Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Phalangacris alluaudi faces severe threats from habitat destruction due to agricultural expansion and urban development across its limited range in Madagascar. The species' extremely restricted distribution makes it particularly vulnerable to localized environmental changes and human encroachment. Invasive plant species are altering the native vegetation structure that this cricket depends on for shelter and breeding sites.
