Cariblatta

Looks like a male E. javanica, possibly subadult.

They look like P. divisa to me so I wonder if the scientists got the ID wrong.

The "southern pennsylvanica" was a term I came up for black form of P. divisa that I erroneously thought that they were different strain of pennsylvanica than the northern ones due to their small size, and the fact that the black female I had never produced viable oothecae when she was housed with several divisa (I think this was due to my poor keeping condition). Few days ago, some of the "southern pennsylvanica" nymphs I collected matured into adult males so I checked under their wings to make sure that my ID was correct. When I did that, I realized that these males weren't pennsylvanica, but were divisa so I was able to determine that these "southern pennsylvanica" were actually just a black form of P. divisa.

It might be that your school's internet isn't stable or something. They are feeding on roach nymphs

That's strange. They should be all in same format cause they are linked to FB album of mine.

Can you see them now?

Hatched nymphs seem to be doing fabulous

Looks like you have some Periplaneta brunnea invasion in your neighborhood. lol

That's an interesting childhood experience. I've been stung by them once and it really wasn't a pleasing experience. lol Here's a little progress over the past few weeks Got 4 nymphs to hatch and more are coming on the way.

Search Cydnoides.

Finally! An ootheca hatched

These are most likely to be P. fuliginosa nymphs. P. americana nymphs don't develop those white markings. P. brunnea nymphs are more vibrant in color compare to the nymphs you have in the pic.

Oops. Didn't see this comment. Sorry for late reply. They are pretty compatible in size so it's hard to say. Southern pennsylvanica tend to be smaller than lata though.

Waiting on these guys to hatch. lol

Thank you I'm really hoping that i'll be able to breed these guys and establish a culture in captivity since they are quite rare.

Mine are around 20~30 mm

I would suggest looking up on this page http://bugguide.net/node/view/166

Black ones are nymphs, red ones are newly molted (teneral) adults, and the ones with white wings are hardened adults, and yes, I'm trying to establish a captive bred colony of this species from my wild collected specimens

In a deciduous forest in Montgomery, AL

Beautiful North American assassin.

From Bugs in Cyberspace.

Same here. They were very abundant near the cabin I stayed in

Yep. P. lata is one of the largest Parcoblatta species in eastern states

They can be reared at room temperature?!!! Man....all the people I've talked to claimed that they needed to be kept cold, but I guess their rearing method was wrong.
