The emesine reduviids
This group of critters are of much interest to me. I have a couple publications concerning them. If you still have this specimen I would be happy to confirm its identification. That goes for any of your reduviids, but especially your Emesinae. This one might be Emesaya brvepennis; however, there are a couple of species in this genus and since your in GA, it could be a species less common to North America. Just too hard to tell from a photo.

Hi J.D. Bradshaw,

I would love to send you a specimen for identification. I found 3 of these on Catalina Island last year, and we have no record of this genus being here.

Sure thing.

Please send them on. You can send them to:

University of Nebraska-Lincoln
Panhandle Research and Extension Center
4502 Ave I Scottsbluff, NE 69361


so let's move it to the genus page

Emesaya? brevipennis(?)
Slater, How to Know the True Bugs, (Wm. C. Brown, 1978), p.131, fig 246, says Emesaya brevipennis is largest of North American thread-legged bugs (up to 37 mm), and the one that usually gets noticed. Not a lot of images on the web, but this one of E. brevipennis does look close:
Oklahoma Biological Survey page on Emesaya brevipennis

This is put forth as a hypothesis! Now I want to watch out for these things.

However, there is also E. brevicoxa, E. banksi, E. incisa, and E. lineata (and E. brevipennis also has three subspecies). Based on my experience looking at these species, at least E. brevicoxa and E. banksi can be difficult to distinguish from E. brevipennis with confidence without a scope. Also, Slater's 1978 publication is great (and a hard find these days); however, I don't recall if it has all of the North American species of Emesaya in it?

Happy hunting! I have found them most frequently under bridges and overpasses and also on rocky, west-facing cliffs and bluffs.

The challenge: They are very, very rarely seen in flight! The couple times they have been reported in flight has been at dusk. It would be immensely cool if someone could photograph on in flight!

i suggest moving it to genus, not species page
[there's no question about genus]

And it has been...
