Some information on Odonata of the Great Plains States
A Web Page by Roy J. Beckemeyer
based on some charts from "Odonata in the Great plains States: Patterns of
distribution and diversity", 2002, Bulletin of American Odonatology,
6(3):49-99.

Right: The family-level taxonomic make-up of the Odonata faunas
of the states of the Great Plains. The first six bars are the central
states from TX north through ND, the next four NM north through MT, the last
three MO north through MN.
Right: Shading shows the departure (standard deviation from the
norm) of the number of species of Odonata in certain taxonomic groups from the
average for the Great Plains states as a whole.
Shows a general trend for less than average numbers of species
in the north and west.
Right: Biogeographic affinities of the Odonata faunas of the
Great Plains states showing the proportion of Eastern, Northern
Transcontinental, Southwestern + Western, Transcontinental, Tropical, and
Central species groups in each state.
Right: Shading indicates the number of species of Odonata
recorded for each county in the central tier of Great Plains states. This
and all other charts here show info as of 1999, so some counties now have
records where they might be shown here with none, but the general tenor of the
chart remains correct, ande the under-sampled counties remain less than
well-collected. This could serve as a template for planning collecting
trips to fill in knowledge of Odonata distribution in the central Great Plains.
Right: Precipitation isolines for the central tier of Great
Plains states. Average annual precipitation for the years 1961-1990.
