Bagworm larva build protective cases, in which they will pupate, around themselves, and are frequently found on objects (houses, fences, walls) other than evergreen trees and shrubs. The flightless females never leave the larval case. Males, which are not often seen, have a very long, flexible, tapered abdomen with an extendible apparatus for insertion through an opening in the larval case. By this means a male can fertilize a female whom he never sees. The young larva eat their way out of the case in which they hatch to disperse and start the case-building cycle over again. Males emerge from the pupal case fully scaled, but the wings become denuded almost immediately. This male buzzed its way around the mercury vapor lamp, its wings vibrating at the rate of many dozens of times per second, making a very audible humming sound. In its hyper state it bulldozed a Giant Hornet and many other insects away from the light until I captured it in a vial. There was a Bagworm Moth at the MV light the next night also, perhaps a return visit by this one.
