Some neglected tropical diseases share common vectors (sandflies, black flies, and mosquitos). Biting midges (Ceratopogonidae) are sometimes called sandflies or no-see-ums (no-see-em, noseeum). Four weeks later, Bradtke experienced similar symptoms, due to the mosquitoes and sandflies. They feed on beetles, diptera, hemiptera, insects, sandflies and have been observed eating hairy caterpillars. There are six species of native sandflies (blackfly, Simuliidae) with one endemic to Fiordland. The sandflies inject the infective stage, metacyclic promastigotes, during blood meals. The bacterium is transmitted by sandflies of the genus "Lutzomyia". Emergence traps have been used to monitor important disease-vectors such as Phlebotomine sandflies. It is a vector-borne disease that is caused by the bite of sandflies. It is spread by the bite of certain types of sandflies. New Zealand sandflies are in the genus "Austrosimulium", a type of black fly. The district was originally known as Toka-a-Namu, which refers to the abundance of sandflies. The maraba virus, first identified in Brazilian sandflies, is being tested clinically. The life cycle of "Leishmania" is completed in two hosts, humans and sandflies.
