Query re Plumed Prominent (Ptilophora plumigera) distribution

[Prichard,AW,NAR7 PRICHAA2 M]

Hi

Hopefully somebody can help me with this question.

The Plumed Prominent (Ptilophora plumigera) occurs in Suffolk (UK) but seems
restricted in the locations it is recorded from. We have searched (light
trapped) for it around the county in places where there appears to be plenty
of its foodplant but it seems to be restricted to those areas where the
foodplant is growing on a chalky soil. Has anybody else had this experience
of the moth being restricted to chalky areas?

Regards

Tony Prichard
