Robber Flies (Asilidae) 
are 3/4 - 1 1/4 inch long and vary in appearance. Some are quite stout while others are long and slender. The face is usually bearded and the head is hollowed out between the eyes. Adults are predaceous on many kinds of insects and usually capture their prey in the air. Larvae are soil-dwelling and predaceous on such things as white grubs.

Syrphid Flies (Syrphidae)
 are sometimes called flower flies because they are commonly found on flowers or hover flies for their behavior in flight. Most of these flies are yellow with brown or black bands on the abdomen. Some resemble wasps, many mimic bees.







Syrphid larvae are maggot-like and predaceous on aphids and other soft-bodied insects. They have no legs or visible head capsule and are translucent.
