Hydropsychid caddis larvae have hardened (sclerotised) plates on each of the 3 thoracic segments, and gill tufts under the abdomen. Aoteapsyche caddis larvae are distinguished by the presence of fine hairs covering the abdomen, and 7 sets of abdominal gills.
Aoteapsyche larvae are abundant in many stony streams and rivers, and they reach greatest abundance downstream of lake outlets.
They construct filter-feeding nets attached to the streambed to trap drifting particulate food items, including algae and other invertebrates.
- Hard bottom: 4
- Soft bottom: 6
The tolerance values (ranging from 0 to 10) give an indication of which are the sensitive taxa (values of 8 or more) and which are the tolerant taxa (values of 3 or less). For more information see: Indicator species
Aoteapsyche larvae are common in streams of moderate to good quality, so they are not particularly useful as water quality indicators. They have tolerance values of 4 (hard bottom sites) and 6 (soft bottom sites).
