I was looking at one of my Hibiscus this afternoon and noticed what you see in the photo below. As far as I can see there are 3 or 4 bud like this.

Hello Chris,

Just a guess, Japanese beetles? I have had a whole hardy hibiscus destroyed by them. They also love to munch on my knock out roses, and crape myrtles.

Hope you figure it out, good luck! 😊

Thanks Angela, right now it's hard to tell as the local 'tame' deer are feasting on all my Hibiscus . They love the buds as you can see exactly where one was and where it was nipped off at.
