Biology: Little is known about the biology of this species, though it is likely eusocial like most other Lasioglossum (Dialictus) Robertson, 1902. Bohart (1941) discussed stylopization and Stresiptera associated with this species; Hopwood (2007) described a cyclops mutant form of this species.

Distribution in Canada: Knerer and Atwood 1962 [ON]; Gibbs 2010, 2011 [ON].

Gibbs (2010: 80) indicated that this species was uncommon in Canada.
