DESCRIPTION: An 'Artichoke Gall' that comprises of 60 - 80 terminal leaves that become clustered to form a single gall whose outer leaves are dark green and the inner ones almost white. Each gall contains a single orange-red larva that feeds within the gall after a resting period and then pupates inside and emerges as an adult about 1 month later. The galls eventually turn brown and can stay on the plant right through to the next year. DISTRIBUTION: Widespread throughout and one of the commoner galls. HABITAT: On the developing buds of Yew.
