Natural History Photographs


The index files below provide a systematically organized overview of the taxa represented on this site. In principle, the overview is based on phylogenetic principles; however, sometimes I found it necessary to compromise between phylogenetic rigor and usability. In my notes On taxonomy, I reflect briefly on this trade-off. These notes also refer to the sources used to build the index files.

Using the index files to find a taxon can be very laborious, certainly if one is not too familiar with the hierarchical classification of a group. To allow for quick searches on particular species, the user is referred the menubar search field (indicated by the magnifying glass); for more elaborate searches (higher taxa; geographic locations; time of observation; or any combination of these) I refer to the search page. The search facility is built on the index files, which are exclusively built from scientific names. Nonetheless, you can also search for common names in a small sample of languages (English, Dutch, German, French, Norwegian and Swedish). The coverage of taxa in these languages varies from 9% for Norwegian and Swedish to 40% in Dutch.

In the index files below, the numbers in parentheses is the number of species of the pertinent taxon you can here find photographs of. Species names in brown color refer to photos made in Australia. Species names in green color refer to photos of "extended phenotypes," mines and galls; more often than not, the insect itself doesn't show on the photo (e.g., species of the fly family Agromyzidae).
