Biology

This species is a social parasite, and hosts include other Lasioglossum, subgenus Dialictus, though the specific host(s) are unknown. Gibbs (2010, 2011) indicated that this species was uncommon, though it is likely the common parasitic Lasioglossum collected. Gibbs (2010) incidcated that no Canadian records were known, though Gibbs (2011) records it from Ontario.
