Birth of Cockroaches

29 June 2012
Many people may be grossed out by pictures of cockroaches, or the thought of cockroaches flying around us. That is especially true for those found in our urban homes. However, many of us lose the fear when we encounter cockroaches in the jungle, as they are in their natural habitat and do not scramble/fly as quickly as those found in urban areas.

I always thought that all cockroaches laid eggs in egg cases with rows of eggs. It seemed true whenever I found empty cockroach egg shells, much to my dismay. This video however, shows a cockroach giving birth to live young!

Seems that certain cockroaches are ovoviviparous, which means that the young roaches grow in the egg case (ootheca) while still inside the mother’s body, and the mother gives birth to live young. (ref: How Cockroaches Work)
