Asilidae
I suggest that you move this and all the other fine images of robber flies from ID request to the family page(or even genus of which you are certain), in this way if a specialist comes along he is more likely to find them and comment on them. The images are so clear that they should be IDed to species.

A particularly nice series
Love those eye shots!

yes, and the legs too!
could you share what camera & lens setup were used, and approximate how big (or what was visible) in the original photo field of view? I've been struggling to get these kind of close-ups for key features, and the clarity and resolution on yours is just outstanding.

envious,
Tim

Equipment
Camera: Canon EOS 20D single-lens reflex digital
Lens: Canon MP-E 65 mm. macro (1-5X)
Flash: Canon Macro Twin Lite MT-24EX

The photo was taken at 3X. Photography in the 3-5X realm is most exciting, but can be demanding and frustrating! In order to achieve high resolution, larger apertures must be used leading to paper-thin depth of field. The leg photo was taken at f11, sacrificing resolution to improve depth of field. This is acceptable for the size image used on BugGuide. I will send you a copy of the uncropped image via Email. Thanks for your comment.
