Many animals have the optimum range of their sight in the ultraviolet, for example, deer are far more sensitive in the ultraviolet than in our visible range, especially at night, and have absolutely no red cones, so they don't care about infrared.
Mosquitos are essential food for fish as eggs and larvae, along with black flies, no-see-ums, caddis flies and deerflies.
