Life Cycle Of Smoky Brown Cockroach

The life cycle of the Smokybrown Cockroach (Periplaneta fuliginosa) consists of three main stages: egg, nymph, and adult.

The eggs incubate within the ootheca, and the development period can last around 40-60 days, depending on environmental conditions.

Nymph Stage: Once the eggs have developed, nymphs hatch from the ootheca. Nymphs are smaller versions of adult cockroaches but lack fully formed wings.

Adult Stage: After several molts, the nymphs reach the adult stage. Adult Smokybrown Cockroaches have fully developed wings and are capable of flying. They also exhibit the characteristic smoky brown coloration, which distinguishes them from other cockroach species. Adult cockroaches are sexually mature and can reproduce.
