Thanks @rossn
I didn’t find an insect ID thread, but did post in a more heavily peach oriented thread. I’m a mix of curious and concerned, as I have had trouble getting peach crops here (west of Loveland, 5000’) due to late frosts, and this is a late blooming Flamin’ Fury variety that I had high hopes for. It was off to a pretty good start and hope this doesn’t slow it down.
Appreciate the offer of materials, but think I’m set. I’m learning a lot from this GF community, even though I’ve been gardening in Colorado since the 80’s 
To be more accurate, late frosts and/or bud killing winter cold snaps.
No worries. Interested to hear how Flamin’ Fury does for you. Here is the Insect and Disease Identification Thread

Is that cherry? Or? Some trees have a hollow center or “dissolving” center. Waaaaay too small for carpenter bee. I’d probably wax or sealant spray that though.
Edit: hahaha 
you did say peach.
Peach. Agreed!
Is this brown rot? I’ve noticed this on a few of my Geo Pride pluots. There isn’t anything on the Splash or Emerald Drop pluots on the same tree.
To me looks more like feeding spots from plum curculio or brown marmorated stink bug. Possibly cherry curculio, but as in the name I think they pretty much focus on cherries.
If you have a lot of these on your tree you could take one and do exploratory surgery on it to see if these are egg deposit sites with offspring enjoying the seed. Very important to travel the pathway from the spot to the pit. That’s what I would do. If it is on many of them, you need to start using Surround just after petal drop in the future.
We went to Dever botanical gardens about a month ago and they have a huge apricot tree that was loaded with fruit. Every one of the marble sized fruits was covered with feeding marks, likely from some sort of curculio.
Thanks, I’ll check a couple of them to see if I find anything. I do have some Surround from a couple years ago so I’ll make sure to use that next year.
Looking like a good window for summer pruning is coming up. Just after solstice, dry (reduced fireblight risk) and following some hot spells (reduced cytospora risk).
I’ve always heard to get tape off grafts by July 4, and I did that last week. Probably a little late since there was beginning to be some girdling. Several grafts have really popped after being “set free” of electricians tape. Of course we got 3 days of rain right after that, so I am watching for any FB strikes.
Fingers x’d, it’s been a good season here so far.
Typically I’d aim for the hottest weather to do any summer pruning on apples and pears. FB can only survive at intermediate temps (I’d have to look them up, but think up into the mid-upper 80’s).

Thank you!
Further research gave me this from WSU site: “Cell division is minimal below 50° F, and relatively slow at air temperatures between 50 to 70° F. At air temperatures above 70° F, the rate of cell division increases rapidly and is fastest at 80° F. Above 95° F cell density on and in the plant can actually decline (Pusey and Curry 2004).”
Humidity >60% and nighttime temps above 60 degrees also increase risk.
So I guess I’ll prune peaches and cherries and wait for it to get hot again.
I think the second half of July through first half of August is usually the window here for summer pruning and avoiding fireblight.

Anyone else seeing E pears come 3-4 weeks early this year?
I have a Bartlett that the earwigs started getting to, and when tilt-checked, some appear to be ready for picking.

I now have Jupiter and Somerset grapes on the vine. If anyone wants to try them, message me.

Hey Jerry, if I make it your way while some are still on the vine, I’d love to. How long until you, the squirrels, or raccoons get em?
At least a week, probably longer
A little late to reply, but my pears are on normal schedule. Off year though, very light set.
Paul, I would recommend keiffer for your heritage pear trees that can shrug off FB.

Anybody have luck with sweet cherries on the front range? I have a pear tree that bit the dust and am looking to replace it with something else.
