Insect-galls of the vicinity of New York City

Amphibolips confluentus

Large, globular, more or less smooth outside and filled with a spongy substance in the center of which is a hard woody kernel containing the larval cell. From 1 to 2 in in diameter. When fresh, it is pale green, soft and succulent, with the contents whitish. Later in the season the shell becomes brown, hard and brittle, with the kernel woody and the spongy substance dark brown, but remaining soft. Confined to the leaves of the trees belonging to the red oak group. Common.
