Marpesia berania (Hewitson 1852) | |
Marpesia berania, the amber daggerwing, is a butterfly in the family Nymphalidae. The species was first described by William Chapman Hewitson in 1852. They are a brightly colored, Neotropical butterfly with a unique wing shape, found in Central and northern South America. The amber daggerwing exhibits several interesting characteristics varying from their unusual behavior to their physical traits that make them so distinct.
The genus name Marpesia is derived from Marpess, the wife of Idas, a mortal who decided to go against Apollo when he carried off Marpessa /ˌmɑːrˈpɛsə/ (Ancient Greek: Μάρπησσα). [1] The derivation of berania is not known.
The distribution range for Marpesia berania is largely in the Neotropical realm, branching out to Central America and northern South America. Countries inhabited by this species include Mexico, Honduras, Costa Rica, Brazil, Peru, Colombia and Bolivia. [2] These butterflies are considered to be a commonly found species in Honduras and in Peru. M. berania is found in the tropical rainforests and lowlands of these regions. [3] They are considered to be closely allied or related to the Cyrestis (mapwing butterflies) and Chersonesia (maplet butterflies). [4]
M. berania is seen most in January, February, and March. [5] In 2020, 3-8 individuals were spotted each of these three months, with the most individuals (8) occurring in March. In contrast, the butterflies appeared absent from April to October 2020, with only one individual spotted in May, August, and October. [5]
Marpesia butterflies lay individual eggs on the leaves of trees and shrubs in the family Moraceae, which include shrubs of the genus Ficus and Brosimum alicastrum . The eggs are white or yellowish. [4]
Development to the larval stage can be variant in Marpesia species, especially in M. berania. If the following season post-egg laying is rainy or has subsequent heavy rains, this can influence the growth rate and development of the butterfly. Heavy rain is known to kill early larvae, which are highly susceptible to drowning and molding. [6] [7] If the M. berania larvae survives the harsh conditions, they grow to full size within 6-8 days, developing a colorful pattern marked with a yellow body with blue-green stripes running longitudinally from head to tail. [4] The head of the larvae has two prong-like antennas that protrude vertically from the head, giving it the appearance of horns. The larvae feed during the day and then spend their nights resting on the tops of leaves. [4] Pupae are pale, with dark spots or blotches. [4]
The longevity of M. berania is exceptional compared to other tropical butterflies. It was found that 9.0% of 43.9 surviving marked butterflies were found living after 157 days. [2] This is in comparison to two species of Heliconius , Heliconius erato and Heliconius erato hydrara . H. erato was found to live an average 3.5 months when curated in insectaries, [8] and 100 days for H. erato hydrara when observed in the natural population in Trinidad. [9]
M. berania is found in tropical rain forests and along waterways and roads in the lowlands of Central America. [2] They can be found most commonly at elevations below 1000 meters, but have been found in locations up to 1800 meters above sea level. [4] Typically, M. berania is seen during the wet seasons of Central and South America, from early March to mid-August. [2] [4] As elaborated on in the Life ecology section, the amber daggerwing roosts in clumps of leaves found on small trees. [3] The trees they make their homes in can usually be found on riverbanks, in clearings, and other semi-open areas. [4]
Marpesia berania is highly impacted by habitat loss, fragmentation, and degradation from anthropogenic causes. Since the rainforest is one of their habitats, this species is affected by deforestation in the region. [3]
Marpesia berania exhibit a behavior called communal or group roosting. [2] These butterflies have been recorded to have a typical nocturnal roosting site on the underside of the leaves of rubiaceous trees or other small trees. Group roosts can include up to 60 individuals, and have equal numbers of male and female individuals. Interestingly, while roosts are nocturnal, female M. berania return earlier in the day than their male counterparts. [2] This behavior puts them in the middle of the roosting site, progressively surrounded by males upon their return.
M. berania is one of the few butterfly species that sleep together in groups on leaves. This is for protection and to escape any potential dangers as a group. If one butterfly has been disturbed, it will respond by opening its wings, touching its neighbors' wings, creating a domino effect to alert others of the potential danger. [10] Another behavior that is noted is when the temperatures are too high, they will reposition in a way to minimize the surface area of exposure to the sun.
Marpesia berania males engage in mud-puddling and are observed singly or in small groups of up to six at riverbanks or puddles, consuming moisture. The females rarely leave the forest. [4] A common behavior observed only at high temperatures for both males and females is that they will erect their wings when feeding or are at rest on foliage, but M. berania typically bask in the sun or in open space with their wings outspread. [1] [2]
Both sexes have been shown to have equal life expectancy and reproduction so that next generations can be alleviated or remain unaffected by abiotic factors via recruitment. [2] As both sexes have equal life expectancy, the adult sex ratio of M. berania is 1:1. J. Merritt Emlen speculates that selection would reduce the butterflies' ability to reproduce with age. [11] Successful reproduction and low young age mortality can result in greater longevity and more energy resourced towards increasing immediate reproductive output. [12]
Oviposited or larval mortality is not sourced at this time. Adult mortality is speculated to be caused by bird predation, considering the broad area covered by roosting groups. [2] Since M. berania is known to have a high longevity, any senescence effect on mortality is not supported as both sexes have been studied to live out equally long life spans. They are also strong and evasive flyers, which may contribute to their ability to escape potential predation or attacks.
