I visited the Gorgas Science Foundation's research facility at Rancho del Cielo (c. 3,800 feet/1,160 meters; lat/long 23.10026,-99.193411), c. 4 miles NNW of Gomez Farias, Tamaulipas, during March 10 - 13, 2006. Conditions were not typical, as the experienced visitors said that it was the driest that they'd ever seen it. Nonetheless, there were quite a few flowering plants in the clearings, and the butterfly diversity was very good for such a small area.
Many of the hairstreaks shown here are not identified, and I've probably made errors with some of my other IDs - any help in sorting them out would be greatly appreciated!:
