Each instar is progressively more like an adult cockroach.

In some species, this process takes only a few weeks.

Another study suggests that cockroaches have a collective intelligence made up of the decisions of individual roaches.

European scientists developed a robot called Ins Bot that was capable of mimicking cockroach behavior.

As with many animals, cockroach reproduction relies on eggs from a female and sperm from a male.

Usually, the female releases pheromones to attract a male, and in some species, males fight over available females.

In these species, the mother roach carries her eggs around in a sac called an ootheca, which is attached to her abdomen.

The number of eggs in each ootheca varies from species to species.

But regardless of how long the mother and her eggs stay together, the ootheca has to stay moist in order for the eggs to develop. Rather than growing in an ootheca outside of the mother's body, the roaches grow in an ootheca inside the mother's body.
