If you manage to get another look and can count the legs and make note if they have tails or not, that would also help. what is this?! In running waters there will be fewer species, but they should always be present. Any ideas? I’m afraid that I’m not certain what it could be, but if you could get a picture of it that would help greatly! The adults look quite similar to dragonflies as they also have a double set of membranous wings, but while a dragonfly’s back wings are larger than its front wings, the wings of a damselfly are all approximately the same size. One pair is for seeing below the water surface, while the other pair is looking above the water.

Daphnia can range in size (some may be hardly visible, while others can be close to a centimeter in size), and their color is dependent on their diet.
