For identification and information retrieval, you need the program Intkey and data files. You must download and install Intkey first (see below). It is recommended that you install the current version of Intkey as earlier versions will lack some features.

You must have Windows 95/98/ME, NT or 2000. Using these platforms, Intkey can read the data files from the Internet, and afterwards save them on your hard disk if you wish.

Netscape does not work so please use Microsoft Internet Explorer.

If you are unsure how to use the program, go to "How to use Interactive Keys"

DELTA from CSIRO Division of Entomology

The DELTA format (DEscription Language for TAxonomy) is a flexible method for encoding taxonomic descriptions for computer processing. It has been adopted by the International Taxonomic Databases Working Group (TDWG) as a standard for data exchange. DELTA-format data can be used to produce natural-language descriptions, interactive or conventional keys, cladistic or phenetic classifications, and information-retrieval systems.
