Habitat and Ecology [top]

Habitat and Ecology:It is a rupicolous species, associated with open rock faces, often hiding in clumps of vegetation growing out of cracks in the rock. The surrounding environment is usually moist savannah or montane forest. The larvae develop on rock faces covered by a film of water, where they feed on algae.

Threats [top]

Major Threat(s): Little direct information is available on its threats, but presumably the ongoing loss of forest and woodland habitat might result in a reduction of water seeping over rocks, thus destroying its breeding habitat.

Conservation Actions [top]

Conservation Actions: It occurs in the Mulanje Mountain and Zomba Mountain Forest Reserves. Additional survey work is needed to determine the population status of this species, and to better understand the immediate threats.
