A major pest of cereal crops in Europe and other temperate regions. It feeds on ears and leaves, reducing grain quality and transmitting barley yellow dwarf virus.

Feeding on wheat ears during grain fill can reduce thousand-kernel weight by up to 20%.
Nose Bot Fly of Horses
A dark-bodied bot fly that deposits reddish-black eggs around the lips of horses. Larvae penetrate the lip mucosa and migrate to the stomach, then before pupation they reattach to the rectal mucosa, causing irritation and inflammation. The name refers to the reddish rectal inflammation it causes.
