The Wingless Insect Key can be used to help identify such creatures as Proturans, walkingsticks, silverfish, and diplurans.





Our fourteen point Wingless Insect Key can assist in identifying a winged insect. Beginning with Question #1, determine which statement ("a" or "b") is true for the insect in question. From there, simply follow the directions at the end of the true statement until you are finally given the name of the Order your insect belongs to. From there, visit our list pages to specifically identify your insect.
