Bombylius mohavensis

Evenhuis, 1975

Bombylius mohavensis is a of bee fly in the Bombyliidae, described by Evenhuis in 1975. The Bombylius includes species known for their -like appearance, hovering , and parasitic larval . Members of this genus typically have elongated adapted for nectar feeding and exhibit spring activity patterns. The specific epithet 'mohavensis' suggests an association with the Mojave Desert region.

Distribution

The specific epithet 'mohavensis' indicates association with the Mojave Desert region of North America, though precise distribution records are not documented in available sources.

Seasonality

Based on -level patterns, Bombylius are typically active as in spring. This distinguishes them from related genera such as Systoechus, which tend toward fall activity.

Diet

feed on nectar using elongated to reach deep into flowers. Larval diet is parasitic; related Bombylius are known to parasitize solitary larvae in the Andrena, Colletes, and Halictus.

Host Associations

Andrena - larval for related B. major; inferred possible host based on
Colletes - larval for related B. major; inferred possible host based on
Halictus - larval for related B. major; inferred possible host based on

Life Cycle

Based on -level information: females hover over burrows and flick into tunnels with abdominal movements. Larvae hatch and actively seek host bee larvae, attaching as external and eventually killing the host. occurs in the soil, with emerging the following spring. Some related may pass two winters in the pupal stage.

Behavior

exhibit hovering , particularly males which may defend territories or display for females. Females engage in 'bombing' behavior to deposit into burrows.

Ecological Role

may function as flower visitors and incidental . Larvae act as of solitary bees, potentially regulating . The occupies a position as a secondary consumer in .

Human Relevance

Bee flies are generally harmless to humans and pets. They do not bite or sting. Their parasitic affects solitary bees but not social bees such as honey bees, limiting agricultural impact.
