Cockroaches are a nuisance for most people especially as they live at home and tend to destroy furniture and books. Most people don’t think of them as a useful addition to the ecosystem. However, did you know that there so many interesting facts about cockroaches? They are actually a good source of protein for birds and several animals that feed on them. Another interesting fact about these insects is their life cycle. They undergo an incomplete metamorphosis going from egg, nymph to adult cockroach. Each stage in the life cycle of a cockroach is slightly different in morphology. As they mature, they tend to develop other features and a much complete structure e.g. the nymph has almost no wings and can’t fly. However adult cockroaches can fly. This page features and interactive online diagram on the stages in the life cycle of a cockroach.

This is a great classroom exercise for children in the following grades: 1st grade, 2nd grade, 3rd grade, 4th grade, 5th grade and 6th grade. In the UK system of education, this is equivalent to science for year 2, year 3, year 4, year 5, year 6, year 7 and year 8.
