What causes Flyspeck?

Flyspeck is a disease of maturing apples, caused by the fungus Zygophiala jamaicensis (also known as Schizothyrium pomi). ...

Apple maggot flies lay eggs in fruit and the fruit becomes pitted and misshapen. Each "sting” or hole created by the female fly as she lays an egg, forms a tiny spot or dimple. Pulp breaks down, discolors and starts to rot as a result of maggots (larvae) tunneling through the flesh.
