Immature Stages of Sialidae
Detailed information on immature stages of Sialidae is being acquired. However, Clausen (1940) noted that in this small family, the larvae of Sialis and several other genera are wholly aquatic and are believed to feed, partially at least, upon other aquatic insects and the smaller animal life present in their habitat. The eggs are deposited in large masses on vegetation over or near the water.
