Morley’s Final Catalogue: In numbers at Sproughton and Bromeswell, bred in 1932 (Whit).
Recent Status: A common species that is widely recorded in Suffolk.
Life Style: A double brooded species that can be found from April to August. The larvae feed on Alnus species. They pupate in a white 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. klemannella create small blister blotches on the underside of the leaves. There may be several on a leaf. They tend to be more rounded than other Alnus feeding Phyllonorycter. More Info
