2- Eunica monima(dingy purplewing)
- Eunica tatila(Florida Purplewing)
Eunica is a of nymphalid butterflies in the Biblidinae, commonly known as purplewings. The genus contains approximately 40 distributed throughout the . Species exhibit notable variation in eyespot patterns on the hindwing surface, with phylogenetic studies indicating an evolutionary trend toward reduction in eyespot number coupled with increase in size of retained spots. Several species serve as bio-indicators of undisturbed tropical forest.

Identification
Distinguished from other nymphalid by combination of: (1) eyespot patterns on hindwing (variable among ), (2) purple to brown wing coloration, and (3) Biblidinae characteristics including reduced forelegs. Species-level identification requires examination of eyespot number, size, and arrangement on ventral hindwing, as well as dorsal color pattern and presence of .
