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.
Sand-Case Caddisfly
A caddisfly whose larvae build smooth, curved cases entirely from fine sand grains cemented with silk. Adults are dark with hairy wings.
