Finally got round to dissecting some specimens from the garden in 2020 (Great Kimble, Bucks). My garden contains Ox-eye Daisies, but no Tansies, so I was expecting this Dichrorampha to be the Orange-spot Daisy Moth D. alpinana. But the costal fold on the wing looked quite short, and following dissection it appears to be the Orange-spot Tansy Moth, D. flavidorsana. Apologies for the rather scruffy dissection and blurry photos but hopefully the smooth edge to the aedeagus can be seen.
This is a new species for me, and judging by the Atlas it may be new for Bucks? And I guess it is a cautionary tale that proximity of foodplant is no guarantee of presence of the associated moths.
