Variable Cracker

Variable Cracker, originally uploaded by andiwolfe.

The Florida Natural History Museum has a butterfly exhibit, which is amongst the best I have ever seen. The 'aviary' is not in an enclosed conservatory, but is open to the air. There are mesh screens to keep the butterflies in, but allow the air to circulate. I only had my walkabout lens (Canon 24-105 mm f/4.0 L). I really needed the 70-200 mm zoom for this excursion. This Variable Cracker butterfly was one of the most interesting to see. The docent on duty told me that it is the only butterfly that makes a sound audible to humans, and that it sounds like a taser. I'm not quite sure what a taser sounds like, and I hope I never have the opportunity to learn that sound :-)
