Thank you Gordon and Brian for your ID suggestions. I believe it's Efferia aestuans because the legs are black and not white and furry like Efferia albibarbis.
Maybe Efferia albibarbis? See http://bugguide.net/node/view/209956/bgp...
I agree with Gordon - Efferia aestuans - here is my post of one:

I'd agree with Dan that this is a robberfly. I'll guess that it is Efferia aestuans, but I'm not expert on robberflies. See http://bugguide.net/node/view/309001/bgp... for more information. What do you think? It looks good to me. You might simply want to call it Efferia sp. Landed on your leg, did it? These guys (and gals) are ferocious predators of other insects and often catch their prey in air. Apparently they can bite if provoked, but I've never been bitten by one and I've photographed many of them. Cool photos!
Thanks Dan :)
It's a robber fly of some kind. Maybe someone else can be more specific.

Can anyone help with an ID?
