Ochsenheimeria urella is a moth of the family Ypsolophidae. It is found in large parts of Europe, except the Iberian Peninsula, most of the Balkan Peninsula, Ukraine and Lithuania.[1]
The wingspan is 9–12 mm.[2] Antennae in male hardly, in femalerather strongly thickened with rough scales to above middle. Forewings narrower than in Ochsenheimeria taurella, in male rather dark fuscous, in female greyish-ochreous more or less mixed with fuscous. Hindwings are brassy-purplish-fuscous, thinly scaled towards base.[3]
Adults are on wing in July and August.[4]
The larvae feed on Agropyron, Bromus, Hordeum vulgare, Melica, Secale cereale and Triticum aestivum. They possibly mine the leaves of their host plant for a few days. Later, they bore in the stems.[5] Larvae can be found from April to May.
