Range
Cosmopolitan, except for South America where a complex of related species replaces it
Habitat
"Breeds in shallow water on the margins of the lakes." -- Hauber 1947

"Larvae are found in marshes, vegetation-choked, eutrophic ponds and lakes, and the sluggish portions of streams and rivers, where they swim around in their hydroptilid caddisfly-like silken cases."(1)
Remarks
Some European populations are parthenogenic.
