Entomology--Natural History Museum of Los Angeles County
Has pages on Insects of the Los Angeles Basin (a small image gallery), Common Spiders of Los Angeles basin (including image gallery).

Electronic Biologia Centrali-Americana
Digital version of (part of) an important historical work on Central-American biodiversity. Many plates of insects. Takes some hunting to find the plates, but can be downloaded as pdf's and they are beautiful. The original work is from the end of the 19th century, and is in the public domain, but the Smithsonian is asserting copyright to the digital version--they allow educational and personal use.

Oklahoma Wild Things
Lots of excellent photographs by Charles S. Lewallen. Has good identifications of many common or notable Oklahoma insects, including less well-known groups (heteroptera, hymenoptera, diptera). Takes some digging to find images.

Table of contents pages are alphabetical by common name. (Listing by families is not complete.) See the list of alphabetical TOC pages, which includes beetles, lepidoptera, other insects, and spiders. (There are pages on vertebrates too.) The contents pages just list the common name, but the full Latin name is usually listed with the photo.

Florida State Collection of Arthropods
Lots of good stuff if you spend some time digging for it. Here are some highlights:

Gallery of Florida Insects
Links to other online resources

What drew my attention there in the first place were their publications. Best of all, if you install their DjVu viewer you can view many of them online. There are also instructions if you want to order the ones still in print.

AMNH Arthropod keys
Has some printable, dichotomous keys for arthropods with line drawings. Goes into good detail for groups of true bugs, for instance.

Integrated Taxonomic Information System (ITIS)
A searchable taxonomic database for all living things. I just discovered this tonight but I can see it will be extremely useful.

For one thing, I can search for a genus and quickly see where it fits into the taxonomic hierarchy. This will make finding things in Arnett (1) simpler. They also provide common names for most taxa. Another use would be to get a quick check for how many species there might be for a particular genus.

There does appear to be huge omissions. For example, I couldn't find Salticidae (jumping spiders) in there.

Digital Arthropods
A digital field guide to the Phylum Arthropoda. Last updated 2001, but looks fairly extensive. Searchable database with photos and life histories.

The Duke Natural History Society
I just found out about this group when they linked to BugGuide.Net from their online resources page. It sounds like a great opportunity for those in the Durham, NC area. Their online resources page also has many useful links for those of us in the Southeastern US. I plan to mine it and duplicate the useful links on this site.
