Oak worms become moths, oak leafrollers turn into moths too, and gall wasps lay eggs that hatch into larvae inside the tree, creating galls.

These larvae grow inside the galls and become adult wasps. Oak bark beetles’ larvae become adult beetles, and oak root borers’ larvae become adult beetles that lay eggs to start the cycle again.

Why Are There Worms in My Oak Tree?

Are Oakworms Bad for Oak Trees?

Oakworms, despite their name, are not harmful to oak trees in the long run.

They might eat oak leaves, causing defoliation, but this will not cause significant harm to healthy, mature oak trees.

Oaks can grow new leaves, especially if the defoliation happens early in the growing season.

However, in some cases, like when oak trees are already stressed or are already experiencing other pest issues, oakworms can add to the problem.

In these cases, it might be a good idea to control oak worm numbers to avoid too much defoliation.
