Explanation of Names
Greek coelia 'belly' + oxys 'sharp'(1) (refers to the sharp ovipositor and tapered female abdomen)
Numbers

Size
ca. 7-10 mm
Identification
Abdomen conical, pointed in female, armed with teeth or spines in male(3); lack pollen baskets under abdomen, otherwise resemble a Megachile
Range
worldwide [map(2)]
Habitat
Seen at flowers in fields, etc.
Season
Typically Jun-Sep in NC(4)
Food
Adults take nectar at flowers. (They must be eating for themselves, because they do not provision a nest.)
Life Cycle
Cleptoparasites, usually of Megachile (other hosts known outside our area). Using their sharp abdomen, the female breaks into Megachile nests (and removes eggs?) laying its own eggs on the provisions (stored pollen)(5)(6)
