That is strange looking. Doesn't look like recent feeding damage. The fruit will probably ripen properly and will taste like undamaged fruit. The only issue might be increased fruit cracking.

A lot of the pluots have a little crater in them and a few others have more of a path chewed out that looks like something burrowed/ate across the face of the fruit. I had been plucking off the ones that showed the damage but maybe I'll just leave the on and see what happens.

Probably some caterpillar ate on the fruit when it was small. Pull off what you can but leave a normal crop load. I think you'll be happy with the fruit.

Thanks Fruitnut. As always, your input is greatly appreciated.

That looks like a cluster that I would thin, and in so doing remove the most blemished pieces of fruit.
