LEPIDOPTERA, Pyraustidae --  <Images> & <Juveniles>

 

          Dicymolomia julianalis Wlk. preys on eggs of the bagworm, Thyridopteryx ephemeraeformis Haw. in North America (Gahan 1909).  As much as 30% of the bags were found infested, and a single larva consumed the entire egg contents.  The cocoon is spun at the free end of the bag.  Dicymolomia has the normal habit of being a scavenger in the heads of cattail (Typha sp.).  Balduf (1937) believed that this species was not primarily predaceous, but that the eggs are destroyed incident to the preparation of a hibernaculum.
