Blue dasher (Pachydiplax longipennis)
For reference, the shadow darner is larger, has a more slender abdomen, and the abdomen has complex mosaic markings. I suspect that they don't spend a lot of time perching, either--I'm not familiar with the species, but most darners are very active during the day.

Blue dashers are a little more than half the size of a shadow darner, have blue abdomens (on the males) or brown and yellow markings, as well as that striped thorax and white face. They spend a lot of time perching and are one of the more approachable species of dragonflies. This is definitely a blue dasher.

(I'm not going to guess on the sex here, since I still have trouble with it sometimes.)

Looks rather to be Pachydiplax longipennis
but can't be certain of gender from this angle. Looks like it might be female.
