As for the Latin that links cinnabar moth to ragwort, Tyria Jacobaeae to Senecio Jacobaeae, I have not yet discovered what the name signifies. I see the moth as scarlet, a friend sees it as crimson. Does Tyria suggest the ancient Tyrian dye which yields purple? And what of Jacobaeae? There's an evolutionary relationship between moth and ragwort, an exchange of toxins. Cinnabar caterpillars feed on ragwort, can strip it of leaves. apparently without killing the plant?
Images show several different cinnabar moths we found during the day, interspersed with eider duck, with linnet and reed bunting and a wealth of flowers. Now showing on this website's gallery.
