    Small, overlooked, and rarely detected spring species; but likely more commonly detected if people looked for nest sites and observed bees at each species’ favorite food plants.
    Field Marks: ♀♂Small size. Hair, largely absent. Face, wider than long. Wings, while often difficult to see, these species have only 2 submarginal cells. Abdomen, no pale hair bands/patches or pale markings of any kind. ♀Integument, including face, entirely black. Note: face has narrow slits (foveae) above antennae parallel to compound eye, but these are difficult to see without a microscope or high-res photograph. ♂Clypeus bright yellow or mostly bright yellow, remainder of bee all black, with the exception of the ends of the legs (tarsal segments) and portions of front tibia with pale markings.
    Flight Season: Spring
    Size Relative to Honey Bee: 0.5X
    Position of Wings Feeding on Flowers: Completely overlapping
    Location of Pollen Carrying Hairs: Hind tibia and basitarsus
    Similar Genera: Hylaeus - ♀Face, yellow/white markings between eye and clypeus. Carries no external pollen. ♂Face, entire lower face often yellow/palewhite. Calliopsis - Markings quite different. Pseudopanurgus and Perdita - Flight periods do not overlap, both out only in the fall. Most of the Other Genera that are Small Black Bees - Have 3 submarginal cells and noticeable, though possibly restricted, patches/bands of pale hairs.
    Nest: Ground, flat, open bare soil. P. polytrichus and P. potentillae are known to aggregate their nests.
    Flowers: Forbs and low shrubs
