  Unarmed Leafcutter Bee

  Megachile inermis is a solitary leafcutter bee described by Provancher in 1888. Unlike many Megachile species that use pre-existing cavities, this bee excavates its own nesting tunnels in decayed poplar wood. It has been recorded from trap-nest studies in Saskatchewan, Manitoba, and Wisconsin, with a notable male-biased sex ratio in rearings.
