A common caddisfly that breeds in ponds and ditches, including temporary ones. The female lays a blob of jelly containing the egg mass on leaves that overhang water, or where water will be after the Autumn rains. The eggs eventually hatch and the larvae fall into the water where they make flat cases of dead leaves.

Nemotaulius punctatolineatus is the only other UK caddis to lay similar gelatinous egg masses on overhanging leaves but it is confined to blanket bogs in the Scottish Highlands.
