These flies are easily recognized by their distinctively narrow, stalk-like (petiolate) abdomens and feathery antennae, with some species displaying bold silver stripes on their thorax. As parasitoids, they play a specific ecological role by developing inside the larvae of leaf-rolling caterpillars, such as those in the family Crambidae.
