UK Status

Widespread but infrequent in Britain.

VC55 Status

Rare in Leicestershire and Rutland. There were only 3 VC55 records for this species up to March 2015 - two identified from galls.

Further Information

The revised British Plant Galls Keys indicates that these galls are not well known and identification using the keys should be verified by rearing and identifying the adults.This is rarely done, so although we have found no other likely causer for the galls illustrated, we wish to point out that they have not been proven by rearing through to the adult stage.
