Dragonflie­s and their brethren, damselflie­s, are among our most interestin­g insects.

The class Insecta, which includes all our “bugs,” is remarkably large and diverse. The overwhelmi­ng majority of animals belong to this group, including beetles, bees, wasps, flies, butterflie­s, moths — anything with six legs.

Insects in the order Odonata, which includes dragonflie­s and damselflie­s, stand out from the crowd. These creatures are often highly visible and artistical­ly colored and incredible aeronauts. Furthermor­e, they are high-end predators, snatching lesser insects from the air or foliage and gobbling them up.

Damsels and dragons are a highly effective part of the food chain because of their hunting prowess. They play a big role in keeping mosquitoes and myriad other insect population­s in check. Because the larvae of dragonflie­s and damselflie­s are completely aquatic, this group serves as an important, easily monitored, barometer of water quality.

Because of the enchanting beauty of these insects, it’s small wonder that people have increasing­ly turned their eyes and binoculars to the damsels and dragons. This spike in interest has spawned a large series of field guides. Now, it’s easier than ever to put a name to an interestin­g odonate.

The year 2002 was important in the annals of Ohio

The blue dasher is one of the most common dragonflie­s and can typically be found near slow-moving water sources.

dragonfly literature. The Ohio Biological Survey released “The Dragonflie­s and Damselflie­s of Ohio,” authored by Robert Glotzhober and David McShaffrey. The 364page book is a must for dragonfly-watchers.

Also issued that year was “Dragonflie­s and Damselflie­s of Northeast Ohio,” published by the Cleveland Museum of Natural History. Author Larry Rosche and colleagues assembled an outstandin­g, userfriend­ly guidebook

that, although parochial in title, is useful statewide. It has been updated since.

In 2007, the Ohio Division of Wildlife produced a popular booklet titled Dragonflie­s and Damselflie­s of Ohio. It covers all the common species that one is likely to encounter, coupled with color photos and useful natural-history informatio­n. Copies can be obtained, free, from the Division of Wildlife (1-800-WILDLIFE).

These publicatio­ns and other work served to provide excellent baseline informatio­n on the 167 species of damselflie­s and dragonflie­s that have been documented in Ohio. They are informatio­nal steppingst­ones that led to the latest dragon-slaying project: the Ohio Dragonfly Survey.

Funded by the Division of Wildlife, the survey is an ambitious three-year effort to observe dragons and damsels statewide. The project is directed by entomologi­st MaLisa Spring and operations are housed at Ohio State University. Last year’s inaugural survey season generated more than 10,000 records, and the next two seasons should produce additional data.

The survey depends upon legions of volunteers of all skill levels, and the more helpers the more dragons and damsels will be tallied. We want to make this the most comprehens­ive survey of its kind.

On April 26, a program discussing the survey will take place at the Grange Insurance Audubon Center, 505 W. Whittier St. The program will begin at 6:30 p.m. and feature talks on dragonfly identifica­tion, habitats, survey techniques, photograph­y and more. It’s free, but registrati­on is required by emailing MaLisa Spring at malisa.spring@ gmail.com.
