British Insects: the Families of Trichoptera

L. Watson and M. J. Dallwitz

Introduction

This data set is generated from a DELTA database (Dallwitz 1980; Dallwitz, Paine, and Zurcher 1993). It currently comprises a preliminary, interactive treatment to family level of the adults and larvae, based on descriptions prepared mainly from Mosely’s (1939) account and Hickin’s (1952) keys, supplemented from Mosely and Kimmins (1953) and the usual textbooks; but with expert input, it could readily be improved and extended to the genera and species, and also (cf. Hickin, 1952) to the pupae. The nomenclature is aligned with the Steel et al. (1964) update of the Kloet and Hincks Check List.

Curtis is credited with the original taxonomic descriptions of 7 of the Caddis Fly genera and 37 of the species recognised in modern checklists, many of which can be seen in the scans accompanying this data set; and the description of Agrypnia pagetana (see B. Ent. 540) contains generic keys to the larvae and adults. The latter, which Curtis attributes to M. Pictet, utilizes several of the characters featuring prominently in modern classifications and keys.
