trying to identify this strange bug
My 6 yr old discovered this “pupa” while on vacation at her grandmother’s in the BC interior. She was on a creek at the time. Here is a photo.
This is a Caddisfly Larva. Adult Caddisflies resemble moths. The larvae are aquatic and are called Caddisworms. Many species construct portable cases around their bodies which later become pupal shelters. Sticks, small pebbles and other materials can form the basis of the case. Each species has a distinct type of case with specific building materials.
