About Leafminers
Leafminers is a general term for tiny insects which feed and develop between the epidermal layers of leaves. Leafminers can be flies, wasps, moths or beetles. A common leaf miner is the birch leaf miner which attacks birch trees, but there are species which attack apple, oak, beech, elm, cherry, locust, and hawthorn. The damage is characterized by brownish, semi-translucent blotches on the leaves, representing the “mines” inside of which the immature larva are feeding. To differentiate leafminer damage from similar looking leaf spot diseases, look closely at the affected area of the leaf for the presence of the larva or its droppings inside the mined area.

I have black gum thees and cherry that are infested with tiny little worms living inside the leaves the they fall with little pieces of the leaves and stay in it for a while , how do I get rid of them ?
Hi Thia,
Have you had an arborist come out to take a look? Without being onsite, it’s difficult for me to diagnose your trees, but an arborist should know what the worms may be. Here’s a listing of our service providers– just enter your zip code on the right hand side to find the ones nearest to you.
Have a great day!
