Largest caddisfly

Caddisflies are best known for their home-building freshwater larvae, which famously construct and live inside protective cases made of silk and then decorated with gravel, sand, twigs, and sometimes even more exotic items such as empty snail shells. In contrast, the adults are small moth-like insects with characteristically hairy wings. The world’s largest species of caddisfly is MacLachlan’s caddisfly (Eubasilissa maclachlani) from Nepal, which has a wingspan of 7 cm (2.76 in).
