Glasswing – Greta Oto
The Glasswing (Greta oto) is a brush-footed butterfly, and is a member of the subfamily Danainae, tribe Ithomiini, subtribe Godyridina. Its wings are translucent, with a wingspan of 2.2 to 2.4 in (5.6 to 6.1 cm). Its most common English name is glasswing, and its Spanish name is “espejitos”, which means “little mirrors.” Indeed, the tissue between the veins of its wings looks like glass, as it lacks the coloured scales found in other butterflies. The opaque borders of its wings are dark brown sometimes tinted with red or orange, and its body is dark in color.
