Sour and sul^acid varieties, such as theMorello and Montmorency, are worst injured, but black cherriesand indeed all varieties are more or less damaged. The fly is slightly smaller than that of the apple-maggot, beingabout one-sixth inch long with a wing expanse of three-eighthsinch. The body is blackish, the head and legs are pale yellowish-brown, the sides of the thorax are marked with a longitudinal.

The maggot is about one-quarter inchlong and is indistinguishable from the apple-maggot. Life History.—The eggs are deposited just under the skinof the cherry from June until .\ugust. or probably during thewhole season of the fruit. The eggs hatch in a few days and thelittle maggots penetrate to the pits, feeding on the flesh andforming a rotting cavity very similar to that made by the grub ofthe curctdio.
