Phyllocolpa carinifrons ( BENSON , 1940)


Phyllocolpa carinifrons ( BENSON, 1940)  

Leaf-folds were abundant on Salix pentandra   . Identification based on the generally accepted monophagy of P. carinifrons   on Salix pentandra   and observations that no other Phyllocolpa species   uses this willow as a host ( Kopelke 2003; as P. excavata (Marlatt))   .

This species has already been recorded from the Red Moss at Balerno ( Liston 1981a).

Phyllocolpa erythropyga (FÖRSTER, 1854)  

Specimens key to Pontania leucosticta (Hartig, 1837)   in Benson (1958). Kopelke (2007a) mentions the more extensively pale pronotum of P. leucosticta   as one of the characters that distin- guishes it from P. erythropyga   . Colouration of the pronotum varies widely in the above specimens. In most only the edges of the pronotum are pale. Those from Braemar are the darkest. One of the Balerno specimens has an extensively pale pronotum. The distribution of ctenidial teeth at the base of the lamnium in all these females is very similar and indicates that they all belong to P. erythropyga ( Kopelke 2007a)   . Dr Kopelke examined a female from Claybokie and also determined it (Kopelke, pers. comm.) as P. erythropyga   . He remarked that the cerci seem unusually long, but that this character possibly varies. P. erythropyga   is monophagous on Salix aurita   and P. leucosticta   on S. caprea   according to Kopelke (2007a).
