Some of the illustrations you will see on this page were drawn by Rick Harrington. He is a professional illustrator and a close friend of mine. If you wish to use his illustrations for any reason you must ask his permission first. All of the Illustrations you will find on this page are original or used with permission. Please ask permission before using them Andy Cooper. The Izaak Walton League of America has graciously let me use their images from their Stream Study web site. This web site also has a good set of macroinvertabrate keys.
About the Keys:
Keys are a way of keying in on certain characteristics of an insect. These characteristics can tell you what stage of life the insects in then the order and family the insect is from. To get to the genus and species level you will need an adult insect. While using the keys you must pay close attention to the description and not weight your final evaluation on the illustrations. As these keys grow and you become more familiar with them you will start to understand the difficulties in aquatic insect identification. With this first set of keys you should be able to get to the order of the insect you have found.
Collection of Aquatic Insects:
Please remember it is ILLEGAL to collect aquatic insects from streams in New York State without a permit. If you ignore this warning please be careful not to collect to frequently at the same location it may have serious effects on the ecology.
