| Review (by Malcolm Storey) | A large handbook, with keys to species and comprehensive line drawings. Although at first sight this book makes Caddis look relatively easy, with large clear line drawings of all the genitalia often from several angles, however, in practice, the insects do not much resemble the illustrations. This is said to be because the figures were drawn from dried and distorted specimens. |
