Anthocharis cardamines, the orange tip, is a butterfly in the family Pieridae, which contains about 1,100 species. A. cardamines is mainly found throughout Europe and temperate Asia (Palearctic) [2] The males feature wings with a signature orange pigmentation, which is the origin of A. cardamines' common name. [3]
Males and females of this species occupy different habitats: males mostly frequent the edges of forests whereas females frequent meadows. A. cardamines feeds on most plants found within its habitat but the females selectively oviposit on young inflorescence of crucifers.
Mating is usually controlled by females as virgin females found in flight are always pursued by males immediately. [4] Females can signal different meanings to the approaching males by using their abdomen. There is evidence that mated females have an anti-aphrodisiac and that their usage of the abdomen has a closely related function in presenting these pheromones to males.
This species has been affected by changing temperatures, and its first appearance has shifted forward 17.3 days in the Spring.
The common name derives from the bright orange tips of the male's forewings. The males are a common sight in spring, flying along hedgerows and damp meadows in search of the more reclusive female which lacks the orange and is often mistaken for other species of butterfly. The undersides are mottled green and white and create a superb camouflage when settled on flowerheads such as cow parsley and garlic mustard ( Alliaria petiolata ). [3]
Males display a variation in body size, which is attributed to their host plant. Males reared on C. pratensis become the smaller of the two variants, and those reared on A. petiolata become the larger. [5]
A. cardamines can be found throughout Europe and across the Palearctic to China. [2]
The habitats of males and females differ significantly. [6] [7] Males are restricted to edges and clearings of forests for their entire lives. On rare occurrences, males will leave forest edges and enter meadows, but this is only to cross and reach another forest edge. [6] They prefer to fly in bright sunlight and avoid areas of shade in the forest. [6] Females are mainly found in open meadows and dry hillocks for a majority of their lives. [6] Females only spend short period of time in forests before re-entering nearby meadows. [6] In Armenia the species inhabits not only forests and woodlands, but also meadows, where males occur together with females. [8]
Female A. cardamines feed on the flowers listed above, in addition to all species of flowers located in the habitats where their host plants are found. They do not interrupt host plant search to find foraging habitats; instead, they visit available flowers in host plant habitats. [6]
Females will tend to only deposit eggs on crucifers if they are in bloom. [6] Furthermore, they prefer to oviposit on young inflorescences, and there have been instances of A. cardamines that refuse to deposit eggs on inflorescences that had aged. [6] If the stem of the inflorescence is not strong enough to support the weight of the female A. cardamines, they will cease egg laying. [6]
Initially, it was believed that the bright orange color of A. cardamines egg deterred further egg laying. [9] However, new studies have discovered another deterrent. To prevent other females from laying eggs on the same flowerhead, female A. cardamines will deposit a pheromone during egg laying. [9] This pheromone will deter other females from also laying an egg on that flower head. [9] Flower heads with more than one egg can still be found because the pheromone is water-soluble and relatively short-lived. [9]
When choosing host plants, female A. cardamines only lay eggs on host plants growing in the sun. Those in the shade are completely avoided, and plants partially covered in shade are only selected if the female does not have to travel through shaded areas to reach the plant. [9] Females are extremely selective for host plant size, and larger flower heads are preferred to smaller ones. Even when smaller flower heads are overly abundant, female A. cardamines will completely ignore them in search of larger flower heads. [9] Females will also ignore flower heads already containing a conspecific egg. This is because larva from the already laid eggs will hatch first and cannibalize any other present eggs. [9]
Eggs of A. cardamines are always deposited on inflorescences of crucifers. When first laid, eggs are white in colour and eventually change to orange and then brown after a few days. [6] Eggs are covered with a pheromone that deters other females from ovipositing on the same crucifer.
When hatched, the larva consumes its egg shell before eating the seed pods of its host plant. The fully grown larva leaves the food plant after its five larval instars and pupates on lower vegetation. [9] If more than one egg had been laid on the same host plant, then the larva to first hatch will cannibalize its sibling. [9] This is the major reason why Orange tip females avoid eggs laying on the same crucifer.
