Growth
Cockroaches grow gradually through hemimetabolous metamorphosis. There are three distinct stages in their life cycle that include egg, nymph, and adult. Only adults are able to reproduce and will have wings. Prolonged nymphal stages along with additional molts can sometimes occur in B. giganteus for a number of reasons. One hypothesis is that the absence jostling and mutual stimulation which are found often in colony life could slow the developmental process. In other instances lower temperatures and reduced humidity can lead to delayed maturation and an increase in the number of molts. This is a response by the insect to unfavourable habitat conditions and can also be seen as a predatory response.
