Ecology: Instream habitat: Tasimiid larvae occur in clear, fast flowing, cold mountain streams. They are found on rocks. Feeding ecology: Larvae graze on benthic algae and fine organic particles. Habit: Larvae construct tubular cases from small stones with larger pieces along the sides. Lateral humps on the first abdominal segments help the animal to move across rocks in fast-flowing water. The larva pulls itself partially out of its case and uses the ring of hooks on the humps to cling to the rock surface. Life history: Final instar larvae crawl to the stream banks before pupating and fix their cases under the water’s surface. Collections of these cases can accumulate over time, with several years’ worth of pupal cases layered on top of one another. Tasiagma ciliata does not have a synchronised mass emergence of adults. |
