Strymon yojoa
Yojoa Scrub-Hairstreak
Strymon yojoa is a small hairstreak butterfly in the family Lycaenidae, commonly known as the Yojoa Scrub-Hairstreak. It is native to North America and belongs to a genus of butterflies often associated with scrubland and open habitats. The species was originally described as Thecla yojoa by Reakirt in 1867 and later transferred to the genus Strymon.

Theclinae
hairstreaks, elfins
Theclinae is a subfamily of Lycaenidae butterflies comprising hairstreaks, elfins, and related groups. Members are characterized by small to medium size, often with tail-like projections on the hindwings and intricate underside patterns. Many species exhibit myrmecophilous relationships with ants, and larvae possess a specialized dorsal gland (Newcomer's gland) that secretes sugary fluids to attract ant protectors. The group shows high diversity in tropical regions, particularly the Neotropics and Southeast Asia, with fewer migratory species compared to other butterfly groups.
Zizula cyna
cyna blue

The species is active from March to November in most of its range, with adults feeding on flower nectar and larvae developing on flower buds of Acanthaceae species.
