The Nebraska odonate list has 109 species in two suborders, damselflies (Zygoptera) with 47 species and dragonflies (Anisoptera) with 62 species. Nebraska had been very poorly surveyed prior to 2005 and 63 counties had fewer than 10 records. By 2017 the number of county records had nearly quadrupled, to over 3000 records, the average county total had increased from 9 to 33 and all counties had at least 21 records. An effort was made to collect data more or less uniformly from all 93 Nebraska counties. The areas with intense corn and soybean farming, eastern and southcentral areas, are low in diversity (21-30 species per county), the southeast and western half of the state are higher (31-40 species) and the northwestern and northern Sandhill counties are the richest with more than 50 species per county. The present state list of 109 species represents 12 additions since 1998. Eleven additional species have been reported from the state, but are considered invalid or have been re-identified. This paper presents a short history of odonate study in Nebraska and an analysis of the data for the 109 species recorded in Nebraska to date. Distribution maps by county are included for each identified
Dragonflies and Damselflies of the West is the first fully illustrated field guide to all 348 species of dragonflies and damselflies in western North America. Dragonflies and damselflies are large, stunningly beautiful insects, as readily observable as birds and butterflies. This unique guide makes identifying them easy--its compact size and user-friendly design make it the only guide you need in the field. Every species is generously illustrated with full-color photographs and a distribution map, and structural features are illustrated where they aid in-hand identification. Detailed species accounts include information on size, distribution, flight season, similar species, habitat, and natural history. Dennis Paulson's introduction provides an essential primer on the biology, natural history, and conservation of these important and fascinating insects, along with helpful tips on how to observe and photograph them. Dragonflies and Damselflies of the West is the field guide naturalists, conservationists, and dragonfly enthusiasts have been waiting for. Covers all 348 western species in detail Features a wealth of color photographs Provides a color distribution map for every species Includes helpful identification tips Serves as an essential introduction to dragonflies and their natural history

This research level text documents the latest advances in odonate biology and relates these to a broader ecological and evolutionary research agenda. Despite being one of the smallest insect orders, dragonflies offer a number of advantages for both laboratory and field studies. In fact, they continue to make a crucial contribution to the advancement of our broader understanding of insect ecology and evolution. This new edition provides a critical summary of the major advances in these fields. The editors have carefully assembled a fresh set of contributions from a diverse geographic mix of both junior and senior researchers in dragonfly biology to offer new perspectives and paradigms as well as additional, unpublished data. These include theoretical and applied chapters (including those addressing conservation and monitoring) as well as a balance of emerging (e.g. molecular evolution) and established research topics, providing suggestions for future study in each case. This accessible text is not about dragonflies per se but is an essential source of knowledge that describes how different sets of evolutionary and ecological principles and ideas have been tested on a particular taxon. Dragonflies and Damselflies is suitable for graduate students and researchers in entomology, evolutionary biology, population and behavioural ecology, community ecology, and conservation biology. It will be of particular interest and use to those working on insects and an indispensable reference text for odonate biologists.
Where the eastern and western currents of American life merge as smoothly as one river flows into another is a place called Nebraska. There we find the Platte, a river that gave sustenance to the countless migrants who once trudged westward along the Mormon and Oregon trails. We find the Sandhills, a vast region of sandy grassland that represents the largest area of dunes and the grandest and least disturbed region of mixed-grass prairies in all the Western Hemisphere. And, below it all, we find the Ogallala aquifer, the largest potential source of unpolluted water anywhere. ø These ecological treasures are all part of the nature of Nebraska. With characteristic clarity, energy, and charm, Paul A. Johnsgard guides us through Nebraska?s incredible biodiversity, introducing us to each ecosystem and the flora and fauna it sustains and inviting us to contemplate the purpose and secrets of the natural world as we consider our own roles and responsibilities in our connection with it.
The definitive single-volume fully illustrated guide This is the first fully illustrated guide to all 336 dragonfly and damselfly species of eastern North America—from the rivers of Manitoba to the Florida cypress swamps—and the companion volume to Dennis Paulson's acclaimed field guide to the dragonflies and damselflies of the West. Dragonflies and Damselflies of the East features hundreds of color photos that depict all the species found in the region, detailed line drawings to aid in-hand identification, and a color distribution map for every species—and the book's compact size and user-friendly design make it the only guide you need in the field. Species accounts describe key identification features, distribution, flight season, similar species, habitat, and natural history. Paulson's authoritative introduction offers a primer on dragonfly biology and identification, and also includes tips on how to study and photograph these stunningly beautiful insects. Illustrates all 336 eastern species Features hundreds of full-color photos Includes detailed species accounts, line drawings to aid identification, and a color distribution map for every species Offers helpful tips for the dragonfly enthusiast
