Hello - I have a two year old birch tree. It's been doing great. Just noticed today many leaves are turning brown, crinkling up dried and when I look up I can see lots of little pinpricks in the leaves letting light through. Is this birch leafminer or bronze birch borer?/

Not having a picture to refer to, or type of birch tree, what you are describing sounds like spiny witch hazel gall on river birch trees . Another possibility is fall cankerworm caterpillar. Please refer to the following website https://bygl.osu.edu/node/719
