Death's head cockroach

Death's head cockroach

Blaberus craniifer

A species of Blaberus, Also known as Deathshead cockroach

Embodying a flattened, oval body with a shield-like pronotum covering its head, death's head cockroach is distinguished by its striking, mottled brown and dark coloration that effectively camouflages it within its leaf litter and woody habitat. Remarkably, the young are viviparously born, rather unusual for insects, and undergo gradual metamorphosis, eschewing the pupal stage to directly morph into winged adults, equipped with a pair of elongated antennae that serve as exquisite sensory tools.

Life Cycle of Death's head cockroach
Egg The development of death's head cockroach begins with an oval-shaped egg. These eggs are usually clustered together in a protective casing known as an ootheca. The color and size vary, but they are typically small and blend with the substrate to avoid predation.
Nymph Upon hatching, the nymph of death's head cockroach resembles a miniature wingless adult. As it grows, it periodically molts, shedding its exoskeleton to accommodate its size increase. Each molt can bring slight changes in coloration and the gradual development of wing pads.
Adult Emerging from the last nymphal stage, the adult death's head cockroach has fully developed wings and reproductive organs. The body is larger, harder, and distinctly colored, often with more pronounced patterns than in the nymphal stages. Adults are focused on mating and dispersal.
