Virginian Tiger Moth
Spilosoma virginica
August 26, 2002

These snowy arctiids are common throughout the summer.  They are very docile in the morning - slow to take flight when disturbed.
My wife Betsy is lifting the wings with a 
twig to show the interesting pattern on 
the abdomen.  This is present in a variety of colors and shapes in many of the Tiger Moths.  For a comparison of the similar-looking Agreeable Tiger Moth, go here, and for the Fall Webworm - here.
