Species Account

Sutton & Beaumont, 1989: Local and rare, no recent record.

2013 (CHF): Very local in the county with few recent records. The adults are much plainer-looking than others of this genus as the name fuscatella suggests. The larvae form almost spherical galls in birch branches of 3-13 mm diameter, usually at a node. Often several adjacent nodes are affected. The larva hibernates in the mine. The presence of the larva within the gall is suggested by reddish-brown frass around the exit hole.
