Life history and distribution of the Arctic pseudoscorpion, Wyochernes asiaticus (Chernetidae)
The Pseudoscorpiones are a remarkable yet understudied order of arachnids. The northernmost species in North America, Wyochernes asiaticus (family Chernetidae), occurs under rocks beside rivers or creeks and can be found above the Arctic Circle in Canada. In North America, the species is limited to...

In North America, the species is limited to the northwest, although its global distribution includes parts of Asia. It is presumably a Beringian species with quite specialized habitat affinities. I report on some life history traits of this species, based on examination of nearly 600 specimens from 16 localities in the Yukon and Northwest Territories. All life stages were collected.
