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.
Common Moth Fly
A tiny grayish moth fly with broad, hairy wings giving it a distinctly moth-like appearance. Its wings are held flat over the body at rest, and it runs in short hops when disturbed.
Did You Know?
Moth flies are important components of sewage treatment trickling filter beds where their larvae help break down waste.
