A species of Green hairstreaks

Callophrys spinetorum, the thicket hairstreak, is a butterfly of the family Lycaenidae. It was described by William Chapman Hewitson in 1867. It is found in North America from British Columbia through the Rocky Mountains to New Mexico and Mexico and through California to Baja California. The habitat consists of pinyon-juniper forests, mixed woodlands, and coniferous forests. The wingspan is 25–32 mm. The upperside is steel blue and the underside reddish brown. The hindwings with a white postmedian band which forms a W shape near the tail. Adults are on wing from May to August in one generation per year. They feed on flower nectar. The larvae feed on Arceuthobium species.

Life Cycle of Thicket Hairstreak
Egg The egg stage marks the beginning of thicket Hairstreak's life cycle. The eggs are usually laid on plants and are small, oval or round, and often blend with the host plant in color.
Larva The larva, or caterpillar, stage is where thicket Hairstreak experiences significant growth. The caterpillar has a tubular body, chewing mouthparts, and undergoes several molts as it grows larger.
Pupal During the pupa stage, thicket Hairstreak is encapsulated within a chrysalis. It's a transitional stage where the body is reorganized from a caterpillar to an adult. The pupa is generally immobile and defenseless.
Adult Emerging from the pupa, the adult thicket Hairstreak’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

How Can You Attract Thicket Hairstreak
Adult thicket Hairstreak may be attracted using bait that includes overripe fruits or sweet substances like honey as they feed on nectar from flowers. The bait should be placed in areas where the adult thicket Hairstreak is known to frequent. It's vital to avoid using harmful substances that can affect the health of thicket Hairstreak or other wildlife.
Rectangle
Habitat Preferences of Thicket Hairstreak Through Different Life Stages
The eggs of thicket Hairstreak are usually laid on the flowers or buds of the host plant, and after hatching, the larvae tend to remain on the host plant, feeding on leaves or flowers. Pupae of thicket Hairstreak are typically found camouflaged on the stem or underside of leaves of the host plant. Adults can commonly be found in fields, meadows, or woodland edges with abundant flowering plants, as they rely on nectar. To locate the different growth stages, searching in and around host plants in suitable habitats is essential. For larvae, examine leaf surfaces and buds; for pupae, inspect stems and leaf undersides; for adults, observe for their activity near nectar sources during sunny days.
Rectangle
When is the Best Time to Observe Thicket Hairstreak
Searching for thicket Hairstreak should be done during the daytime as most species within the order Lepidoptera are diurnal, although there can be exceptions. Early morning or late afternoon can be opportune times when thicket Hairstreak is most active or resting, respectively.
Rectangle
What is the Best Weather to Observe Thicket Hairstreak
Warm and sunny weather typically enhances the activity of thicket Hairstreak as it creates ideal conditions for flying or basking. Avoid searching during rainy or cold days which cause thicket Hairstreaks to be less active and more challenging to locate.

Hurt Plant

When the larva of thicket Hairstreak feeds, it chews on the leaves of plants indiscriminately, which can lead to defoliation. Depending on their numbers, the damage can range from mild to severe, potentially leading to reduced photosynthesis and weakened plant vitality.

Pollination Behavior Reason
Eat Pollen Or Nectar
Thicket Hairstreak, with its eye-catching wing patterns, flutters from flower to flower. While primarily searching for nectar, it unintentionally collects and transfers pollen, aiding in the fertility of numerous flowering plants. This incidental interaction exemplifies nature's complex web of mutual benefits.

Boisduval's blue
Boisduval's blue

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'.

Lupine Blue

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 icarioides missionensis
Icaricia icarioides missionensis

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.

Eumedonia eumedon
Eumedonia eumedon

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.

Southern Brown Argus

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.
