Welshman's button caddisfly
Within the silken cases constructed in its larval stage, welshman's button caddisfly is a master of underwater camouflage, intricately weaving debris from its freshwater habitat into its shelter. As an adult, it only lives for a few weeks, during which it doesn't feed, due to its atrophied mouthparts, and dedicates its time to reproduction. With an aquatic larval stage providing crucial ecosystem services as a detritivore, it contributes to the health and clarity of its freshwater ecosystem.
