An oak apple is a mutation of an oak leaf caused by chemicals injected by the larvae of certain kinds of gall wasp. They are so called because the gall, which can measure up to 5 cm in diameter but is normally only around 2 cm, looks a little like an apple.

European oak apples are caused by the Biorhiza pallida gall wasp and American oak apples by Amphibolips confluenta. ^[1]

Oak apples may be brownish or reddish.
