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. harrisella create a short (14 mm at maturity) blister blotch variously placed on the underside of a leaf that shows just one large crease. More Info
