Ducal Arcas

Description:

Unique identifying traits for Arcas include a hindwing anal lobe cleft approximately 4 mm long and trail up to 15 mm in length coupled with rows of emerald colored scales on the ventral wing surfaces.
Arcas ducalis can be distinguished by the well-defined carmine disc and metallic yellow margin on the ventral hindwing (Bálint 2002, 2006).
Considered rare or vulnerable, these species are the most exquisite of all Neotropical Theclinae, typical of large areas of natural wet forest and usually disappearing in disturbed areas.
They are easy to find where present and are thus good indicators of undisturbed forest systems.

The town of the coordinates (lat: -22.538579, long: -43.228141) that I used for search, is not DUQUE DE CAXIAS, as reports the search map tool of this page, but PETRÓPOLIS, as shown here:
