Waugh and Wirth (1976) describe larval habits:
The larvae of
Dasyhelea are usually found in aquatic to semi-aquatic habitats. Larvae have been collected in sap oozing from trees, wet bark, and tree holes. Larvae have also been found in small, shallow bodies of water such as puddles, springs, ditches, and marshes, in moss, decomposing plants, moist soil, etc. In larger bodies of water larvae are found in blanket algae or on plants near the margin. Some species are found in extreme conditions such as rock pools, thermal water in hot springs, or in water with high mineral content. Most larvae spin tubular cases in the last instar.
