Conventional key • Interactive key, including interactive information retrieval • Hints on using the interactive key

The interactive key allows free choice of characters, is easy to use, 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.

Character list •  General morphology of Hymenoptera • Implicit attributes

These descriptions are offered for casual browsing only. We strongly advise against extracting comparative information from them. This is much more easily achieved using the interactive key.

The bold parts in the descriptions are diagnostic descriptions, generated with the aid of Intkey (Dallwitz, Paine, and Zurcher 1995). They distinguish most taxa in at least one respect from the other taxa.
