Nemobius sylvestris (Orthoptera, Trigonidiidae, Nemobiinae) in North America

Abstract

The wood cricket Nemobius sylvestris (Bosc, 1792) is herein reported in North America for the first time. The species is currently known to be established in the vicinity of Rochester, New York, and Seattle, Washington, indicating two separate introductions. It is unclear when the species was first introduced to the region, nor what its potential ecological effects may be. The presence of this species in the USA was first noted via photos posted to iNaturalist, highlighting the value of citizen/community science platforms in detecting novel introductions.
