Bee Flies or humble-flies is the more common name for a family of flies, known scientifically as the Bombyliidae. Some adult bee flies are very important pollinators, feeding on nectar on pollen it can sometimes be easy to mistake them for a bee. The larvae of bee flies are nest parasites or parasitoids, which means that it relies on another insect or a host to survive. This usually results in the death of the host. Bee flies tend to choose ground-nesting and solitary bees as hosts by flicking their eggs into the nests.
