4cm long moth
Tropical forest -altitude 1800mts-
Definitely Halysidota sp. and impossible to get closer without the native specimen. There are too many around and the variability within the genus/species is also to be considered.
I believe Fyn was referring to Halysidota as the genus, not Lophocampa. Looks a lot like this one, though I am not sure if you have other similar species in Mexico. Halysidota is notorious for being unidentifiable by photos. http://bugguide.net/node/view/217944/bgp...
Tussock Moth species, Looks a lot like the North American Banded Tussock Moth - Lophocampa caryae.
