Leptogryllus deceptor   (Perkins)

Oahu Deceptor Bush Cricket
(Leptogryllus deceptor)

syn. -


Hawai'i Islands: O'ahu

local name: -

size: (?)

extinction date: (?)

This rather enigmatic species was described in the year 1910 from the hawaiian island of O'ahu.

The whole genus seems to be only barely known and little investigated. But it is known, that related species (Leptogryllus fusconotatus from O'ahu, Leptogryllus nigrolineatus from Maui) live at the leaf bases of leaves of the Freycinetia liana (Freycinetia arborea). Several other species then again seem to be inhabitants of the leaf litter of the forest floor.


In the official international Red List the species is considered extinct in the wild. Its name can be found furthermore  in the Internet in several lists, which deal with animals that are extinct in the wild, but are kept in zoos for the purpose of species conservation. Most often these lists are copies of copies of ....

However at least In the case of the Oahu Deceptor Bush Cricket this seems to be an error. This species is obviously not kept in any zoo and therefore must indeed be regarded as truly extinct.
