Two adult males I measured were about 25mm from head to wing tip.
I checked the median segment and the first abdominal segment underneath the wings of one dead adult male of these, what I called "Black Divisa" and it looks like it is a P. pennsylvanica. So these are not P. divisa. Sorry for my mistake. I noticed that my P. virginica and this female P. pennsylvanica carried their oothecae, after tilting it (Parcoblatta carry their oothecae stuck to the tip of their abdomens side ways so that the ootheca side is touching the ground, while being laid the ootheca's bottom is toward the ground as you can see in the picture of the female Parcoblatta virginica to the left.), the top part of the ootheca pointing toward the right side. She has laid another ootheca on June 4th 2014. Her ootheca has not turned to the side yet in the photos below because the ootheca is being laid, she will turn the ootheca to the side not too long after the ootheca comes most of the way out. I also found the ootheca that was missing in the container. The side Dorsal
Here are pictures and a video I took today of a few of my P. virginica. P. virginica are easy to keep. They will chew on my skin and so could be aggressive and eat other roaches while molting. Video of Parcoblatta virginica adultsHere are some pictures of Parcoblatta divisa and Parcoblatta lata I have caught in North Carolina. Those two species were quite common when I looked for them. They were inside old pine wood stumps that you could brake with your bare hands. Also I found many under bark of not so old pine stumps. I found some under the bark of dead pine tree trunks up so high I could just barely reach the roaches even if I used a long stick (I used the long stick to peel the bark off so that the roaches would jump or fall to the ground). Most of the P. divisa I had died and many P. lata also died probably because of my lack of care. They might need a little dry conditions to live well. With the P. divisa and P. lata I found one type of roaches that could be P. divisa, but is slightly different. I am wondering if it is a different species. You can see pictures of these species and also some other animals here:https://www.facebook.com/media/set/?set=a.1477415722480719.1073741883.100006369157688&&l=7eba8b1567 https://www.facebook.com/media/set/?set=a.1474331186122506.1073741879.100006369157688&&l=5800033dee https://www.facebook.com/media/set/?set=a.1465356940353264.1073741872.100006369157688&&l=e9926a5a7c Male nymph P. divisaAdult male P. divisaNymphs of P. lataUnknown species of roach (Is Parcoblatta pennsylvanica) I have a friend in Alabama that has caught roaches that seem like the same type as these unknown roaches I am catching. He thought they could be a variation of P. pennsylvanica. But after one of his males molted to adult he checked the median segment and he says they are like P. divisa. I am not so sure if they are the same species. I have not checked the median segment of the males of my unknown roaches. I have one female of the unknown roaches. Most of the P. lata and P. divisa and these unknown roaches were male. I sexed them by looking at the underside of their abdomens. All of the males of the unknown roaches are dead now. The one female is energetic still though. She was with the males for sometime, so I think she is mated. I was unable to see if the male of the unknown species would try to mate with the females of the P. divisa because the males of the unknown species died before any females of the P. divisa became adult. I have not yet got a female P. divisa to adult (they died and they were not very close to becoming adult when the males of the unknown species died). She laid one ootheca. I am not all the way certain because I did not see the ootheca and I could not find it, but she got much more skinny, so she had to have laid an ootheca. I am keeping the container carefully to not shake the dirt that could cover the ootheca I could not find. I moved the female to another smaller container so that I could easily find the ootheca if she laid another. As nymphs these roaches were fast which made it hard to photograph them and their legs would brake off easily if I tried to hold them. The adult males would fly. Here are pictures of these roaches and comparison of the unknown roaches and P. divisa. I am sorry for these bad photos: https://www.facebook.com/media/set/?set=a.1490314724524152.1073741885.100006369157688&&l=59e3ef4c52 Adult femaleAdult maleMale sub-adult nymph and P. divisa sub-adult nymph on topPre-sub-adults nymphs with one P. lata nymph on topOne of the unknown roaches adult male and two adult male P. divisaNotice the size difference. The adult male unknown roach is larger and darker in color than the P. divisa. They were also darker and larger in size when I compared both species as nymphs which makes sense. The adult male P. divisa I had varied in color but none were near as dark as these unknown roaches. The adult males of the unknown roaches did not vary very much in color. The friend in Alabama has his P. divisa larger than these unknown dark colored roaches. His P. divisa are captive bred and he feeds them good food with probably a lot of protein. He says the wild P. divisa are smaller than his captive bred ones. He has not captive bred these unknown roaches. If he did breed this type of roach they could turn out bigger than the captive bred P. divisa. I wonder if he compared the wild P. divisa he has in his area with these unknown roaches.
