Adult females are red to orange red in colour. The wings are covered with small hairs and have a fringe at the margin. The elongate egg is orange yellow. The female lays the eggs near the spikelet tip while the spikelet is in bloom. The full grown maggot is orange red to red colour and dark mouthparts.
The larvae feed on developing grains. The maggots feed on the developing grain and arrest its growth. This causes the seeds to shrivel and become malformed. In heavy attacks the whole head may be empty of normal grains.
