Butterflies from Chiapas and Oaxaca, Mexico
From July 11-23, 2015, Sheridan and I spent four days in the central Chiapas area as part of the GBNA biennial meeting, and then a week in south/central Oaxaca as part of a private group, ably organized and lead by Michael Retter. This was a birding trip, and butterflying opportunities were moderate, yet the butterfly numbers were outstanding! I've probably made errors with some of my IDs - any help in sorting them out would be greatly appreciated!:
Sierra Madre del Sur, Oaxaca. Genus Citheronia - it looks most like regalis, which does not occur in Mexico; azteca is close, but are there any other possibilities?
La Cumbre, Oaxaca.
Sumidero Canyon, Chiapas.
Sumidero Canyon, Chiapas. I believe that this is the same specis that occurs rarely in the LRGV of southern Texas.
