Haplodiplosis marginata (von Roser) - (saddle gall midge)
This gall midge is a pest of cereals in Europe. The larvae attack the stem tissue near the nodes causing characteristic swellings and deformations (saddle-shaped galls) under the leaf sheaths. Infested cereals include wheat, barley, rye and less often oat. During outbreaks, there may be up to 60 galls per infested stem.
The adults only live for a few days and lay their eggs on the leaves. The hatching larvae move to the leaf sheaths and each larva induces a gall where it develops over a period of 1-2 months. There is only one generation per year. The fully grown larvae drop to the ground and stay in the soil until the next spring, when they move to the soil surface and pupate. The fully grown larvae are around 3 mm long and orange-red.
