A small (2 to 3 mm) reddish coloured weevil. The larvae mine the leaves of Sheeps Sorrel (Rumex acetosella) causing swellings along the mid rib or petiole. These are often reddish or sometimes yellow in colour. (see further information below).
Areas where Sheeps Sorrel is present.
Spring to Autumn.
Larvae mine the leaves of Sheeps Sorrel.
Widespread but infrequent in Britain.
Rare in Leicestershire and Rutland. There were only 3 VC55 records for this species up to March 2015 - two identified from galls.
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.
