Triaenodes bicolor

Triaenodes bicolor is a species of caddisfly, belonging to the order Trichoptera. Caddisflies are mothlike insects found near freshwater habitats worldwide. Their larvae are aquatic and play a crucial role in local food webs, serving as a food source for fish. Some caddisfly larvae, like Triaenodes bicolor, are known to swim using specialized legs, while also dragging their protective cases through the water. These cases are constructed by the larvae using silk and materials like sand or debris for protection and rigidity. Adult caddisflies are typically small, with hairy wings, and are often attracted to lights at night.1
