There are thirty species of clubtail dragonflies in Ohio. Most are river species, making the lilypad clubtail (Arigomphus furcifer) different than the others.
Lilypad clubtails have long and slender bodies, approximately two to three inches long. They are an overall dark green, striped with black. As the name suggests, lilypad clubtails prefer to land and rest on lilypads. Even their larvae are found on lilypads, often sitting on one for the final molting process before becoming an adult. They feed primarily on insects.
Lilypad clubtails live along streams and lakeshores in only eight northern and central Ohio counties and are considered uncommon even in those locations.
