Nationally scarce (Nb) in chalk downland, limestone grassland and woodland edges in southern England, northwards to Worcestershire. In Hampshire probably found across the central chalk downs, but also found to the north in woodland and urban areas, including around Basingstoke. Surprisingly rare in South Hampshire south of Winchester. Not recorded from the Isle of Wight to date. Wingspan 18-22 mm. Day-flying. The early stages may be sought during the winter months, but synthetic pheromone lures are used to attract males nowadays, and this has led to a marked increase in records of the species in recent years. Larva feeds in the stems and twigs of Wayfaring Tree and less often in Guelder Rose, over-wintering twice. Old galls are conspicuous, but tenanted ones are difficult to see.
