the ongoing removal of A. altissima by functioning as a vector for the V. nonalfalfae pathogen between different individuals of the insects' preferred host. Researchers have not yet found this to be an effective method, and more research is needed to confirm if this is possible in field settings with V. nonalfalfae or other pathogens. [89]

Four species of fungal entomopathogens native to the United States have been identified to cause co-epizootics in the spotted lanternfly. [90] Beauveria bassiana, Batkoa major , Metarhizium pemphigi and Ophiocordyceps delicatula (in the family Entomophthoraceae) have been found to parasitize and kill the spotted lanternfly, with Beauveria bassiana having also shown an ability to kill spotted lanternflies in biopesticide trials. [90] [91] [92]

A few natural predators have been identified in the lanternfly's native habitat in China, but are not yet used in biocontrol. Dryinus sinicus , a dryinidae wasp, and Ooencyrtus kuvanae , a chalcid wasp, have been found to parasitize spotted lanternfly eggs and nymphs. [93] [94] Ooencyrtus kuvanae was previously introduced into the United States in 1908 for population control of Lymantria dispar dispar and was first documented to parasitize spotted lanternfly egg masses in 2017. [93] Another biocontrol predator being tested is the eupelmid wasp Anastatus orientalis , due to its high rates of parasitism of eggs. This wasp is under investigation in South Korea [95] and in the United States, where it is being evaluated under quarantine until researchers are certain it will not become an invasive species and attack other insects. [96]

Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 described species.

Leafhopper is the common name for any species from the family Cicadellidae. These minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees. Their hind legs are modified for jumping, and are covered with hairs that facilitate the spreading of a secretion over their bodies that acts as a water repellent and carrier of pheromones. They undergo a partial metamorphosis, and have various host associations, varying from very generalized to very specific. Some species have a cosmopolitan distribution, or occur throughout the temperate and tropical regions. Some are pests or vectors of plant viruses and phytoplasmas. The family is distributed all over the world, and constitutes the second-largest hemipteran family, with at least 20,000 described species.

A planthopper is any insect in the infraorder Fulgoromorpha, in the suborder Auchenorrhyncha, a group exceeding 12,500 described species worldwide. The name comes from their remarkable resemblance to leaves and other plants of their environment and that they often "hop" for quick transportation in a similar way to that of grasshoppers. However, planthoppers generally walk very slowly. Distributed worldwide, all members of this group are plant-feeders, though few are considered pests. Fulgoromorphs are most reliably distinguished from the other Auchenorrhyncha by two features; the bifurcate (Y-shaped) anal vein in the forewing, and the thickened, three-segmented antennae, with a generally round or egg-shaped second segment (pedicel) that bears a fine filamentous arista.

Paracoccus marginatus, commonly known as the papaya mealybug, is a small sap-sucking insect in the mealybug family, Pseudococcidae. It is found on a number of different hosts, including economically important tropical fruit trees and various ornamental plants.

<i>Planococcus citri</i> Species of true bug

Planococcus citri, commonly known as the citrus mealybug, is a species of mealybugs native to Asia. It has been introduced to the rest of the world, including Europe, the Americas, and Oceania, as an agricultural pest. It is associated with citrus, but it attacks a wide range of crop plants, ornamental plants, and wild flora.

<i>Lycorma</i> Genus of planthoppers

Lycorma is a genus of planthoppers native to Asia. The first species within the genus was described by Frederick William Hope in 1843 and the genus was formally established by Carl Stål in 1863.

<i>Aleurocanthus spiniferus</i> Species of true bug

Aleurocanthus spiniferus, the citrus spiny whitefly, is an insect native to Asia. It is considered an invasive pest, notably affecting citrus and tea plants. They are part of the whitefly family.

Anastatus orientalis is a species of parasitic wasp which preys on Lycorma lanternfly eggs. Females live significantly longer than males, over ten weeks compared to the male lifespan of three weeks.

<i>Planococcus ficus</i> Species of mealybug

Planococcus ficus, commonly known as the vine mealybug, is a species of mealybug, belonging to the family Pseudococcidae, native to tropical and subtropical regions. The vine mealybug is found in Europe, Northern Africa, Southern Africa, the Americas, and the Middle East. The vine mealybug is invasive to weedy plants in many different regions of the world.

Batkoa major is a naturally occurring fungus that infects insects.

<i>Lycorma imperialis</i> Species of insect

Lycorma imperialis is a planthopper indigenous to parts of China and Indo-Malaysia. L. imperialis was originally discovered in 1846 by Adam White and has one recognized non-nominate subspecies, L. i. punicea. L. imperialis has undergone a number of reclassifications since its discovery and is one of four species in the genus Lycorma. L. imperialis follows a hemimetabolous life cycle and will undergo a series of nymphal stages (instars) before maturing to an adult.

<i>Ooencyrtus kuvanae</i> Species of chalcid wasp

Ooencyrtus kuvanae is a species of chalcid wasp. It was introduced to North America in 1908 to control Lymantria moths. In North America, it has become an active parasitoid of the invasive spotted lanternfly.

<i>Lycorma meliae</i> Species of insect

Lycorma meliae is a planthopper species endemic to Taiwan, with multiple, dramatically different color morphs depending on the life stage. The species was described by Masayo Kato in Taiwan in 1929, and is the only member of its genus confirmed to be native to the island. In 1929, a specimen of L. meliae was originally described as a separate species, L. olivacea, also by Kato. These two taxon names were declared synonymous in 2023. L. meliae undergoes four instar stages before achieving adulthood and generally only survive until the winter.

<i>Erasmoneura vulnerata</i> Species of leafhopper

Erasmoneura vulnerata is a species of leafhopper native to North America. The species was found to be in Europe in 2004 where it causes significant economic damage to grapevine yards. E. vulnerata is commonly found on wild and cultivated grapes from both continents. Its Latin name translates to "wounded Erasmoneura" from its original description.
