Fun facts
The dark bands on its wings look like the legs of a jumping spider. That trick scares off hungry animals.
Long ago these flies only lived on hawthorn berries. About 150 years ago some of them switched to apples.
The maggot is pale and hard to see, but if it eats green apple flesh, the green shows through its skin.
It spends the winter as a pupa in the soil and comes out as a fly in summer, mostly in August.
The female has four white bands across her shiny black tail end.
