Common Whitetail -Dragonfly

Ahh. . that solved a question I had while looking at my reference. Someone falsely listed a Libellula Julia as a Lybellula Lydia because of a similar (partially) blue abdomen, which made me question a spotting I listed right before this. lol. But on the same page was a properly labled Libellula Lydia male, with the banded wings and blue abdomen. Thanx! : ))

Didn't realize my reference stated that it was also a common whitetail, aside from libellula lydia..lol. If you don't mind me asking, if you ever check back to this, how did you know it was female? : )
