The mine formed by this species is found on the upper surface of various plants including Campion. It starts as a white linear blotch mine but after a while the mine may extend to form a larger white blotch which contains very little frass except a few black specks anchored to the floor of the mine. The feeding punctures are on the surface.
On various plants including Campions.
Mines from June to October.
Pupation takes place outside of the mine.
Widespread but rather local, with most records from the southern half of Britain.
Local in Leicestershire and Rutland.
