Takeoff and flight sequence of a Common Stonefly captured at 3,200 fps by Dr. Adrian Smith, Head of our Evolutionary Biology & Behavior Research Lab. He notes: "Stoneflies have a pretty interesting place in the field of insect flight research. Immature stoneflies are aquatic, and adults hang around the water too. “Adults of some species are known to use their wings for skimming themselves across the water. Because the body of the insect is supported by water, surface-skimming can be achieved wit

Stoneflies are hatching! Check out the video to see two of the numerous adult Stoneflies found hatching on Pine Creek, Tioga County, PA! Stoneflies are aquatic insects found in most PA waters.
