Discoid cockroach

Discoid cockroach

Blaberus discoidalis

A species of Blaberus, Also known as False death's head cockroach

Blaberus discoidalis, commonly known as the discoid cockroach, tropical cockroach, West Indian leaf cockroach, false death's head cockroach, Haitian cockroach, and drummer, is a cockroach native to Central America of the “giant cockroach” family, Blaberidae. The adult is around 35–45 mm (1.4–1.8 in) in length, and is tan with a dark brown to black patch on its pronotum. The juvenile is brown with tan speckles, and matures to adulthood in 4–5 months. Adults have wings but are not active fliers, and they can not climb smooth vertical surfaces, simplifying their care in captivity. B. discoidalis is called the false death's head cockroach because of its superficial resemblance to the death's head cockroach, Blaberus craniifer.

Life Cycle of Discoid cockroach
Egg The egg stage marks the beginning where discoid cockroach's development proceeds internally. The eggs are often laid in a protected environment and encapsulated within an ootheca for safety.
Nymph After hatching, the nymph resembles a miniature adult discoid cockroach, lacking mature wings and reproductive organs. Through successive molts, it grows larger, develops external wing buds, and changes color gradually until it reaches maturity.
Adult Emerging from the final molt, the adult discoid cockroach exhibits fully developed wings and reproductive organs. The exoskeleton is harder and the coloration more pronounced. Adults focus on reproduction and dispersal activities.

Habitat Preferences of Discoid cockroach Through Different Life Stages
Eggs of discoid cockroach can typically be found hidden in dark, warm, and humid environments such as under decaying wood or leaf litter. Nymphs, which undergo simple metamorphosis, thrive in similar conditions but may venture out slightly more as they grow, feeding on decomposing matter. Adults, able to fly, often inhabit areas with access to food, such as kitchens or warehouses. To observe different stages, one would search damp, concealed locations for eggs and nymphs and broader areas for adults, with attention to potential feeding sites and the presence of other cockroaches, indicating a suitable living environment.
