Information on how to identify insects and other invertebrates. The Amateur Entomologists' Society provides information and two different identification services, one is for members of the society and the other is for non-members.
The following documents have been used as reference materials for an insect classification course offered at the University of Florida. They emphasize Florida fauna and usually include the most commonly encountered families. If you use these keys please note they may not always work for your area, BUT with this advisory note please feel free to use as needed. I will add more keys to this page in the future so please check for updates.
