Species Account


Most records are of leaf-mines.

Sutton & Beaumont, 1989: Recorded from all five vice-counties. Locally common among St John's-wort.

2013 (CHF):Locally common is still a good description of this species which mines various species of Hypericum, both wild and garden varieties. It is unlikely to be mistaken for any other species. The mine starts as a long narrow gallery with linear frass, traversing the leaf several times before abruptly turning into a large irregular blotch with scattered frass which tends to be concentrated in the centre.
