Saddle gall midge is a sporadic pest, usually present at very low levels but occasionally reaching damaging levels in some years. Local epidemics have recently been reported in central England.

The worst damage is caused when larval feeding coincides with stem extension. Late-sown winter wheat and barley and spring-sown cereal crops are at the greatest risk. Winter-sown oats, while attracting adults for egg-laying, are rarely seriously damaged. Continuous cereals are more at risk, due to the larger numbers of overwintering larvae within the fields.
