Red Admiral Butterfly
April, 2012 - The red admirals have migrated north this year in record numbers, due to the warmest March on record here in the American Midwest. At Castle Rock State Park near the Rock River, I would kick up hundreds of them in just a few dozen yards of walking. It reminds me of the painted lady population explosion we had a few years ago, but they weren't nearly as numerous.

April 2013 - This spring has been one of the coldest on record, and there are no butterflies at all as of April 23rd.
