General Status Rank
Rank:

Status Rank Description: 
Despite limited records (4), this species could be more prevalent than records would suggest (see range extent and occurrences). However the records overall are limited and very little is known about this species’ habitat (Griffiths 1998). A conservative assessment would put this species at secure to vulnerable in the Northwest Territories, since although there is no indication that this species is under any threat, it is possible.