Marpesia berania can be identified primarily by its wings. These butterflies are sexually dimorphic, meaning that males and females look different from each other. This difference is easiest to detect by looking at the surface of the butterfly's wings, as both sexes have a pearly underside color. Male M. berania butterflies are bright orange with vertical dark brown striping on the surface of their wings, while, female M. berania are less vibrant, appearing more of a brownish orange. [2] Both sexes have a telltale drastic point at the bottom ends of their wings, lending to their designation as a daggerwing butterfly. The same point is also seen in other Marpesia species.
M. berania have similar wing shapes to swallowtails, mimicking the sharp wing structure present in both. The difference between the two species is that M. berania has four functional legs rather than six. Unlike most other butterflies, the front two legs of this species are curved inwards towards the body, which is a characteristic found in the family Nymphalidae. Another distinguishing feature is that the antennae on Marpesia species are straight instead of curved at the end like most Papilionoidea butterflies. [4]
Two subspecies are also recognized: [13]
Butterflies are winged insects from the lepidopteran suborder Rhopalocera, characterized by large, often brightly coloured wings that often fold together when at rest, and a conspicuous, fluttering flight. The group comprises the superfamilies Hedyloidea and Papilionoidea. The oldest butterfly fossils have been dated to the Paleocene, about 56 million years ago, though they likely originated in the Late Cretaceous, about 101 million years ago.
The Gulf fritillary or passion butterfly is a bright orange butterfly in the subfamily Heliconiinae of the family Nymphalidae. That subfamily was formerly set apart as a separate family, the Heliconiidae. The Heliconiinae are "longwing butterflies", which have long, narrow wings compared to other butterflies.
The telephone-pole beetle is a beetle native to the eastern United States and the only living representative of the otherwise extinct family Micromalthidae. Larvae of the beetle live in decaying wood and can be pests to wooden structures, lending them their common name, the 'telephone-pole beetle.'
Papilio polyxenes, the (eastern) black swallowtail, American swallowtail or parsnip swallowtail, is a butterfly found throughout much of North America. An extremely similar-appearing species, Papilio joanae, occurs in the Ozark Mountains region, but it appears to be closely related to Papilio machaon, rather than P. polyxenes. The species is named after the figure in Greek mythology, Polyxena, who was the youngest daughter of King Priam of Troy. Its caterpillar is called the parsley worm because the caterpillar feeds on parsley.
The small heath is a butterfly species belonging to the family Nymphalidae, classified within the subfamily Satyrinae. It is the smallest butterfly in this subfamily. The small heath is diurnal and flies with a noticeable fluttering flight pattern near the ground. It rests with closed wings when not in flight. It is widespread in colonies throughout the grasslands of Eurasia and north-western Africa, preferring drier habitats than other Coenonympha, such as salt marshes, alpine meadows, wetlands, and grasslands near water. However, habitat loss caused by human activities has led to a decline in populations in some locations.
Heliconius charithonia, the zebra longwing or zebra heliconian, is a species of butterfly belonging to the subfamily Heliconiinae of the family Nymphalidae. It was first described by Carl Linnaeus in his 1767 12th edition of Systema Naturae. The boldly striped black and white wing pattern is aposematic, warning off predators. It is the state butterfly of Florida.
Dryas iulia, commonly called the Julia butterfly, Julia heliconian, the flame, or flambeau, is a species of brush-footed butterfly. The sole representative of its genus Dryas, it is native from Brazil to southern Texas and Florida, and in summer can sometimes be found as far north as eastern Nebraska. Over 15 subspecies have been described.
The grayling or rock grayling is a species in the brush-footed butterfly family Nymphalidae. Although found all over Europe, the grayling mostly inhabits coastal areas, with inland populations declining significantly in recent years. The grayling lives in dry and warm habitats with easy access to the sun, which helps them with body temperature regulation.
Limenitis arthemis, the red-spotted purple or white admiral, is a North American butterfly species in the cosmopolitan genus Limenitis. It has been studied for its evolution of mimicry, and for the several stable hybrid wing patterns within this nominal species; it is one of the most dramatic examples of hybridization between non-mimetic and mimetic populations.
