Migration
Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Population Biology
Number of Occurrences
Note: For many non-migratory species, occurrences are roughly equivalent to populations.
Estimated Number of Occurrences: > 300
Comments: Taylor (1895) lists specimens from drift of the Red Deer River in Alberta but no other Alberta records can be confirmed, so this record is questionable. In New York, Hotopp and Pearce (2007) report it from 18 counties. It was recently documented in 20 of 82 soil samples and 6 area spot searches of Wind Cave National Park, South Dakota, in 2002 (Anderson, 2005). Schroeder (2008) documented this species from Nelson Co., Kentucky. In Ontario, it is limited to the immediate proimity of Lake Erie and Lake Ontario shores (Essex Co., Halton Municipality, Hamilton Div., Northumberland Co.) (Nekola, 2009).
