Immature Stages
of Osmylidae
Detailed information on immature stages of Osmylidae is being
acquired. However, Withycomb (1923)
and Killington (1936) studied Osmylus
fulvicephalus Scop., and
reported that the larvae are amphibious and probe into the mud with their
long slender mandibles for the larvae of Chironomus
and other Diptera in the wet, mossy borders of streams and the like. The eggs are elongated and oval, somewhat
flattened, with the chorion bearing reticulate markings, and 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 larval maturity is reached the
following spring. The cocoon is spun
in damp moss and the adult emerges 10-12 days later. Please CLICK on picture to view details: References: Please refer to <biology.ref.htm>,
