Hi Heidrun,

I wrote yesterday in another topic that the photos of cases conserning C. therinella are incorrect and belong to C. peribenanderi, as also you have noticed.

I have bred several times both C. therinella and C. peribenanderi, and there is no doubt about this: C. therinella lives on Fallopia and Polygonum, C. peribenanderi on Cirsium and occasionally also on Centaurea.

Best wishes,
Jukka
