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.
