Possibly, we have the climbing type cutworm here that eats leaves and not just young seedlings. But it could also be mice, slugs, snails, weevils. Best way to find out and target the correct pest is to go out at night with a flashlight and look.

Slugs or snails sometimes nibble on young leaves, but the only times I have lost entire leaf blades as you describe, it was from deer. They sometimes eat the very young leaves, but as the leaves age, I generally find the bitten off sections nearby where the deer spit them out.

Thank you for the responses.
I'll try the 'at night with a flashlight' to see if I see anything.
I doubt that it's deer, as we are pretty much 'in the city' and have only seen deer near here once in the 8 years we have lived here. lol But boy wouldn't that be a hoot to see a deer in the flashlight!
What about squirrels? Have loads of them and I caught one chewing the bark off the hugh maple tree...

A rabbit did that to several of mine. They sent up new leaves but I'm still trying to trap the varmint. My pooch gave him a run for his money and he may have decided this is not a safe neighborhood - I hope!
