Hoplitis albifrons argentifrons
(Cresson, 1864)
Silver-fronted Small-Mason
Hoplitis albifrons argentifrons is a of in the Megachilidae, native to North America. As a member of the osmiine bees, it is a solitary that constructs nests in pre-existing cavities. The subspecies designation indicates geographic variation within the broader H. albifrons . Like other Hoplitis species, it contributes to pollination services in its native range.

Identification
Distinguished from other Hoplitis by the silvery or white front () referenced in both the and subspecies epithets. As a subspecies of H. albifrons, it shares the general of small to medium-sized mason bees with a somewhat robust build. Precise identification to subspecies level requires examination of facial coloration and other subtle morphological characters.
Distribution
Recorded from North America, with specific occurrence documented in Vermont, United States. The broader H. albifrons occurs across much of North America, but this appears to have a more restricted northeastern distribution.
Diet
As a member of Megachilidae, females collect pollen and nectar from flowers to provision nest for their larvae. Specific floral associations for this have not been documented.
Life Cycle
Solitary lifecycle typical of osmiine bees: individual females construct nests in pre-existing cavities, provision with pollen and nectar, and lay before sealing chambers. Development progresses through egg, larval, and pupal stages before .
Behavior
Solitary nesting ; females work independently without colony structure. Males may aggregate near nesting sites.
Ecological Role
of flowering plants in its native range; contributes to function through pollen transfer.
Human Relevance
Contributes to native diversity and associated pollination services; no specific documented economic use.
