NIWA scientists have discovered two species of caddisfly that are new to science, using specially-designed ultraviolet light traps. One species was found in a southern Waikato river, and the other, a microcaddisfly, and literally the size of a pinhead, was found in the Mangaiti Reserve in Hamilton City.
