Galveston Island

Fly vs. Fly

When the sun is high in the sky and the light isn’t conducive for bird photography, I like to bust out the macro lens and look for smaller wonders. I found this robber fly taking a break among the scrubby beach vegetation while its neurotoxic, proteolytic saliva paralyzes and chemically digests the insides of its current victim. Charming. It’s a good thing (for us) that these flying assassins exclusively prey upon arthropods – mostly other insects at that.
