Eccritosia zamon
Near the Jung Rd. low-water crossing of the Pedernales River between Fredericksburg and Stonewall, TX., Gillespie County, Texas, USA
July 26, 2008
Size: Very large
This huge Robber Fly slow-buzzed by my ear carrying a freshly caught Apis mellifera (visible and dwarfed in the image between the fly's legs) and landed on a nearby dead plant stem. Its orange tail glowing in the sunlight was nearly as impressive as its size. This is one creature that cannot be ignored! I'm guessing it's a male but would appreciate it if someone could definitively sex the fly for me. Thank you!

Pointed abdomen tip = ♀

I think this is a male. Though I am not sure I have seen the females.

Thank you!
I'm going with male unless I hear otherwise, then.
