The large blue is a species of butterfly in the family Lycaenidae. The species was first defined in 1758 and first recorded in Britain in 1795. In 1979 the species became mostly extinct in Britain but has been successfully reintroduced with new conservation methods. The species is classified as "near threatened" on the IUCN Red List of Threatened Species. Today P. arion can be found in Europe, the Caucasus, Armenia, western Siberia, Altai, north-western Kazakhstan and Sichuan.
The common blue butterfly or European common blue is a butterfly in the family Lycaenidae and subfamily Polyommatinae. The butterfly is found throughout the Palearctic and has been introduced to North America. Butterflies in the Polyommatinae are collectively called blues, from the coloring of the wings. Common blue males usually have wings that are blue above with a black-brown border and a white fringe. The females are usually brown above with a blue dusting and orange spots.
Lycaenidae is the second-largest family of butterflies, with over 6,000 species worldwide, whose members are also called gossamer-winged butterflies. They constitute about 30% of the known butterfly species.
The chalkhill blue is a butterfly in the family Lycaenidae. It is a small butterfly that can be found throughout the Palearctic realm, where it occurs primarily in grasslands rich in chalk. Males have a pale blue colour, while females are brown. Both have chequered fringes around their wings.
The holly blue is a butterfly that belongs to the lycaenids or blues family and is native to the Palearctic.
Phengaris alcon, the Alcon blue or Alcon large blue, is a butterfly of the family Lycaenidae and is found in Europe and across the Palearctic to Siberia and Mongolia.
Orachrysops niobe, the Brenton blue, is a species of butterfly in the family Lycaenidae and is endemic to South Africa.
Celastrina is a genus of butterflies in the family Lycaenidae found in the Palearctic, Nearctic, Indomalayan and Australasian realms.
The Appalachian azure is a butterfly in the gossamer wings family Lycaenidae. The male is light blue on the upperwing with a narrow, dark line running along the edge of the forewing. The underwing is chalky white and is dotted with small, pale dark spots. The very back of the hindwing has a row of dark spots running along the edge and contained by a faint zigzagging band. Females are similar to the males but have broad dark wing borders instead of the male's narrow ones. The adult butterfly has a 1.1–1.4-inch (2.8–3.6 cm) wingspan. It is the largest azure in the area.
Celastrina ladon, the spring azure or echo blue, is a butterfly of the family Lycaenidae. It is found in North America from Alaska and Canada south of the tundra, through most of the United States except the Texas coast, southern plain and peninsula Florida; south in the mountains to Colombia, also on Molokai island, Hawaii.
Celastrina neglecta, the summer azure, is a butterfly of the family Lycaenidae. It is found in North America. Layberry, Hall, and Lafontaine, in The Butterflies of Canada, describe the species:
The upper surface is pale blue with an extensive dusting of white scales, especially on the hindwing. In some females the blue is almost entirely replaced by white with a small amount of blue near the wing bases. Females have a broad blackish-grey band on the outer third and costa of the forewing. The underside is chalky white to pale grey with tiny dark grey spots and a zigzagged submarginal line on the hindwing.
Celastrina serotina, the cherry gall azure, is a butterfly of the family Lycaenidae. It is found across North America as far north as the treeline. Its flight time is between mid-May and mid-June in eastern Ontario after the spring azure and before the summer azure. The larva has been reported to feed on galls of eriophyid mites and apparently also on the mites themselves, making them one of the rare species of carnivorous Lepidoptera. It is commonly found around woodland roads of upland mixed deciduous hardwood forests which are surrounded by wetlands.
Celastrina lucia, the lucia azure, northern azure, eastern spring azure or northern spring azure, is a species of butterfly of the family Lycaenidae. It is found eastern North America, ranging from the Maritimes south through the Appalachian Mountains to West Virginia.
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.
Allium geyeri or Geyer's onion is a North American species of onion widespread in the western United States and in western Canada. It is found in the Rocky Mountain States from New Mexico to Idaho, Great Basin, the Pacific Northwest, Texas, South Dakota, Arizona, Manitoba, British Columbia, Alberta and Saskatchewan.
Celastrina idella, the American holly azure, is a species of butterfly of the family Lycaenidae. It is found on the east coast of the United States.
Celastrina humulus, the hops azure, is a species of blue in the family Lycaenidae. It is found in North America. The main host plant is wild hops. They can change their body temperature by behaviors like basking or sitting in shade.
Celastrina nigra, the dusky azure, is a butterfly in the family Lycaenidae. The species was first described by William Trowbridge Merrifield Forbes in 1960. It resides in the extreme northeast corner of the U.S. state of Georgia. The larval host plant is Aruncus dioicus.
Lappula occidentalis, also known as flatspine stickseed, flatspine sheepburr, western stickseed, Lappula redowskii, or Redowski's stickseed, is a biennial forb native to North America and parts of Europe and Asia. It belongs to the family Boraginaceae. Variants include L. redowskii var. cupulata and L. redowskii var. redowskii, which differ in fruit morphology from the type specimen.
