Giant Burrowing Cockroach (Rhinoceros Cockroach)

Macropanesthia rhinoceros — the giant burrowing cockroach, also called the rhinoceros cockroach — is one of the most extraordinary cockroaches in the world and a flagship species of Australian invertebrate biodiversity. Adults reach 8 cm body length and 35 g body weight, making her the heaviest cockroach in the world (the larger Madagascar hissing cockroach is longer at the wingspread but not as heavy). The species is endemic to dry eucalypt woodland and tropical savanna of northern Queensland, Australia, where individuals dig and inhabit deep vertical burrows up to 1 m below ground surface. The burrows are typically inhabited by a single individual or a small family group and are maintained throughout the species' long life. Diet is exclusively dry eucalypt leaves: the cockroach drags fallen leaves down into the burrow at night and feeds on them over weeks or months. The species is OVOVIVIPAROUS — females retain fertilized eggs inside the body and incubate the developing embryos for 8-9 months before live-birthing 20-30 nymphs. Maternal care continues for several months after birth, with the female protecting and feeding the nymphs in the burrow before they disperse. Adults can live 10+ years (vs. 1-2 years for typical pest cockroaches) — extraordinary longevity for an insect of this size. The species is widely kept as an exotic pet in Australia and increasingly elsewhere, prized for the gentle temperament, slow movement, and exotic appearance. The species is completely harmless to humans (no bite, no venom, no disease transmission) and is not a pest.
