Coelioxys coturnix
Coelioxys coturnix is a cleptoparasitic bee in the family Megachilidae, commonly known as sharp-tailed bees or cuckoo leafcutting bees. As a cleptoparasite, females do not construct their own nests or provision cells with pollen. Instead, they exploit nests of host bees in the genus Megachile, laying eggs in host cells where their larvae kill the host offspring and consume the stored provisions. The species has been documented exhibiting hospicidal behavior, where the parasitic larva actively kills the host egg or larva.
