First Instar
I just caught these outside my apt on the walls. There were about 20 of them so I nabbed nymphs and 1 adult. These things were lightning fast too.

Wood roach- Parcoblatta lata, I think. At least a winged male and a not winged female. Another could be one also but looks kinda like a Blatta lateralis.... is this a trick question? ;) I am not as familiar with domestic roaches as I would like to be.

 
Wait, gotta be B lateralis. MAinly because they're not climbing out of the container. ;D

 
Wood roaches cannot climb plastic surfaces. I keep them in culture and are non-climbers just like lateralis are. Nymphs are very similar in appearance.

Look here at this one (adult female) and see what you are seeing in the pronotum:

These can be found wild in your area, and B.lateralis are not likely to be found there as they have more of a tendancy to dehydrate where you live, and wood roaches can survive longer dry periods.

Adults AND nymphs. They were collected in Tennessee. I have pictures of them in another thread.

Huh. Mine (as nymphs) wont climb smooth plastic period. Adult females if really agitated seems like they can but run down for cover. The males can climb the sides when I put my hand in and chase them around, but otherwise are not seen on the sides, just in/around the wood and substrate. Very interesting comparison. BTW- mine were collected in north Texas.

Perhaps we're seeing the makings of speciation? :P
