Moved from Thread-legged Bugs to Barce page, as per J.D. Bradshaw's identification and request.

Can someone with more power than I please add this specimen to Barce. I believe that to be correct as it looks to be about 13 mm in length. To be absolutely certain I would need a close up of the tarsi, forelegs, and the tarsal claws. However, the coloration is right and it is a one of the most diverse genera within the Metapterini in North America -- next to Emesaya.

Also, this would improve the generic representation of this subfamily of Reduviidae on BugGuide. :-)

This specimen does not look like Emesaya. Using the width of the thorax relative to the length of the body and the size of the wood grains that it is standing on as a reference, this specimen is much smaller than Emesaya. In fact, my guess is this specimen is about 13-17 mm in length (not the ~45 mm that is common with Emesaya) and probably belongs to the tribe Metapterini and might be a species of the genus Barce. Also, it looks like it is female.

Thanks for all the help!

Robin's right- it's a "thread-legged" bug, a subfamily of Reduviidae. There are a few pictures posted on this site of these critters, but not many.

cheers,

Perhaps it is an assassin. It does not have the "bug eyes" of a Nepid either...

The way it's holding its front legs reminds me of an assassin bug, like the Barce species shown at Cedar Creek.

Looks like a Nepid, or waterscorpion. It is a type of Hemipteran.
The long antennae and lack of caudal filaments seems strange though. I wonder why...
