There are almost 200 species of caddisfly (order Trichoptera) in the UK, the aquatic larval stages are widely used to monitor the health of freshwater. Caddisfly larvae are well-known because they make themselves protective cases by spinning together stones, sand, leaves and twigs with a silk they secrete from glands around their mouths. Most larvae live in these shelters, which can either be fixed or transportable, though a few species are free-swimming and only construct shelters when they’re ready to pupate. Some of the families make distinctive cases or have other distinctive features which can be viewed under a microscope.
This course will provide an introduction to caddisflies, their natural history, how to identify the larvae to family level using microscopes and keys and an introduction to species level ID as well as information on how to record caddisflies. Please feel free to bring any specimens you may have along with you to identify on the course.
Please note that this course may involve the use of specimens that have been killed and preserved. This course is intended for adults only so it is not suitable for children.
Steve Brooks has been interested in freshwater insects since an early age. He studied freshwater ecology at the University of Newcastle upon Tyne and freshwater insect taxonomy during a 38-year career at the Natural History Museum (London). He has since retired but continues to take an active interest in all things freshwater. He is particularly keen to encourage amateur enthusiasts to become involved recording and monitoring freshwater insects, especially through engagement in the riverfly monitoring initiative to assess river water quality. Currently Steve is chair of the Riverfly Partnership, sits on the Conservation Committee of the British Dragonfly Society and is a Scientific Associate at the Natural History Museum.
This course is heavily subsidised by the FSC BioLinks Project (funded by the Heritage Fund).
