Saskatchewan Minor Aquatic Insect Orders:
Saskatchewan Spongilla Flies (Neuroptera)
There are over 4500 species of Neuroptera worldwide. However only one family, Sisyridae, commonly called "spongilla flies" has aquatic species. Only one species, Sisyra vicaria Walker is recorded from Saskatchewan. The life cycle is holometabolous with a number of generations each year. The larvae feed exclusively on the cell contents of freshwater sponges using mouthparts modified into a fine piercing needle-like structure.
Saskatchewan Alderflies (Megaloptera)
The North American fauna of Megaloptera is represented by about 300 species belonging the families Corydalidae (Dobson flies) and Sialidae (Alder flies). Only the latter family is represented in Saskatchewan by a single species, Sialis velata Ross.The life cycle is holometabolous. Larvae of Sialis feed on other insect larvae and crustaceans. The adults are poor fliers and are usually found around the ponds, lakes and streams that are the larval habitats. The adults likely do not feed.
Saskatchewan Aquatic Moths (Lepidoptera)
Only two Lepidoptera families have aquatic stages. Unfortunately, in Saskatchewan very little information is available on the aquatic species.
Saskatchewan Aquatic Wasps (Hymenoptera)
Eleven North American families of parasitic wasps are considered aquatic. In Saskatchewan only a very few records of wasps reared from aquatic hosts have been made. Only members in which the adult females enter the water to parasitize the eggs, larvae or pupae of an aquatic host are considered aquatic. In these cases the wasp larvae are internal parasites. Some wasps parasitize the terrestrial eggs or pupae of aquatic insects. These wasps are either internal or external parasites and are not considered truly aquatic by some researchers.
