Status
Morley’s Final Catalogue: Bred Holbrook, Bentley and Wetheringset in 1931-3 (Whit).
Recent Status: A common species across Suffolk.
Life Style: A double brooded species that can be found during April and May and from July to October. The larvae feed on Corylus leaves. They pupate in a cocoon in the larval habitation. The pupal stage passes the winter.
Identification: There are three species of Phyllonorycter with two complete fascia and no basal streak. P. froelichiella is the largest at 9 to 10mmm wingspan. P. klemannella is 8mm and P. nicellii 7 to 8mm. P. nicellii has the pair of marks beyond the two fascia relatively long and often touching. In P. klemannella they are distant and appear along with the next pair to be placed alternately. P. klemannella has a silver grey thorax, it is orange brown in the other two species. All three species have a black scale suffusion in the wing tip rather than a sharply defined spot.
The larvae of P. nicellii construct a blister blotch on the underside of a leaf between veins. At maturity this is 15 to 20mm long. The larvae leave a green patch of parenchyma in the central area of the upper surface of the mine which distinguishes it from the otherwise similar but smaller Parornix devoniella mine. https://mothdissection.co.uk/species.php?Tx=Phyllonorycter_nicellii  | Determination by Genitalia Examination Required | |
