     Sisyridae = Link 1


This is a small family of "spongillaflies" with just a few genera and species.  There are 6 species in North America, three each in genera Climacia and Sisyra.  The Rs vein in the former has a single fork while the latter has 2 forks located proximad of the pterostigma.  Larvae of Sisyra fuscata F. are entirely aquatic, sucking the body fluids of fresh-water sponges.  The larvae are distinguished by having paired, jointed gills on the venter of the first 7 abdominal segments.  Eggs are laid in clusters that are covered with a web of white silk, on foliage or other objects hanging over the water (Clausen 1940/62).
