Caddisflies – Sculptors of the Stream Bed
Description
Caddisflies are an important group of freshwater insects, living in streams, pools and ponds as larvae, emerging for only a brief period as adults, for the reproductive stage of their lives.
Caddis larvae spin silk and use this to construct their remarkable transportable cases from sandgrains, small stones, sticks and other bits of plant material, depending on the group.
A few members build fixed retreats rather than movable cases, and a few are free living. They play an important role in freshwater ecosystems, being sensitive to pollution, and they provide an important source of food for fish.
This talk introduces you to some of the amazing members of this insect group, showing some of the intricate cases that they construct.
