Sugarbeet root maggot

Tetanops myopaeformis

Maggots feed on sugarbeet roots and develop through three larval stages. They reach full size early- to mid-July, after which they stop feeding and enter a state of diapause until the following spring. Usually a single generation develops annually. There is some evidence that a small portion of the population pupates during July and emerges as flies during August.
