NWT snails 1

Cochlicopa lubrica & Pupilla hudsoniana

This post begins a series that will cover the land snails of the Northwest Territories, Canada.

Cochlicopa lubrica. Waiting for the rest of the group to finish, and scratching around in the hope to find something, I found this specimen, one of several, around the roots at the base of a tuft of grasses, in a grassy/sedgy swale parallel to the Fort Smith Hwy 5 but also on the highway’s shoulder.


Pupilla hudsoniana. Among the small pupilloids in the NWT is P. hudsoniana. Until recently, this species has been called Pupilla hebes (e.g., Forsyth 2004), and before that P. muscorum of some authors.  A calciphicole (or calciphile), this species is probably common along the Hay River. This specimen was from a dry slope in leaf litter and broken limestone along the river.
