Biology

Little is known about the biology of this species, though it is likely eusocial like most other Lasioglossum, subgenus Dialictus. The species is rare in Canada, only known from a handful of specimens when Gibbs (2010) first recorded it from Canada, with additional recorded recorded by Gardner and Gibbs (2020), who indicated it was one of the most common red-tailed species in western North America.

Distribution in Canada

This species from Alberta (Gibbs 2010) and Alberta and Saskatchewan (Gardner and Gibbs 2020).
