Cephus cinctus, also known as wheat stem sawfly,[1] is a slow flying, yellow and black coloured, destructive pest found mainly in western North America.[2][3]
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]
The species has a wide host range that includes all large-stemmed grasses except oats, Avena sativa L. (Macedo et al. 2005a).[2][3]
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 US and Canada.[3]
