Remarks
Larvae parasitize caterpillars of the drab prominent, which feed on the undersides of sycamore leaves. They "exit from a mature host en masse, move a short distance away, usually less than 2 cm, void their meconium and attach their posteriors to the leaf. Within an hour they pupate and turn black" (Thompson & Solomon 1986). Say (1836) reared the type series from pupae found attached to the underside of a sycamore leaf, but he did not determine what caterpillar they had emerged from.
