7264.          Hot summer day in the afternoon. I have not seen these flies(?) around before…very docile…   Thanks, Delta, British Columbia. Canada

Number 7264. This is a mating pair of robber flies (Diptera: Asilidae); these are ambush predators on a wide variety of other arthropods, mainly other insects. Robber fly example
