Habit and habitat

The adult fly grows to a length of 7 to 12 mm. Males are considerably smaller than females. However, they are delicate and short lived.[2]

Host

The species has a wide host range that includes all large-stemmed grasses except oats, Avena sativa L. (Macedo et al. 2005a).[2][3]

Distribution

It is known as a chronic pest in Northern Great Plains of the United States and also an important pest of wheat in the Canadian Prairies.[4] The species is distributed widely in various regions of the USA and Canada.[3]
