this is about the size of the whole palm of my hand. We are located in mid Texas and it’s the beginning of June! It’s been sitting in a pot for about 5 hours and hasn’t moved.

Dear Ashley,
This Robber Fly in the family Asilidae is an accomplished predator.  Based on images posted to the Plants and Insects of Goodwell and Texhoma site, this is a male
Efferia aestuans, a species with no common name.

Dear Hannah,
This is one of the largest and most impressive of the North American Robber Flies in the family Asilidae.  This is a Belzebul Bee-Eater,
Mallophora leschenaulti, which you can verify by comparing your image to this image on BugGuide.

Robber Fly, we presume

Robber Fly, we presume

Dear Beck Shawn and the 3 kids,
We cannot imagine that this is anything other than a Robber Fly in the family Asilidae.  This individual looks like the same species as this previous posting of a Robber Fly from Melbourne submitted in December 2012.  It is not uncommon to have seasonal sightings of species of insects as most live no more than a few weeks as adults.  Robber Flies are top of the insect food chain predators that can take other predators, including Yellowjackets and other Wasps, on the wing.  Like other flies, Robber Flies have a single pair of wings, yet having one pair less than most insects seems to have improved rather than to have inhibited their ability to fly.
  Perhaps one of our readers will be able to assist in this identification.

Update:  December 20, 2014
We just received a comment that this is Neoaratus hercules, a large Robber Fly
It is pictured on the Atlas of Living Australia and on Insect Net it is called a Hercules Robber Fly.
