Species Account

Sutton & Beaumont, 1989: Recorded sparsely from all five vice-counties.

2013 (CHF):Virtually all of our records are from leaf mines on hawthorn. If the mine starts away from the leaf edge, it begins as an erratic gallery zigzagging to and fro in a small area near the egg before moving to the edge of the leaf. If (as is more common) it starts at the leaf edge, this stage is missed. The mine follows the leaf margin for a long distance and then leads to a blotch with scattered frass. Along with all hawthorn mines, care should be taken in identifying this species as not all mines are typical.
