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. With this first set of keys you should be able to get to the order of the insect you have found. Hopes are to have a full set of keys identifying the families of common aquatic insects ovewr time.
