scientific name    Bombylius lancifer    

Arid regions with loose soil of the type frequented by ground-nesting bees.

10-14 mm long, 20-24 mm wingspan. Anterior half of wing brown, translucent; posterior half transparent, colorless. Hair with blonde tint. Characteristics shared with other Bombylius species include a slender first antennal segment, long scattered bristly hairs, holoptic males, conspicuously bristled hind femora, and a distinct intercalary vein (Hull 1973).

life history
Very little species-specific information available. The general bombyliid life cycle is described in Marshall (2006). Females coat eggs with a sticky substance in order to gather a protective layer of soil when they are dropped into burrows of potential hosts. First instar larvae actively penetrate host nests, then molt into sedentary ectoparasitoids, a phenomenon known as hypermetamorphosis. Pupae are equipped with rigid ornamentation to assist escape from the burrow. Adults resemble bees as a deterrent against predators, and imitate them behaviourally and functionally by feeding on nectar and spreading pollen.

No specific information could be found. It can be assumed that as parasitoids, the success of the species is dependent on the success of the host or hosts.

diet info
Larvae parasitise solitary ground-nesting bees, adults feed on nectar (Hull 1973).

Nearctic (Hall & Evenhuis 1980).
