Spotted Wing Drosophila

An invasive fruit fly from East Asia with a saw-like ovipositor that lets it lay eggs in ripening (not rotten) fruit — devastating soft fruit crops worldwide since its spread in 2008.

💡

Did You Know?

Unlike most fruit flies that only attack rotting fruit, this species cuts into perfectly ripe fruit with its serrated ovipositor — causing billions in crop damage globally.

Face Fly

A non-biting muscid fly that feeds on secretions around the eyes and nose of cattle. It is a mechanical vector of the cattle pinkeye pathogen Moraxella bovis.

💡

Did You Know?

It enters homes in large numbers each autumn to overwinter, hence the name autumnalis.
