Insects of Britain and Ireland: the genera of grass moths (Pyralidae-Crambinae and Schoenobiinae)

DELTA home

L. Watson and M. J. Dallwitz


This data set is generated from a DELTA database (Dallwitz 1980; Dallwitz, Paine, and Zurcher 1993), and is an extension from the accompanying Families of Lepidoptera package. At its present stage of development, it largely amounts to an automated, interactive version of data from Meyrick’s (1927) descriptions and keys, re-assigned to the genera recognised in the 2000 edition of Bradley’s Check List, and supplemented with information from other sources listed in the References (notably the 1952 and 1986 treatments of Beirne and Goater, respectively). The taxonomic assignments of larval foodplants conform to our Families of Flowering Plants Intkey package, and are up to date. In addition to the plates from Curtis’s classic British Entomology, the illustrations mostly represent scans of the nice plates in J.H. Leech’s 1886 treatment of British Pyralides, supplemented by less satisfactory ones from Barrett’s 1907 treatment and a few photos. We also include scans of Hubner’s illustrations (1796-1813) of the numerous species and 6 genera of Pyralidae-Crambinae and Schoenobiinae first described by him, referring them to binomials in current use (see the accompanying document for detailed interpretations of his legends).

The interactive package needs extending to species level to be genuinely useful, and organization under the DELTA system renders it readily accessible for that purpose as well as for routine corrections and improvements. Informed criticism and constructive input are of course welcome, and will be appropriately acknowledged. Alternatively, the complete DELTA data set can be donated if required for teaching purposes, or to any professional or amateur entomologist or organization interested in developing it further.
