Why do you usually find dead cockroaches on their backs with their legs in the air?
Submitted by edwbaker on Tue, 24/11/2009 - 12:02pmProbably because after they die the muscles in their legs contract due to rigor mortis, pulling their legs towards the body and flipping them onto their backs.

If you squash a cockroach will this spread its eggs?
Submitted by edwbaker on Tue, 24/11/2009 - 12:03pmDefinitely not! Cockroach eggs are contained in a case called an ootheca and if this is damaged the eggs inside will die. Some cockroaches deposit the ootheca soon after it has hardened, a few carry it until it hatches, and others incubate it inside their bodies until the eggs hatch.
