Leptogryllus deceptor Perkins

Oahu Deceptor Bush Cricket (Leptogryllus deceptor)

This rather enigmatic species was described in the year 1910 from the island of O’ahu, Hawaiian Islands.

The whole genus seems to be only barely known and little investigated. But it is known, that related species (Leptogryllus fusconotatus Perkins from O’ahu, Leptogryllus nigrolineatus (Perkins) from Maui) live at the leaf bases of leaves of the ‘ie ‘ie liana (Freycinetia arborea Gaudich.). 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 species conservation. Most often these lists are copies of 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.
