Yes, cockroach eggs are large enough to be seen. The mother cockroach lays her eggs in what is called a “case” and may contain from 10 to 40 eggs.
The case is about the size of a fingertip and has the shape of a purse or bean. The eggs are not seen individually because they are enclosed in the case.
The case is going to be brown or black colored depending on the species of cockroach. The mother usually lays the case in a warm and moist and dark location, which is best for the development of the eggs.
When the baby cockroach, or nymph, emerges from the case it is colored white, but after exposure to oxygen the nymph quickly turns brown.
