There is a Spring and a Summer Fishfly. The Spring Fishfly has a dark dorsal stripe, unlike the the light dorsal stripe on this Summer Fishfly. They are fierce predators and also feed on aquatic plants. They breathe through a pair of snorkel-like "tails" as shown in this video. They are very shy and well camouflaged, moving more slowly than a snail. Larvae live for 2-3 years and then leave the water to form a cocoon in soft mud under bark or a moist log. They only live as an adult for up to seven days, long enough to mate and lay eggs near water. The larvae of Alderflies, Dobsonflies and Fishflies are all commonly called Hellgrammites. Some clips are sped up 2-5 times. One clip is in real time and then repeated in slow motion. Filmed March 18-19, 2017 in the Missouri Ozarks, USA, from a farm pond.
