Diet

• Caterpillars: The larvae are associated with woody plants.

• Adults: Feed on flower nectar and may also obtain nutrients from other plant-derived sources.

Range

• The Thoria Hairstreak occurs from Mexico through Central America and southward into northern South America, reaching Venezuela and extending eastward through parts of the Guianas and Brazil.

• Guerrero is within its Mexican range, and the species occurs in the warm tropical regions of western Mexico.

• It can occur in the Zihua area, particularly where suitable tropical woodland and forest-edge habitat remain.

Habitat

• Associated with tropical and subtropical forest, woodland edges, clearings, and secondary vegetation.

• It is generally encountered in warm, relatively sheltered environments where flowering plants provide nectar and suitable larval host plants occur.

• Like many small hairstreaks, it can be difficult to notice because adults often remain among foliage rather than making conspicuous flights.

Description

• A small hairstreak, with a wingspan of approximately 25–32 mm.

• The upper surface is predominantly brown to dark brown, with subtle coloration that can make the butterfly appear rather plain when viewed from above.

• The underside is more distinctive, with a grayish to brown ground color crossed by fine darker lines and contrasting markings toward the hindwing.

• The hindwing bears small tails, accompanied by the typical hairstreak pattern of contrasting markings near the anal angle.

• A subtle orange or reddish spot near the hindwing anal area, together with pale and dark markings around the tail, can help separate it from other small brown hairstreaks.

• Males and females are similar in general appearance, although differences in the extent of dark scaling and wing markings can occur.

• Its restrained coloration and small size make it much easier to overlook than the brilliantly colored hairstreaks found in the same forests.
