Pollen mites are a kleptoparasitic pest of Megachilid solitary bees, with Ch. krombeini found with Osmia lignaria of North America, (the Blue Orchard Mason Bee). Pollen mites do not feed on bees, but rather their provisions, and are harmful because they consume the food resources and starve or stunt the developing larvae; there is evidence that ...
