Document Summary
Synapomorphy: hind wings modified into knob-like structures called halteres. Sends info about flight position (helps in flight) Basal flies: aquatic larvae = biological indicators of water quality. Family culicidae mos(cid:395)uitoes require blood for development of their eggs. Adult females w long needle-like mouthparts with central sucking tube. Mosquito borne diseases: wnv, malaria (anti-coagulant saliva causes us to itch) some pollinators: eggs laid in standing freshwater larvae aquatic but air-breathing: important food source for aquatic animals, specialized structure at tip of abdomen for gas exchange. Family simuliidae bla(cid:272)k flies females need blood for egg development. Eggs laid in fast moving water (eg. streams) larvae attach to rocks. Family ceratopogonidae no-see-ums, biting midges, punkies females need blood feed on nectar and are pollinators of theobroma cacao (used to make chocolate) Family tabanidae ho(cid:396)se flies, dee(cid:396) flies females have painful bite; saw/slice flesh. Many larvae predaceous can be in flight but completely still.
