A little more info, I have been struggling for awhile now to attempt to identify similar symptoms. We do of course have brown and green stink bug here, and apparently increasing signs of BMSB activity. (But not necessarily in orchard.) I have been told that bitter pit is typically more superficial and shallow under the skin. On Honeycrisp, greenish sunken spots have fairly deep brownish flesh discoloration below the spots. I have some pictures of that too:

(Dave R., there was some hail here earlier (like June/July), but that damage was pretty easily identified earlier and that does not appear to be the cause of this.) I would presume that with some sort of microscope the best way to confirm stink bug or not would be to look for a puncture hole? Yes, no? I will slice some fruit later and send picts of that to the list. Thanks all for your feedback. Jon On Tue, Oct 8, 2013 at 10:53 AM, David A.
