Tetanops myopaeformis
The sugar beet root maggot ("Tetanops myopaeformis") is a species of picture-winged fly in the genus "Tetanops" of the family Ulidiidae. It is a serious pest of sugarbeets in North America. The fly was described first by the name "Eurycephala myopaeformis" by Viktor von Röder in 1881. In 1907 the name was emended by Friedrich Hendel to "Eurycephalomyia" in order to avoid confusion with the preoccupied name "Eurycephala" for a genus of leaf bugs, now called "Halticus".
