There are several species of Robber Flies that mimic bumblebees; kind of a wolf in bee's clothing.  Unsuspecting insects ignore the "harmless" bee and then get pounced on.  There may be some Mullerian-type Mimicry benefits to the Robber Fly in resembling a bumblebee, but the advantages of looking harmless to other insects is probably more important.
