Hissing Cockroach Nymph
Gromphadorhina portentosa (nymph)
A young Madagascar hissing cockroach lives hidden in damp leaf litter, under bark, and inside rotting wood on the forest floor. It feeds mostly on decaying plant matter, fallen fruit, and other soft organic debris. The nymph is smaller and softer-bodied than the adult, relying on hiding, flattening itself into crevices, and gradual molts as its exoskeleton hardens. Even at this stage, air forced through breathing openings can produce a defensive hiss.