While the earlier stages of A. cardamines are easy to find since most individuals develop on a single plant, the pupa is very difficult to locate. [9]
In Britain, there have been patterns found relating weather and A. cardamines appearances. From data collected from 1976 to 1998, spring and summer temperatures were found to have increased by approximately 1 degree Celsius. [10] This has affected first appearance of A. cardamines, which has advanced by 17.3 days with the increasing temperature. [10] The increased temperature has also been to connected to increases in duration of flight period of A.cardamines in Britain. [10]
Corpses of A. cardamines caterpillars are often found with darkening around a wound near the tail. These injuries are consistent with damage inflicted by spiders, which are their main predators. [9]
The host plants of A. cardamines are often grazed by Muntjac deer. The deer favor plants with young flowers, which corresponds to the preferred plants of A. cardamines for egg laying. As a result, Muntjac deer are responsible for consuming up to nineteen percent of A. cardamines young through indirect predation. [9]
The result of male courting depends heavily on the location of the female when courted. Females found in flight are immediately pursued by males, and the encounter almost always results in acceptance of the male mating attempt. When males encounter females already perched on vegetation, their mating attempts are usually met by a raised abdomen. [4]
Both mated and virgin females respond to males with a raised abdomen, but the signals take different meanings. When a male encounters a mated female with a raised abdomen, it is taken as a signal of rejection, and he quickly leaves. When virgin females raise their abdomen, the signal takes on a male detention function instead of rejection. Males will continue to court a perched, virgin female with a raised abdomen until she acquiesces or flees. [4]
While a specific pheromone has not been identified in A. cardamines, since both the rejection signal and detention signal in females are visually identical scientists hypothesize that a chemical signal distinguish the two. Mated females tend to track the males with their abdomens during the courting attempt, and this is behavioral evidence that mated females have an anti-aphrodisiac, and that the raised abdomen presents the pheromone as close as possible to the male. [4]
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.
Pieris rapae is a small- to medium-sized butterfly species of the whites-and-yellows family Pieridae. It is known in Europe as the small white, in North America as the cabbage white or cabbage butterfly, on several continents as the small cabbage white, and in New Zealand as the white butterfly. The butterfly is recognizable by its white color with small black dots on its wings, and it can be distinguished from P. brassicae by its larger size and the black band at the tip of its forewings.
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.
Anthocharis belia, the Moroccan orange tip, is a butterfly of the family Pieridae. It is found in northwestern Africa. The length of the forewings is 18–20 millimetres (0.7–0.8 in).
Anthocharis midea, the falcate orangetip, is a North American butterfly that was described in 1809 by Jacob Hübner. It belongs to the family Pieridae, which is the white and sulphurs. These butterflies are mostly seen in the eastern United States, and in Texas and Oklahoma. They eat the nectar of violets and mustards. They tend to live in open, wet woods along waterways, in open swamps, and less often in dry woods and ridgetops. This species is a true springtime butterfly, being on the wing from April to May.
Anthocharis sara, the Sara Orangetip is one of three species in the Sara Orangetip complex. It is a California endemic butterfly with populations extending from Baja California into extreme southwest Oregon. The common name, Pacific Orangetip, is obsolete since its implied distribution includes two separate species.
Leptidea sinapis, or the wood white butterfly of the family Pieridae, is a small white butterfly that is mainly found in England, Ireland, and Northern Europe. The butterfly has white wings with grey or yellow markings near the center or tip of the wing. It flies slowly and low over its shrubbery habitat. Males initiate courtship with females and can mate multiply, while females tend to only mate once in their lifetime.
The cabbage looper is a medium-sized moth in the family Noctuidae, a family commonly referred to as owlet moths. Its common name comes from its preferred host plants and distinctive crawling behavior. Cruciferous vegetables, such as cabbage, bok choy, and broccoli, are its main host plant; hence, the reference to cabbage in its common name. The larva is called a looper because it arches its back into a loop when it crawls.
Euchloe ausonides, the large marble or creamy marblewing, is a species of butterfly that occurs in western North America. It lays eggs on the terminal flower buds of a variety of plants in the mustard family, including introduced Eurasian species, and the larvae feed on the buds, flowers and fruit of these plants. In California, it has witnessed population declines since the 1980s, especially in the Central Valley and the Bay Area. In Washington, subspecies the island marble butterfly was listed as an endangered species under the Endangered Species Act in 2020.
