From a peppermint Pericopinae. I recorded this video on-site in northern Costa Rica a few years ago. When I reached down to pick up this moth, it was hard to avoid noticing the behavior. The moth, Chetone angulosa (Erebidae: Pericopina) ((used to be Arctiidae)), has a common defensive mechanism for this group – they . . . → Llegir més: Perfum d'arna

If you scroll down a bit you can see the english translation. At first glance this looks like a standard taxonomy paper with bare-bones species descriptions. You might even think to yourself, “huh, wonder why they are describing species from only one specimen”.

Who can tell me anything about this butterfly? The most you’re getting is that it is from the Western half of the US.

Know this butterfly? It’s OK, no one really does. It is in the genus Apodemia (Riodinidae), but the taxonomy of this group is a disaster… and don’t even get me started on the subspecies. This specimen was photographed in September, meaning it is most likely to be Apodemia mormo (mormo) based . . . → Llegir més: Stupid buttefly of the week Comparteix aquest!
