Morley’s Final Catalogue: Not listed.

Recent Status: A rarely recorded species in Suffolk, possibly overlooked.

Life Style: The moth is double brooded and can be found in April, May, July and August. The larvae feed on Quercus species. They pupate in a white cocoon that occupies most of the blister blotch area. The pupal stage passes the winter.

Identification: There are four similar species of Phyllonorycter that are white basally and weakly marked. P. harrisella, P. roboris. P. heegeriella and P. tenerella. P. roboris has a bright ochre mark at the wing base. This species is not recorded in Suffolk but is recorded in the Waveney valley in Norfolk. P. heegeriella has a narrow dark long basal streak. P. harrisella has three costal marks and P. tenerella has four. P. tenerella is particularly variable and can have the ground colour dark suffused and be more strongly marked.
The larvae of P. heegeriella create a small blister blotch that is generally less than 10mm long. It is variably placed on the leaf but commonly on the edge and in such a position causes the edge to fold over completely. More Info
