Surber samples of hydropsychid Trichoptera larvae were collected over two seasons of water flow from a large reservoir spillway in Obafemi Awolowo University, Ile-Ife, southwestern Nigeria. The Trichoptera fauna was made up of two genera, Cheumatopsyche and Amphipsyche, which closely associates with the moss Fontinalis (Bryophyta).The density of larvae was found to increase with the occurrence and bloom of moss. The changes in density of larvae were discussed with reference to the resources provided by the moss and possible life cycle strategies adopted by the caddisflieswhich enables them to survive in the unstable habitat.
