Spending alot of time in Crex Meadows taking pictures this last few months, I have come across a few sites that might be of interest:
Bug guide is probably the all around coolest:
www.bugguide.net
In their forums sections, I picked up some good tips on close up photography. There are some amazing pics of caterpillers developing in their eggs and Teeny little parasitic bugs crawling around on the caterpillers.
Another specific to butterflies and moths is this one:
Butterflies and Moths of North America | Occurrence maps, species accounts, checklists, and photographs
From the above site, I have the Minnesota contact person and am waiting for a response on how to submit some of the local butterflies I have snapped pics on, that do not show records in my county.
As Crex Meadows is in Wisconsin, I came to this site in attempts to ID various butterflies and found it very helpful:
wisconsinbutterflies.org | The Butterflies
The above site is very helpful, listing similar species and details on how to tell them apart.
Browsing his site, I found several of the photos I had taken at the meadows were not confirmed via photo submission. So far, I have submitted 7 different types of butterflys that have allowed this site to update their map indicating a photo has been submitted (and confirmed) for a particular county in Wisconsin. 2 of these seven were butterflies that had only a historic reference black dot, and now they have a photo confirmation.
