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!:
