General comments:
Most species of Parnornix can be named reliably from their larval mines but in cases of difficulty the adults should be reared through for examination. However, almost wild-caught adults will be worn, to at least some degree, and in most cases we will insist on genitalia examination to obtain the correct species name.

Widespread but rather local and never especially numerous. There has been confusion in the past between this species and Parornix carpinella, but it is now clear that the Parornix on Hornbeam is carpinella whilst that on Beech leaves is fagivora. For further discussion see Emmet (1986). Records dating to before 1986 are treated as unconfirmed and are not mapped. The distribution map has been compiled from records relating only to mines and/or folds on beech trees (or adults). Separation of adult fagivora from adult carpinella requires dissection of the genitalia.
