Usambara Drumming Grasshopper
The Usambara Drumming Grasshopper, Ixalidium transiens, has not yet been evaluated for inclusion on the IUCN Red List of Threatened Species™, however, it has a provisional assessment of ‘Vulnerable’. It is endemic to the East Usambara Mountains in Tanzania and is a nocturnal species that dwells in the litter layer of evergreen submontane forests. It drums with its hind legs on the substrate to attract females.
The Usambara Drumming Grasshopper is a representative of a species-rich fauna found in the East Usambara Mountains. This mountain area is part of one of the global biodiversity hotspots, the Eastern Arc forests, which are stretching from south-east Kenya to south-west Tanzania. The area is known for its high endemism (53% of the grasshopper species in this mountain block are endemic), which is threatened by deforestation and habitat fragmentation.
Due to the exceptionally high biodiversity found in the East Usambara Mountains, a lot of activities for their conservation have been started. Since 1993, the Tanzania Forest Conservation Group is promoting forest conservation and tries to establish forest corridors in order to reconnect the forest fragments.
