Male Nauphoeta cinerea

They come out from under the egg crates at night and are loud so I guess they are moving around a lot more than during the day. The males chase the females at night. The males attack each other. I used to have a male that did not form properly and was much smaller than the others and he was chased by other males a lot. He had to stay on top of an egg crate day and night and at night he would be chased because that is when they come out. Oh, and that thing he was after is a molt of a sub-adult Lobster Roach.
