Silkmoth of the week: Caio cf chiapasiana

After a pupal stage of almost three months, the first moths finally emerged this week. Caio chiapasiana was only recently described  by Brechlin & Meister (in 2010). I don't have that original description of the species, but I believe the inward line under the forewing 'eyespot' is one of the determining characteristics. That together with the size, the pure white eggs and the location where the female parent was caught (Chiapas/Mexico) is enough for a fairly accurate identification. So, I'm 99% sure that this is indeed Caio chiapasiana. The exact distribution of this species is still somewhat unclear. So far they are only confirmed for Chiapas (Mexico), but it could be possible that they also occur further south.
