Bee-flies 09 May 2014

I couldn’t resist spending some more time this spring watching bee-flies. I can combine this with a continuing study of a violet oil beetle population in a local meadow. Both of these insects are nest parasites of solitary bees. The oil beetle larva feeds on the pollen collected by the bee whilst the bee fly larva waits for the bee larva to consume its food supply before latching on to its body and sucking it dry!
