Caddis adults AIDGAP

FSC Caddis adults AIDGAP is an identification guide to families of adult caddisflies in Britain. Identification goes to species level where possible.

Many moth recorders will have found caddisflies in light traps, but perhaps never attempted identification. Caddisflies are also familiar to fly fishermen, who imitate them with artificial flies.

For people unfamiliar with the group, opening a specialist identification book on caddisflies can seem daunting. So this concise guide is a gentle first step. There is a photo of a representative species, along with useful features such as flight period and wing length.

This caddis adults guide is part of the FSC’s AIDGAP series (Aids to Identification in Difficult Groups of Animals and Plants). The aim of AIDGAP series is to produce accessible keys suitable for non-specialists from age 16+. Although written by specialists, all AIDGAP guides go through field tests in draft form. As with all guides in the series, the Caddis adults AIDGAP underwent extensive testing before publication, by beginners and specialists alike. The author has revised this, the first published version, in the light of the testers’ experience.

Accurate identification of specimens is an important part of biological fieldwork. Although popular groups such as wild flowers and butterflies are well-served, many other groups are neglected. Since 1976, the AIDGAP project has published over 40 straightforward and clearly written identification keys to many different groups of plants, animals and other taxa. In many cases a newly published AIDGAP guide has led to an immediate upsurge in the number and spread of biological records.
