Explanation of Names
from genus Miltogramma, 'painted with reddish lines'
Satellite flies: adult females may trail behind potential hosts at a distance of 15-30 cm, often keeping the distance within a very narrow range as though tethered to the wasp (like a satellite is "tethered" to its parent body)
Identification
Arista usually bare or pubescent, but if short plumose, then hind coxa bare on posterior margin. Coxopleural streak present.(1) (distinguishes from Sarcophaginae)
Food
Larvae of most species feed on prey captured and paralyzed by adult digger wasps (Sphecidae, i.e., Apoidea as used here); the prey may include arthropods from a variety of families and orders
Life Cycle
Kleptoparasites of Digger Wasps (Sphecidae): female flies lay live larvae on the wasp's prey before it is buried, so the prey becomes food for the fly's larvae instead of the wasp's. In some species, female flies larviposit in the entrance of wasp burrows, and the fly larvae wriggle down the burrow in search of food.
