The Black Fly Hunter

Drawing by Eva Engblom

Common name: Black Fly Hunter

Latin Name: Rhyacophila nubila (Insecta, Trichoptera, Rhyacophilidae)

Areas: The caddis flies Rhyacophilidae are common in many running waters in the northern hemisphere. They can also be found in litoral areas of well aerated lakes.

Info:

In Man and Water Rhyacophilidae are used as indicators of the state of oxygen concentration, since they can not withstand low concentrations.

Rhyacophilidae belong to the most important fish food organisms, but are also utilized by different species of birds.

Most Rhyacophilidae are predators and the species Rhyacophila nubila feeds to a large extent on black fly larvae.
