DESCRIPTION: The noticeably hairy galls of this species are caused by a wasp. The gall itself is a rather robust globe that contains a single larvea. Each globe begins yellowish-green and becomes reddish with age. The white larvae pupate in the galls and new adults emerge in late spring. Fresh galls have a minty smell and were apparently eaten by French peasants. DISTRIBUTION: Widespread in England but not overly common. HABITAT: On the leaves, petioles and stems of Ground Ivy.
