Perisomena caecigena

Perisomena caecigena, the autumn emperor moth, is a moth of the family Saturniidae. The species was first described by Franz Josef Kupido in 1825. It is found in Italy (east of Venice near the Croatian border) and then from south-eastern Austria through Hungary, Slovenia, Croatia, Serbia, Albania, the western Ukraine, Romania, Bulgaria and Greece to most of Turkey and the Caucasus Mountains of the Republic of Georgia, Armenia and Azerbaijan. There is also an isolated population in the mountains of Lebanon and Israel. Subspecies stroehlei is endemic to the Troodos Mountains of Cyprus.

The wingspan is 62–88 mm for subspecies caecigena and 40–65 mm for males and 48–90 mm for females of subspecies stroehlei. Adults are on wing from late September to early November.

The larvae feed on Quercus species, including Quercus robur, Quercus petrea, Quercus pubescens, Quercus cerris and Quercus ilex, but also Populus alba, Populus nigra, Fraxinus, Pyrus and Prunus. Salix might also be a host plant, since larvae have been reared on Salix caprea in captivity.

gollark: Instead of asking people to write a complex project for you, learn with simpler projects.
gollark: Yes, but you appear to not know how to write this, so learn.
gollark: The docs are really quite good.
gollark: Some project ideas:- thing to connect to a simpler HTTP-based API- in-game file transfer
gollark: Look, either you have the skill to write this - in which case read the docs and write it - or you don't, in which case do other projects to learn.
