Species Notes

The ♂‚ of this species was described by Mitchell (1960).

The DNA Barcode Index Number (BIN) for this species is BOLD:AAC7048.

Little is known about the biology of this species, though it is likely eusocial like most other Lasioglossum, subgenus Dialictus. Gibbs (2010) indicated that this species was uncommon in Canada. Bohart (1941) discussed stylopization and Stresiptera associated with this species; Hopwood (2007) described a cyclops mutant form of this species.
