Cyanophrys herodotus
(Fabricius, 1793)
Tropical Greenstreak, Tropical Green Hairstreak
Cyanophrys herodotus is a small Neotropical () described by Fabricius in 1793. It ranges from Mexico through Central America to Argentina, with rare strays reaching southern Texas. The inhabits open disturbed areas in tropical and subtropical forests at 600–2,000 m elevation, where feed on flower nectar and feed on leaves and flowers of various shrubs and trees.

Identification
Distinguished from other green by combination of Neotropical distribution, small size (22–29 mm wingspan), and presence in open disturbed forest at mid-elevations. The green upper surface and tailed separate it from non-hairstreak lycaenids. In southern Texas, rare strays may be confused with resident green hairstreaks but occur later in season (May–October) and are less frequently encountered.

Taxonomic History
Originally described as Hesperia herodotus by Fabricius in 1793. Later transferred to Thecla, and currently placed in Cyanophrys. The specific epithet references the Greek historian Herodotus, though the reason for this naming choice is not documented in available sources.
Elevation Range
The documented elevation range of 600–2,000 meters suggests the is primarily mid-elevation, avoiding both lowland tropical forests and high montane regions. This may reflect thermal preferences or distribution patterns.
