The larvae of caddisflies are very useful indicators of water quality, but it is the adults which will be more familiar to many people, especially moth trappers!  This one-day course is designed as a follow-up to the ‘Field ID of Adult Caddisflies’ but can also be a stand-alone course for people wishing to jump straight to using microscopes to identify adult caddis specimens to species level.


The course will provide an introduction to identifying adult caddisflies to species level using microscopes and identification keys. The course will include a short presentation introducing the features used to identify specimens to species level. During the course participants will:

·        Learn about caddisflies and their ecology.

·        Gain experience looking at adult caddis ID features using a microscope.

·        Use an ID key to determine specimens accurately to species level.

·        Know how to take their interest further.


This course is taking place at FSC Preston Montford, please see the course brochure below for more info.

FSC BioLinks courses are highly subsidised thanks to funding from the National Lottery Heritage Fund.
