Birch Tree Change

Asked October 4, 2018, 2:50 PM EDT

I noticed this fall that the birch tree leaves turned brown instead of their usual yellow. Is there a pest or disease attacking these birch trees?

We have had a terrible infestation late birch leaf miners. They are a larva the eats the inside of the leaf.

Will this infestation kill the birch trees?

The trees will recover fine next spring. Fortunately, the infestation occurs late in the year and the trees have had the opportunity to store up lots of sugars. I expect this to occur again next year.
