Orthoptera of Michigan
PDF file, full title: The Orthoptera of Michigan — Biology, Keys, and Descriptions of Grasshoppers, Katydids, and Crickets.

I only see the Acrididae in that link--needs investigation. Color photos of each genus in that volume. Apparently the PDF is only part of the whole publication--too bad.

There is supposed to be a print version, quoting from the web site:
The Orthoptera of Michigan, Biology, keys, and descriptions of grasshoppers, katydids and crickets by Roger Bland. MSU Extension Bulletin E-2815, 220 pp. ISBN - 1-56525-017-6. ordering information is online at:

Grasshoppers of Wyoming and the West
Includes Key to Wyoming Grasshoppers, etc.
Link updated (again) 4 March 2014--see comments below.

Orthoptera Species File Online
From the home page:

"The Orthoptera Species File (OSF) is a taxonomic database of the world's orthopteroid insects. It contains full synonymic and taxonomic information for over 25,000 species and genera (all taxa described prior to 1998) of the Tettigonioidea (katydids and haglids),Grylloidea (crickets), Acridomorpha (locusts and grasshoppers: Acridoidea + Eumastacoidea + Trigonopterygoidea + Pneumoroidea + Pamphagoidea), Tetrigoidea (pygmy grasshoppers), and Tridactyloidea (sand crickets), as well as images and sounds for many species. A database for the Gryllacridoidea will become available in the second half of 1999. This site also includes a searchable database of entomologists working on the Orthoptera."

Phasmids of North America
[cite:383492]
i couldn't find the compiler of the info provided on that page of the herper.com project, but it contains state faunal lists that may prove useful; please let me know if you have an idea of what source[s] those lists are likely based upon and how reliable they are [e.g., the list for TX contains 15 spp. vs. 16 listed in a trusted source(1)]

Texas Walkingstick Information, by Mike Quinn
[cite:383412]
A part of Mike's ambitious Texas Entomology web project, this page provides a TX faunal list (16 spp., 6 genera, 2 families), links to some photos, online resources, and bibliography (with an emphasis on medical aspects)
