Insects of Britain and Ireland: water beetles |
This contents page, the keys, and the descriptions were generated automatically from a DELTA database (Dallwitz 1980; Dallwitz, Paine, and Zurcher 1993).
Conventional key • Interactive key, including interactive information retrieval • Hints on using the interactive key
The interactive key is easy to use, allows free choice of characters, and can lead to correct identifications in spite of occasional errors. It can display all the illustrations, full and partial descriptions, diagnostic descriptions, differences and similarities between taxa, lists of taxa exhibiting or lacking specified attributes, and distributions of character states within any set of taxa.

The bold parts in the descriptions are diagnostic descriptions, generated with the aid of Intkey (Dallwitz, Paine, and Zurcher 1995, 2000). They distinguish most taxa in at least two respects from the other taxa.
We advise against extracting comparative information from the descriptions. This is much more easily achieved using the DELTA data files or the interactive key. See also Guidelines for using data taken from Web publications.
