Hi bugman, As a avid daily visitor to your site, I have searched many pages and answered many questions. Thanks for the hard work! This past summer ( 2007) I participated in the New York State Dragonfly and Damselfly Survey (NYDDS). While I am certainly no expert (not even close) I hope that you can use these two photos of a male (top)[actually left] and female (bottom) [right] Widow Skimmer Libellula luctuosa. These animals were photographed in upstate NY, Madison County in the month of July.
Thank you ever so much for sending us your wonderful images of a pair of Widow Skimmers.
