County records provide some idea of the distribution of each species. This page provides links to Excel spreadsheets with Odonata county records from Oregon and Washington as of November of 2005. The tables are based on information compiled and graciously provided by Dennis Paulson (Puget Sound University, Washington) and Steve Valley (Oregon State University).
With Internet Explorer you will be able to view and print these worksheets directly though they may take a few seconds to load. With other browsers, however, you may need to download them. Note that you may manipulate these lists in Excel to focus on particular counties.
