He was stuck between two leaves and I know I didn't intentionally add him to the tank. Mature larvae can grow up to sizes around 25 mm (fixed nets may be huge in comparison to the size of the larvae). The nonaquatic adults are eaten by birds, reptiles, and other land predators.

Adult length: to about 1 inches; larvae (with case): frequently to 1 inch. The larva attaches itself to some underwater object and begins secreting its outermost layer an opaque white casing that is called the exuvia. A new fly then emerges from this casing and climbs out of the water. High Performance Marine and Terrestrial Bioadhesives and the Biomedical Applications They Have Inspired.

Others are predatory, feeding on aquatic invertebrates and other small prey they can subdue. Adult caddisflies are mothlike. Thanks for joining the discussion. abdomen with dents and tufts of gills; strong prolegs bearing claws; large mandibles; sclerotized labrum (upper lip) oval in shape; second and third thoracic segments lack hardened plates Fascinating, both about the artist and his work and what he's done in his aquarium, and about the caddisfly larvae's creations in the wild as well. The .gov means its official. Net-spinning larvae are apparently territorial and defend space around their retreats from other competitors.
