This year that little worm may be the larvae for the Spotted Wing Drosophila (SWD) (aka Cherry Vinegar fly). The fly is new to the area and attacks cherries, raspberries, blackberries, blueberries, strawberries, plums, grapes and nectarines. Breeding sites are overripe or fallen fruit. Fruits become infected near harvest time (thats blueberries and raspberries now).
