Description: 16-19 mm. Fresh adults are bright orange on the ventral side. the identifying factor for this species are the yellow viens on the ventral hindwing. Females are slightly larger and more elongate. Above, male E. berryi looks much like E. pilatka. They are golden yellow above with a black stigma. The dark brown margins are thicker than that of E. pilatka.

 

Habitat and Distribution: Marshes and swamps. This butterfly is fairly difficult to find but at times can be locally common. We have found them common in February and March in Big Cypress National Preserve in SW Florida when the thistles are in bloom. It has been rported from Key Largo however I am unaware of any confirmed sightings. 

 

Host Plant: sedges
