The mouth parts are peculiar inthat they are intermediate in formbetween the sucking beak of He-miptera and the biting mouth partsof other insects. Their eggs resemble those ofHemiptera; the larva? and pupa1are active, and in form resemblethe adult, except in the absence of wings. Some speries, also, are wing-less in the adult stage.
