I.D. verified by Dennis Paulsen  "
That indeed is a young female Dot-tailed Whiteface, from its color pattern and subgenital plate (pair of peglike protuberances). I guess the "chin" in DTB is the labium, the jointed structure under the mandibles. That is fairly variable in color." Dennis

I.D. verified by Alan Myrup
"Yes, your label, Leucorrhinia intacta, (Dot-tailed Whiteface) is correct. The ventral view of the subgenital plates is the key." Alan
