Temperate areas of the United States and Europe.
B-rated pests in California.
In California, this species can cause yield losses of 50-75% in barley grown under continuous cropping in the Tulelake innermountain region.
Feeding site establishment and development typical of genus.
Grasses, cereals, and weeds.

Egg hatch in water is very limited unless eggs have been chilled by storage below 5C for 1 to 7 weeks (Franklin et al, 1971).
Galls are generally cylindrical, spindle-shaped, or hooked.
Feeding causes necrosis, hyperplasia, and hypertrophy of cortex; also causes disorganization of xylem elements.
Crop rotation can be effective in California (1 year fallow or 2 seasons of potatoes increased barley yield - Allen, 1970).
