Diet

• Adults feed on nectar from a variety of small flowers, including asters, legumes, and other low-growing plants.

• The caterpillars feed primarily on legumes (Fabaceae).

• The caterpillars are sometimes tended by ants, which may collect the sugary secretions produced by the larvae and in return provide some protection.

Range

• The Eastern Tailed-Blue is widely distributed across North America, Mexico, and parts of Central America.

• In the Zihua area, it would be considered uncommon and localized, occurring mainly in open habitats where suitable leguminous plants grow.

Habitat

• It favors open, sunny habitats, including meadows, grasslands, fields, roadsides, pastures, gardens, and disturbed areas.

• It is rarely associated with dense tropical forest and is more likely to occur where grasses and low herbaceous vegetation are abundant.

• Adults usually fly close to the ground and frequently settle with their wings closed, making the small tails and orange hindwing spots important identification features.

Description

• A small butterfly with a wingspan of approximately 22–32 mm.

• The male is generally pale blue above, while the female is darker, with more extensive gray or brown scaling and reduced blue.

• Both sexes have a distinctive small tail on each hindwing, accompanied by an orange spot near the tail and a pair of black spots.

• The underside is gray or pale brown with numerous black spots, giving the butterfly a delicately speckled appearance.

• The hindwing underside usually has a narrow orange band near the tail, making the species recognizable even when the wings are closed.
