Frit Fly
A tiny fly that is a major pest of oat crops and ryegrass. Larvae bore into plant stems causing 'dead heart'. Named from the Swedish word for grain. Multiple generations per year.
Did You Know?
Despite being only 1.5mm long, it can destroy entire crops of oats by killing the growing shoot inside each stem.

Its inability to fly has led to high genetic divergence between neighboring mountain ranges.
