Field notes from Isla Colon:

 

The genus Therinia contains some unusual-looking Saturniid moths, and in general they all resemble one another. My determination for this specimen was made with its range in mind -- other very similar species are limited to South America. T. transversaria, on the other hand, is widespread in Central and South America.

 

I have seen this insect twice on Isla Colon, both times at mercury vapor lights set up in jungle/secondary growth sites near the seashore.
