We have a new contributor - Nancy Collins, who is particularly interested in Tree Crickets (Oecanthinae).  She contributed several great links - all on BugGuide:

Milbert’s Tortoiseshell – Aglais milberti

Friday, February 27th, 2009

In most years this butterfly is fairly common in our part of Wisconsin, but in some years we see hundreds of caterpillars and butterflies.  The caterpillars eat stinging nettle (Urtica dioica), and in peak years the caterpillars can completely decimate the leaves on our nettle plants.

2005 was one of those peak years.  In our July 21 butterfly count, we saw 134.  We would have counted even more if we had walked the driveway earlier in the day, before the sun got too hot.

Caterpillars feed in groups, on top of nettle leaves.

The chrysalis has a beautiful gold sheen.

And basking on the driveway - where I most often see them.
