This project is to update information on the distribution and abundance of Ohio dragonflies and damselflies. It is an update from the first Ohio Odonata Survey which ran from 1991 to 2000, and resulted in the publication by the Ohio Biological Survey of "The Dragonflies and Damselflies of Ohio."

The first survey was entirely based up museum specimens, new collections of specimens, and published articles in peer reviewed journals. Photography has advanced greatly since then, and this site will utilize digital photos to add to scientifically collected specimens. less ↑
