SUMMARY. In the laboratory, the larval food plants of Opomyza germinationis L. are, oate, wheat, barley, Lolium perenne, L. italicum, Dactylis glomerata, Festuca rubra, Poa trivialis and Cynosurus cristata . In the field, only a few larvae were found in the cereals, the chief host plants being the grasses. The injury is similar to that caused by the larva of Oscinella frith . There are three larval instars and pupation takes place inside the host plant near the ground. Adults emerge in mid‐June and live until early November. In the laboratory eggs were laid in September and October either on the plants generally near the ground level or on the soil near the seedlings. A description is given of the three larval instars, the egg and the puparium.
