Crex Meadows (and surrounding areas)For Crex Meadows, I began to document the butterflies slowly in the summer of 2007. By 2009, I set a goal of visiting Crex Meadows once a week with the intent to photograph as many of the individual species as possible. As of October 2012, I have documented 90 species of butterfly with clear photographs. There are 3 additional species that are controversial in Burnett county including Spring Azure, Pearl Crescent and Atlantis Fritillary. There are also a few species, including the Hackberry emporer and Pepper and Salt Skipper, which I have seen but not been able to photograph at this time.
There are also a number of moths which have been documented, including all three Clearwings found in wisconsin, a buckmoth that may be the new specie, Midwestern Fen Buckmoth and several tiger, and silk moths.
