Leaf Miner

Today we welcome our neighbor Leaf Miner to the blog. Good Morning Leaf Miner! Who exactly is Leaf Miner? Where can you find him?

We are so glad you asked. Leaf Miner can be found on Hawthorn trees. Adults emerge from the soil in early May and sting the leaf, laying eggs as they do. The eggs then hatch, and the caterpillars that you see here(look for the backwards "c"), eat between the layers of leaves! You can see the damage they do below. When they are finished, they cut through the leaves, pupate in the soil, and overwinter as moths in the soil. As you have already guessed, they remain there until May when they start the process over.

What can you do? You can treat with acephate now or in the fall with an imidacloprid soil drench.

We will be back soon with some more do it yourself tips!
