NEUROPTERA, Osmylidae -- <Images> & <Juveniles> Description Clausen (1940) noted this as a separate family of
Neuroptera, with only a few species, the adults of which are relatively small. Withycombe (1923) and Killington (1936)
gave detailed accounts of Osmylus fulvicephalus Scop. The larvae are amphibious and probe in mud
with their long, slender mandibles for Chironomus
spp. larvae and other Diptera inhabiting the wet, mossy borders of streams,
etc. Eggs are elongate-oval, somewhat
flattened, with the chorion bearing reticulate markings. The micropyle is knob-like. They are laid in rows on some object near
the water's edge. hatching occurs in
ca. 22 days, and larvae mature the following spring. The cocoon is formed in damp moss, and
adults emerge 10-12 days after. References: Please refer to <biology.ref.htm>, [Additional references
