Sloe hairstreak

Larvae of boisduval's blue are extremely small and rarely seen. The males' top wing grades from ice blue in the center to deep sky blue, exhibiting a dazzling iridescent fluctuation in range under direct, full sunlight. Black margins on the upper wing sport long, white, hair-like scales. A constellation of jet-black dots frames the extremities of the ventral surface, its pattern adroitly complementing the wing shape and throwing it into spectacular relief against the shimmering silvery pearlescent background. A fascinatingly muted hint of dark ice blue bleeds faintly up from the body, permeating the veins throughout for the palest, most delicate emphasis. The body shape, eyes, antennae, and appendages give it a uniquely exquisite poise. The males' bodies are dark-blue or brown. The females' upper wings are dark brown but otherwise mirror the males'.

Icaricia lupini, the lupine blue, is a butterfly of the family Lycaenidae. It is found from south-western Canada, south through much of mountainous and intermountain western United States and high plains to northern Mexico. The wingspan is 22–29 mm. Adults are on wing from June to August in one generation in the Sierra Nevada of eastern California. Elsewhere, there are several generations from March to July. The larvae feed on Eriogonum umbellatum and Eriogonum fasciculatum. Adults feed on flower nectar. The hairs of the caterpillars can cause skin irritation (urticaria).

Icaricia shasta, the Shasta blue, is a butterfly of the family Lycaenidae. It is found from the northwestern United States to southern Saskatchewan and Alberta. The wingspan is 20–22 mm. Adults are on wing from June to August. The larvae feed on Lupinus lyalli, Astragalus spatulatus, Astragalus calycosus, and Trifolium dasphyllum.

Icaricia saepiolus, the greenish blue, is a butterfly of the family Lycaenidae. It is found from the northwestern United States to southern Saskatchewan and Alberta. The wingspan is 21–28 mm. Adults are on wing from June to August. The larvae feed on Trifolium monathum, Trifolium longipes, and Trifolium wormskioldii.

The endangered Mission blue has a wingspan around 21–33 millimetres (0.83–1.3 in). Larvae are extremely small and rarely seen. The males' top wing grades from ice blue in the center to deep sky blue (misregistered as turquoise/cyan to violet by most photographic equipment, the wing color carries no hint of green or purple, strictly capturing an enthralling spectrum of purest, clearest, richest, brightest blue) exhibiting a dazzling iridescent fluctuation in range under direct, full sunlight. Black margins on the upper wing sport "long, white, hair-like scales". A constellation of jet-black dots (misregistered as dull gray by most photographic equipment) frames the extremities of the ventral surface, its pattern adroitly complimenting the wing shape thrown into spectacular relief against the shimmering silvery pearlescent background, with a fascinatingly muted hint of dark ice blue bleeding faintly up from the body and permeating the veins throughout for the palest, most delicate of emphases. Body shape, eyes, antennae, and appendages possess it of a uniquely exquisite poise. The males' bodies are dark-blue/brown. Females' upper wings are dark brown, but otherwise mirror males'. The larvae only feed on the leaves of the three host lupine plants (Lupinus albifrons, Lupinus formosus, and Lupinus variicolor) native to their habitat. The plants are necessary for survival for the Mission blue. Thus, the butterfly's fate is closely tied to that of the three species of lupines as the plants provide food and shelter for the butterfly in its larval stage. The adult Mission blue drinks the nectar of a variety of flowers, many in the sunflower family, using its long proboscis which extends from the underside of its head.

The Little Sunflower Bläuling (Aricia agestis) is a butterfly (butterfly) from the family Bläulinge (Lycaenidae).

Endemic to specific ecosystems, eumedonia eumedon exhibits a remarkable adaptation in its larvae, which engage in a mutualistic association with ant species. These larvae secret a sweet substance that attracts ants, which in return provide protection against predators. The adult form is known for its striking wing patterns that serve as a visual deterrent to potential threats and plays a role in intraspecific communication during the breeding season.

In specimens [ of astrarche ] from the Canaries the red macular band of the upperside is occasionally quite uncommonly broad and of even width, so that it forms a regular band, only transected by the black veins; this is ab. cramera Eschsch. (= canariensis Black.) (80 a). I also caught very extreme specimens of this form on the slopes of the Aures Mts. in Algeria, although only singly; on the other hand I met on the Canaries with specimens of astrarche which certainly did not belong to cramera, but rather to calida.

Western honey bee（Apis mellifera） is the most common species of honeybee in the world. Among the first domesticated insects, its cultural and economic impact on humanity has been vast and far-reaching, providing honey, wax and its services as a pollinator. Western honey bee faces challenges worldwide, such as colony collapse disorder, and populations are thought to be decreasing.

The monarch butterfly (Danaus plexippus) is the most recognizable butterfly in North America. It is best known for its appearance, but should be better known for the fact that it has a 3000-mile migration that takes the butterfly 4 generations to complete. Their diet is also a natural deterrent for predators, as they eat milkweed, a poison that induces vomiting.

The japanese rhinoceros beetle (Trypoxylus dichotomus) is a massive beetle about the size of the palm of a hand. It's distinguished by its long Y-shaped horn, which it uses to fight other males with. It's a nocturnal bug that feeds on sap and sweet fruits. This species is sometimes kept as a pet due to its unique appearance and simple care requirements.

The silken threads produced by silkworm during its larval stage have been highly coveted for millennia, manifesting as a luxurious fabric in human society. Remarkably, this creature has a singular diet, feeding exclusively on the leaves of its primary host plant from which it extracts the necessary nutrients to facilitate its transition into a non-feeding, winged adult.

Menelaus blue morpho (Morpho menelaus) is a gorgeous butterfly with large, royal blue wings. Linnaeus named the genus Morpho the Aphrodite-Ancient Greek goddess of love and beauty for its extreme beauty. It is native to tropical rainforests. Though many butterfly gardens now cultivate them in captivity, there are still many people who never get a chance to see them.

While the atlas moth (Attacus atlas) can't tell you where to find your country on the map, it does earn its name through other means. It is one of the largest moths in the world, with a wingspan that is far larger than its body, creating an abnormal comparison. In India, their silk is gathered in a non-commercial capacity and is considered to be more durable than the domestic silkworm.

Both sexes reach about 5 mm in body length. Females and immatures of both sexes are brown but have color patterns by which they can be distinguished from related species. Also, the males dance to attract females.

Often confused for the ladybug, multicolored asian ladybeetle (Harmonia axyridis) is a separate species that, unlike the ladybug, is a household pest. It is considered particularly annoying for its habit of returning to places from which it is removed. One of the most variable species in the world, there are many different colors and patterns multicolored asian ladybeetle may display, making identification potentially difficult.
