Progressive Bee Fly pictureProgressive bee flies zip around flowers and bask on the hot sand in the heat of summer. The adult flies nectar on summer-blooming flowers, and females search for insect nest burrows to lay their eggs, which they may scatter across the ground or flick at specific targets from above. These flies are known to parasitize robber flies, solitary bees and wasps, and ants, though in truth little is known about bee flies as they've attracted little scientific study. As a component of a healthy ecological web, bee fly larvae consume their hosts in their immature growth stages.
