Immature Stages of Raphidiidae
Detailed information on immature stages of Raphidiidae is being acquired. However, Clausen (1940) noted that the eggs are usually laid in clusters in crevices in the bark of trees. The larvae are found under bark, although they also occur in decaying wood, etc. They prey mostly on aphids, caterpillars and other soft-bodied insects. They pupate in an oval cell beneath the bark or in decayed wood. The life cycle covers several years.
