Critically Endangered
Mahé boulder cricket
Phalangacris alluaudi
Mahé boulder cricket is a grasshopper or katydid in the family Phalangopsidae (order Orthoptera) — Phalangacris alluaudi, recorded as Critically Endangered.
Range and habitat
The Mahé boulder cricket is an insect species endemic to Mahé island in Seychelles. This species of cricket is only found in two localities, the Morne Seychellois National Park and "La Reserve". It is a restricted range species, with an area of occupancy less than 10 square kilometres (3.9 sq mi) and with a very fragmented population.
The problem with many insect populations is that small areas that can rapidly be destroyed by humans, so that even a large population can disappear rapidly.” The IUCN specialist group intends to publish a field guide to identify different species of the order Orthoptera, that includes crickets and grasshoppers. Of the islands of Seychelles to assist local conservationists.

Life history
Song, season, and a named mountain are how many of these insects were split. A silent valley after fire is an empty record.
Life history follows the order: complete metamorphosis in moths and beetles, nymphs in grasshoppers and bugs. This page does not invent a host plant that no source named.
In crisis
The population is assumed to be declining due to the deterioration of its habitat, threatened by the invasion of alien plants species like Cinnamomum verum and Clidemia hirta. Axel Hochkirch, co-chair of the IUCN’s Grasshopper Specialist Group has said, “We have no idea how many individuals exist in total. Insect populations can be quite large in a small area.
