COLEOPTERA, Phalacridae --  <Images> & <Juveniles>


          These are called the "shining flower beetles," which are common on goldenrod flowers and other composites.  Their larvae develop in the flower heads.  Eustilbus apicalis Melsh is a common predator of the pea aphid, Illinoia pisi Kalt. in Wisconsin.  These beetles were especially abundant in alfalfa fields where younger aphids were most frequently attacked (Fluke 1929).
