Variegated Meadowhawk, Sympetrum corruptum

Do dragonflies eat spiders? Yes, and here's proof. (Count the legs.)

I wish I knew where he got the victim, but I don't. I was watching from the bank
of McCreery Lake; this male left for a few seconds and came back with an arachnid.

I have only seen them take flying prey, and spiders don't fly, so... go figure.
