Stoneflies (Order Plecoptera) are an important biotic component of aquatic ecosystems in northern Florida. The nymphs prefer cool, clean, running water and are excellent indicators of a healthy stream. Nymphs of this species, as well as other members of the family Perlidae, prey on a wide range of stream macroinvertebrates. Adults can be found around lights after dark. (Photo by Peter Kovarik)
