Looks like something is eating your leaves
whatever it is (and it could be a couple dozen things) it is probably well camoflauged. I’d put money on a caterpillar or canker worm.

Check at night if you want to catch it.
Most caterpillars hide during the day and don't hide at night, so it'll be easy picking if you have a flashlight.

The uneven shapes indicate caterpillar or maybe slugs or snails.
If you have not seen the culprit that probably means it is feeding at night. Take a torch out and check the trees after dark to try to ID the culprit.
Check under the leaves as well as on top.

Thanks that makes sense as I cant find it but knew something has to be eating them. Will try to look after dark.

Caterpillars for certain. Most are in their Hey Day currently. All of my hornbeams and some of my maples and oaks look like this now. Gypsy Moth is prevalent at my house again this year and their caterpillar stage is making a big mess.

Anything to do about it or it is what it is? Trees seem healthy other than some leafs chewed

You can spray but that’s like using a shotgun to kill a fly. The damage on your tree is not very extensive which indicates to me that it’s only one or two bugs. I get canker worms (inchworms) by the ton and tent caterpillars that work in teams that can completely defoliate a medium size bonsai maple in an afternoon
I get rid of the canker worms by tracking them down visually and squishing them. They are well cammoed up green to look like leaves or brown to look like twigs. Caterpillars and canker worms typically hangs where you see damage staying very still. They’re easy to miss but look closely and don’t ignore “odd” things that might be subtle

Dust it!
BONIDE® Captain Jack's Deadbug Brew™ Dust
Back in 1892, on the grounds of an abandoned rum distillery on a Caribbean island, a soil sample was collected. In this soil they found a unique bacterium with insecticidal qualities that Spinosad would later be extracted from. Captain Jack's Deadbug Brew Dust uses Spinosad's insecticidal...

Check under all the leaves for caterpillars, easy enough to manually remove. Bag worms completely defoliated my favorite hornbeam i collected this spring in a day.

Yeah have looked multiple times not seeing anything which is why I reached out asking here. Will check after dark as others have mentioned to see. Thankfully limited to couple trees and still look fairly healthy but would like to get rid of the problem if I can find it

Lots of different names for those caterpillars. Looper, Inch worm, and other local names. Not surprised you had trouble spotting that one because they stand still and pretend to be a stem of a plant.
A good insecticide for caterpillars is 'Dipel' or any other brand that contains Bacillis thurigensis. It's a natural fungus that only affects caterpillars that eat it but won't affect birds or spiders that eat the caterpillars or any larger life forms.
Spray it on leaves then any caterpillars that take a bite of the leaf will turn black and die in a couple of days.

Canker worms are annoying and they're everywhere if you live near a forest or woodlot.

They use to be aphids, those are dead. Aphidius wasps lay their eggs on aphids, then the aphidius wasp larvae feed on them and then leave "aphids mummies", or empty exoskeletons, the hole being the exit point for the wasp when it matures.

Interesting so this would have had to been this year sometime I assume since under leaves. I did Notice none moved and went through tree trying to remove them. Thanks for letting me know what they were/are
