Maple Leaf Spot Gall

Cecidomyia ocellaris


Red circle surrounded by white ring surrounded by red ring. Larvae develop in leaves of maples, usually Acer rubrum and usually in the spring. After a week in the leaf (during which time the gall is formed) the larva drops to the ground, burrows, and pupates. Adults emerge the following spring.
