Species Account


Many records are of larva.

Similar species: Adults similar to other Parornix spp; leaf-mines similar to 0308 Deltaornix finitimella, but larva distinct.

Sutton & Beaumont, 1989: Records are quite widespread and from all five vice-counties but some may be due to confusion with P. finitimella (Zeller). Distribution map 132 in MBGBI 2 also shows records from all five vice-counties but no confirmed record is available from VC65.
