Hoplitis are widespread and occur in a variety of habitats from late spring through early summer, although they usually are not especially abundant. Only a few species occur in our region, one of which is exotic and native to Europe. Most Hoplitis nest above ground in stems and other cavities, using their jaws to excavate out excess pith – however, the exotic H. anthocopoides is unique in the northeast in that it constructs free-standing mud nests attached to rocks.

The green eyes and hooked antenna tips of male Hoplitis make them rather unique in our area’s bee fauna. Female Hoplitis are reminiscent of miniature Osmia, but with black integument, green eyes, and thin abdominal hair bands. A few Megachile are also similar in appearance, but have black or gray (not green) eyes. Heriades are generally smaller and more elongate than Hoplitis and also have darker grayish/black eyes.
