Reed, C.C. 1996. List of insect species which may be tallgrass prairie specialists. Final report submitted to the Minnesota Department of Natural Resources. 43 pp.
Approximately 728 insect and allied species and subspecies were considered to be possible prairie specialists based on any of the following criteria: defined as prairie specialists by authorities; required prairie plant species or genera as their adult or larval food; were obligate predators, parasites or mutualists of prairie specialist insects; were found in collections from prairie sites but not from nearby woodland sites; were limited to states and provinces in the northern tallgrass region. Lepidoptera, Homoptera and Orthoptera contained the most obligate species, due to the attention given to these orders by prairie entomologists. Selected families of Diptera, Coleoptera, Hymenoptera and Hemiptera will probably be shown to contain numerous specialist species when adequate prairie collections are made. Spiders are also recommended for further collections and study.
