I had posted versions of these photos some time ago, but felt they deserved a re-post with more careful processing. I scared this dragonfly up from the grass while birding on a cool spring morning, and it landed on some dock (Rumex) with pretty pink seed pods. The sky had a nice light overcast for soft lighting. I have never seen this species again--it is said to be active mostly at dawn and dusk.
Dead fly stuck on a mentzelia leaf by its wings.
Big, like a pinacate.
On a cholla bud.
The Pterygota are a subclass of insects that includes the winged insects. It also includes insect orders that are secondarily wingless (that is, insect groups whose ancestors once had wings but that have lost them as a result of subsequent evolution).
