HYMENOPTERA, (Sphecoidea), Sphecidae (Larrinae) --  <Images> & <Juveniles>


          All of the American genera of Larrinae are ground nesting but one extralimital genus is known to nest in twigs. The North American species prey upon various Orthoptera. However, no prey preference has been reported for our single species of Prosopigastra; in Europe some species of the genus prey upon Hemiptera and Homoptera. One extralimital genus preys upon lepidopterous larvae.
