The Trichoptera adults RES Handbook covers all species in Britain and Ireland. It is the first volume in the series to be illustrated in full colour throughout.
The caddisflies are a cosmopolitan group of insects whose aquatic larvae are perhaps better known than their moth-like adults. There are currently 199 species known from the British Isles, out of a total of around 1400 species in Europe and over 12,000 worldwide. Although close study of the genitalia is often necessary for species identification, much progress can be made with easily observed characters such as wing patterns.
Handbooks for the Identification of British Insects is a series of books produced by the Royal Entomological Society (RES). Each Handbook provides illustrated identification keys to the insects of Britain, together with concise morphological, biological and distributional information. Accordingly all books contain line drawings, and the most recent volumes feature colour photographs. RES Handbooks are suitable for experienced users. The series also includes several Check Lists of British Insects. Field Studies Council has published RES Handbooks for many years. Many out-of-print Handbooks are now available for free download from the RES.
