​Stoneflies are not actually flies but are in their own order of insects. They have long antennae and wings with many veins that lay flat across the back. They also have an elongated body. Stoneflies may have an orange color on the neck along with bulging eyes on the sides of the head. These insects are mostly found in and around healthy streams with a stony bottom. Winter stoneflies are small and a blackish, dark brown color.
