I had a small fly with speckled wings basically destroy my peaches this year, about the size of a small "housefly". They lay eggs through the skin that go to the pit and then if left hatch into small worm type larvae. They got into every peach, but did not start getting there until the peaches were starting to ripen. It at first looks like a small round spot, but with time rots the fruit and turns it brown. What are they and how do you get rid of them?



Based on the information provided it appears that you have the “Walnut Husk Fly”.  As the name implies, this is a common pest on our local Walnuts.  However, when grown in proximity to a peach tree, the fly will also infest the peach fruit.  Insecticides that offer control are Malathion, diazinon, or pyrethrin.  Also, here is a very informative link for you to learn more. http://jenny.tfrec.wsu.edu/opm/displaySpecies.php?pn=160  Please feel free to contact me if you have any further questions.
