Princisia vanwaerebeki
A wingless giant endemic to south-eastern Madagascar and among the largest of all cockroaches. Males are fringed with golden yellow along the abdomen, while females are black with a bluish sheen. The validity of the genus is debated.
Princisia vanwaerebeki is endemic to south-eastern Madagascar and is the only species in the genus Princisia. It grows to 5.6-10 cm, with the largest specimens usually male. The genus honours the entomologist Karlis Princis and the specific name the helminthologist Daniel van Waerebek of Antananarivo. Males often have a fringe of golden yellow along the abdomen, while females are mostly black with an odd bluish sheen. The notch at the front of the pronotum used to define the genus also occurs in other species including G. portentosa, so whether Princisia is a valid genus remains debated. Care matches G. portentosa closely, though keepers describe this species as a little more demanding. Keep at 24-29 C; all life stages climb glass, so a sealed lid is required.

Vegetables, fruit, grains, prepared insect food, dried hardwood leaves
Keep at 24-29 C. Not fussy about air humidity, but extreme dryness causes moulting failures.
All life stages climb glass, so a sealed lid is essential. The species grows large, so give ample vertical surfaces of bark or egg crates.
Combine vegetables and fruit with grains or prepared insect food, and add dried hardwood leaves.
No venom and no biting. When disturbed it hisses by forcing air through its abdominal spiracles.
Care is close to that of G. portentosa but this species is described as a little more demanding. Do not house it with related species, to keep lines separate.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
The ideal temperature for Giant Hissing Cockroach is 24〜29℃. Avoid sudden temperature changes and maintain a stable environment.
The average lifespan of Giant Hissing Cockroach is 3-5 years. With proper care and nutrition, they can live a long and healthy life.
Giant Hissing Cockroach typically reaches 5.6-10cm as an adult. Size may vary depending on care conditions and individual genetics.
