Yorkshire Status: Very common and widespread resident.
This species is common and widespread across all of the county and is present almost everywhere that hazel grows. The adults cannot be separated from other Parornix species without dissection, so most of our records are of leaf mines. The initial mine is a brownish square or rectangular blotch on the under side of the leaf. We have seen this mistaken for the longer and less brown mine of Phyllonorycter nicellii at times. It then makes two or three successive folds at the margin of the leaf, and these can be upwards or downwards.
