Scarce brown sedge (Ironoquia dubia)
This caddisfly is known from two breeding sites. This species breeds in streams that dry up over summer but can also be found in permanent streams, rivers and still waters. They have a short flight period from the middle of September to the first week in October. They will live amongst leaf litter so riparian trees are important to this species as well as deep slow pools where this matter can collect. Threats to this species include pollution, unsympathetic dredging, engineering works and the removal of marginal vegetation and trees.
