Spotting

The markings on the abdomen look like that of a Pennant of some kind...they usually have wing patterns. The thing about pennants though, they aren't exactly huge as far as dragonflies go. Check out www.odonatacentral.org

I find this link a great intro to dragonflies.

It's in the family Libellulidae (Skimmers).Was there a wing pattern or do you have more pics? I may be able to get this down to species.

Clearly, but it was huge! It's wings were so cool, though.

clearly a dragonfly!
