The two pairs of wings are transparent like glass and are nearly equal in size. The larvae suck insects and spiders. Mantispapagana Fabr. Anterior legs predatory; prothorax much elongated (fig. 467, «, b, r). The larvae, after eight months' lasting, bore their way by means of their sucking forceps into the ovisacs of spiders,- and suck out the eggs and the young. After the first moult, the legs are reduced to short stumps, and the body becomes like a Hymenopteran maggot. When about to enter the pupal stage, they spin a cocoon in the ovisac, and strip off the larval skin in the middle of June. The pupa breaks through the cocoon and moves freely about till it casts its skin and is trans- formed into the winged insect. C'Jirysopa perla L. The eggs have long stalks. The larva; have sickle-shaped suctorial forceps, feed on Aphides and spin globular cocoons. Hemerobius lutescvns Fabr. The larvae feed on Aphides.