Heliconius erato, or the red postman, is one of about 40 neotropical species of butterfly belonging to the genus Heliconius. It is also commonly known as the small postman, the red passion flower butterfly, or the crimson-patched longwing. It was described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
Heliconius cydno, the cydno longwing, is a nymphalid butterfly that ranges from Mexico to northern South America. It is typically found in the forest understory and deposits its eggs on a variety of plants of the genus Passiflora. It is a member of the Heliconiinae subfamily of Central and South America, and it is the only heliconiine that can be considered oligophagous. H. cydno is also characterized by hybridization and Müllerian mimicry. Wing coloration plays a key role in mate choice and has further implications in regards to sympatric speciation. Macrolide scent gland extracts and wing-clicking behavior further characterize this species.
The Honduran white bat, also called the Caribbean white tent-making bat, is a species of bat in the family Phyllostomatidae. It is the only member of the genus Ectophylla. The genus and the species were both scientifically described for the first time in 1892. It has distinctive, entirely white fur, which is only found in six of the roughly 1,300 known species of bat. It constructs "tents" out of understory plant leaves by strategically cutting the leaf ribs with its teeth; it roosts in these tents during the day. It is a specialist frugivore, consuming almost exclusively the fruits of one species of fig. Females can likely become pregnant twice per year, giving birth to one offspring at a time.
Anartia fatima, the banded peacock, is a butterfly in the family Nymphalidae. It is commonly found in south Texas, Mexico, and Central America but most studied in Costa Rica. This butterfly prefers subtropical climates and moist areas, such as near rivers. It spends much of its time in second-growth woodlands.
Heliconius comprises a colorful and widespread genus of brush-footed butterflies commonly known as the longwings or heliconians. This genus is distributed throughout the tropical and subtropical regions of the New World, from South America as far north as the southern United States. The larvae of these butterflies eat passion flower vines (Passifloraceae). Adults exhibit bright wing color patterns which signal their distastefulness to potential predators.
Papilio homerus, commonly known as the Homerus swallowtail or Jamaican swallowtail, is the largest butterfly species in the Western Hemisphere. The species is endangered and faces a potentially bleak future. Only two small populations of the Homerus swallowtail remain in a fraction of their original environment. It is endemic to Jamaica where the butterfly simultaneously serves as an icon of national pride and a need for conservation efforts. Over the past half century, the Jamaican swallowtail has been featured on various postal stamps and the Jamaican $1000 bill. In the face of rapid habitat destruction from human disruption and illegal collecting, the Jamaican swallowtail is listed on the Threatened Swallowtail Butterflies of the World by the International Union for Conservation of Nature and is protected under international and national level legislation.
Heliconius melpomene, the postman butterfly, common postman or simply postman, is a brightly colored, geographically variable butterfly species found throughout Central and South America. It was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. Its coloration coevolved with another member of the genus, H. erato as a warning to predators of its inedibility; this is an example of Müllerian mimicry. H. melpomene was one of the first butterfly species observed to forage for pollen, a behavior that is common in other insect groups but rare in butterflies. Because of the recent rapid evolutionary radiation of the genus Heliconius and overlapping of its habitat with other related species, H. melpomene has been the subject of extensive study on speciation and hybridization. These hybrids tend to have low fitness as they look different from the original species and no longer exhibit Müllerian mimicry.
Jalmenus evagoras, the imperial hairstreak, imperial blue, or common imperial blue, is a small, metallic blue butterfly of the family Lycaenidae. It is commonly found in eastern coastal regions of Australia. This species is notable for its unique mutualism with ants of the genus Iridomyrmex. The ants provide protection for juveniles and cues for adult mating behavior. They are compensated with food secreted from J. evagoras larvae. The ants greatly enhance the survival and reproductive success of the butterflies. J. evagoras lives and feeds on Acacia plants, so butterfly populations are localized to areas with preferred species of both host plants and ants.
Marpesia is a butterfly genus in the family Nymphalidae. The species of this genus are found in the Neotropical and Nearctic realms.
Eucheira socialis, commonly known as the Madrone butterfly is a lepidopteran that belongs to the family Pieridae. It was first described by John O. Westwood in 1834. Locally known as Mariposa del madroño or tzauhquiocuilin, it is endemic to the highlands of Mexico, and exclusively relies on the Madrone as a host-plant. The species is of considerable interest to lepidopterists due to gregarious nest-building in the larval stages, and heavily male-biased sex ratio. It takes an entire year for this adult butterfly to develop from an egg. The eggs are laid in the month of June and the adults emerge the following May–June. The adults have a black and white pattern on their wings, and the males are generally much smaller and paler than the females. The larvae do not undergo diapause and continue to feed and grow communally in the coldest months of the year. There are two subspecies of E. socialis, named E. socialis socialis and E. socialis westwoodi.
Marpesia zerynthia, the waiter daggerwing, is a species of butterfly in the family Nymphalidae. Primarily found in Mesoamerica, it can also be observed in regions slightly north and south of this area.
