Morley’s Final Catalogue: Occurred at Hemley and Euston 1932, bred at former (Whit).
Recent Status: Rarely recorded in Suffolk and probably under-recorded owing to identification constraints at the larval stage.
Life Style: The species is double brooded and can be found during April, May, July and August. The larvae feed on a variety of Salix species. They pupate in a loose cocoon in the larval habitation. The pupal stage passes the winter.
Identification: The moth can be identified on superficial characters. Identification by genitalia dissection is possible but difficult. The ground colour is a variable light golden or sienna brown. There is a variable basal streak. There are four costal and three dorsal marks. The first pair often joined forming an obtusely angled fascia with the dark edging interrupted. The second pair are separated by a suffusion of black scales centrally in the wing at this point. The three final quite narrow marks can sometimes join. There is a black terminal spot sometimes white beyond and a dark cilia line. The only similar species is P. dubitella that has the first pair of marks/fascia forming an acute angle. The mine is a blister blotch on the underside of a leaf in various locations. It cannot be separated from other Salix feeding species. The pupal exuviae can be separated on any specimen found on a Salix species other than S. viminalis. Refer to MBGBI Vol 2 for this purpose. More Info
Retained Specimen / Photograph will be Required.
Mine: Moth needs to be reared and, in some cases, possibly dissected.
