What are these bugs on my beautiful birch?
What are these bugs and how do I get rid of them? My birch has been super healthy this year then all of a sudden in the last week it’s been attacked by these things which are everywhere. How do I get rid of them?
It looks like some sort of leaf miner damage.
Unlikely to harm your tree despite the state of the leaves.