The queen butterfly is a North and South American butterfly in the family Nymphalidae with a wingspan of 80–85 mm. It is orange or brown with black wing borders and small white forewing spots on its dorsal wing surface, and reddish ventral wing surface fairly similar to the dorsal surface. The ventral hindwings have black veins and small white spots in a black border. The male has a black androconial scent patch on its dorsal hindwings. It can be found in meadows, fields, marshes, deserts, and at the edges of forests.
Battus philenor, the pipevine swallowtail or blue swallowtail, is a swallowtail butterfly found in North America and Central America. This butterfly is black with iridescent-blue hindwings. They are found in many different habitats, but are most commonly found in forests. Caterpillars are often black or red, and feed on compatible plants of the genus Aristolochia. They are known for sequestering acids from the plants they feed on in order to defend themselves from predators by being poisonous when consumed. The adults feed on the nectar of a variety of flowers. Some species of Aristolochia are toxic to the larvae, typically tropical varieties. While enthusiasts have led citizen efforts to conserve pipevine swallowtails in their neighborhoods on the West coast, the butterfly has not been the subject of a formal program in conservation or protected in legislation. The butterfly is however of "Special Concern" in Michigan, which is on the Northern limit of its range.
The buck moth is a common insect found in oak forests, stretching in the United States from peninsular Florida to New England, and as far west as Texas and Kansas. It was first described by Dru Drury in 1773. The larvae typically emerge in a single generation in the spring. The larvae are covered in hollow spines that are attached to a poison sac. The poison can cause symptoms ranging from stinging, itching and burning sensations to nausea. Subspecies Hemileuca maia maia is listed as endangered in the US state of Connecticut. Subspecies Hemileuca maia menyanthevora, the bog buck moth, is federally endangered, and also protected by Canada and the state of New York. There were five populations known historically but only three still survive, one in the US and two in Canada.
Orgyia antiqua, the rusty tussock moth or vapourer, is a moth in the family Erebidae.
With over 850 species, the genus Nomada is one of the largest genera in the family Apidae, and the largest genus of cuckoo bees. Cuckoo bees are so named because they enter the nests of a host and lay eggs there, stealing resources that the host has already collected. The name "Nomada" is derived from the Greek word nomas, meaning "roaming" or "wandering."
The variable checkerspot or Chalcedon checkerspot is a butterfly in the family Nymphalidae. It is found in western North America, where its range stretches from Alaska in the north to Baja California in the south and extends east through the Rocky Mountains into Colorado, Montana, New Mexico and Wyoming. The butterfly is usually brown or black with extensive white and yellow checkering and some red coloration on the dorsal wing. Adult wingspan is 3.2–5.7 cm (1.3–2.2 in). Adult butterflies feed on nectar from flowers while larvae feed on a variety of plants including snowberry (Symphoricarpos), paintbrush (Castilleja), Buddleja, Diplacus aurantiacus and Scrophularia californica.
Papilio palamedes, the Palamedes swallowtail or laurel swallowtail, is a North American butterfly in the family Papilionidae.
The western tailed-blue is a Nearctic non-migratory butterfly that commonly takes flight during the spring and summer seasons of March–July. They can be best classified as having a presence of a tail on their hindwing, an upper surface that's bluish while the under surface is chalky-white with occasional black spots, and an orange spot toward the base of their tail. Their wingspan ranges from 0.875 to 1.125 inches. Larvae feed on various plant species including Astragalus, Lathyrus, Oxytropis, and Vicia. Adults feed on various things such as flower nectar, horse and coyote manure, urine, and mud.
Parnassius smintheus, the Rocky Mountain parnassian or Rocky Mountain apollo, is a high-altitude butterfly found in the Rocky Mountains throughout the United States and Canada. It is a member of the snow Apollo genus (Parnassius) of the swallowtail family (Papilionidae). The butterfly ranges in color from white to pale yellow-brown, with red and black markings that indicate to predators it is unpalatable.
Lycaena rubidus, the ruddy copper, is a butterfly of the family Lycaenidae. It is found in the western mountains of North America. Adults lay their eggs on plants of the genus Rumex, which later become the larval food plants. This butterfly gets its name from the brightly colored wings of the males, which are important in sexual selection. Its larvae exhibit mutualism with red ants, and are often raised in ant nests until they reach adulthood. Adults are on wing from mid-July to early August.
Climaciella brunnea, known sometimes by the common names wasp mantidfly, western mantidfly, and brown mantidfly, is a predatory neuropteran insect in the family Mantispidae.
