Stoneflies are insects that like to be cold. They often live in fast flowing, mountain streams and are great indicators of water quality. Needless to say, they’re a little hard to find in southern Arizona! In fact, you have to go up in elevation quite a ways to find them during most parts of the year. This is the closest place where I consistently find them, Mt. Lemmon:
Sometimes it’s hard to believe you’re still in a desert up on top of the mountain! Trees that are more than 15 feet tall, water, bright vivid greens – it’s a whole different world!
