When I checked on my two Thread legged bugs last night, they both responded to the light and came up into view. They saw each other. The one with the oval abdomen and no wings (that I can see) walked over to the one with the slender abdomen and wings (my earlier photo that you ID'd), waved back and forth a bit, then attacked it and ate it. I grabbed my camera and took pictures--would like to submit them but I don't see yet how to do that when submitting a comment. The bugs were in a pint sized plastic container with some soil, mulch, leaves with mites on them, and an Antlion larva I think--larger than they were and apparently of no interest to them. Maybe the cannibalization wouldn't have happened in the wild. Are these bugs sexually dimorphic? I think I've seen now that wing development denotes instars, but the little guy that got eaten had prominent structures at the end of the abdomen that resemble the claspers on a male butterfly.

I left my comments here. Some of your photos are clearly showing Empicoris rubromaculatus, but I'm not sure about this one:. Too close and too fuzy to tell.

that I don't know the answer to. I do recommend that you post the photo(s) of one eating the other -- it would be interesting to see. You can post them under ID Request. One thing I wonder is were both bugs really the same species.

OK, will do. Thanks.

That's! Thanks. I'll have to keep my eye out for actual nymphs now. Neat.
