Acer buds damaged



This year I noticed the top of the tree seemed bare and didn’t the ususl
amount of buds as previous years. On closer inspection it looks like the buds may have been eaten or have died and dropped off the branch leaving a clean stump.
I’m wondering if perhaps some type of insect is eating the buds but wanted to ask if anyone has seen this type of damage before, I’ve attached some pics of the issue and appreciate any advice or guidance on how to treat or prevent this.
