Synonyms and other taxonomic changes
Lasioglossum pilosum sensu lato (sensu auct.) includes L. floridanum, L. leucocomum, and L. succinipenne, each of which was elevated to species status by Gibbs in his revisions of the Dialictus of Canada (2010) and of the eastern USA (2011).
Size
Female: 6 mm. Male 6 mm.
Identification
Distinctive features of pilosum sensu lato include an elongate head, densely punctate scutum, and dense tan hairs covering most of the terga. Lasioglossum pilosum sensu stricto differs only subtly from L. leucocomum. The former averages larger, has slightly denser scutal punctures, and most importantly has a more squared off clypeal projection (as opposed to clypeal corners convergent apically in leucocomum). A good strategy for identifying these bees is to make an initial sort by size and subtle differences in pilosity and punctation, after which structural characters such as the clypeal projection can be verified.
Range
Minnesota to Nova Scotia, south to Georgia. Records of "pilosum" from the SE USA may pertain to L. floridanum whereas those from the western USA may pertain to succinipenne. In the NE USA and eastern Canada both pilosum and leucocomum occur together commonly and must be separated with care.
Season
March to October.
Food
Visits flowers from several families. The Hosts section on its Discover Life species page lists known floral associations based on specimen records and images.
