Immature Stages of Sisyridae
Detailed information on immature stages of Sisyridae is being acquired. However, Clausen (1940) noted that the larvae of Sisyra fuscata F. are entire aquatic and suck out the body fluids of freshwater sponges. These larvae are distinguished by having paired, jointed gills on the venter of the first 7 abdominal segments. Eggs are laid in clusters, covered with a web of white silk, upon foliage or other objects that overhang the water.
