NHMO.</p><p><b>Biology and notes:</b> The orange-yellow larvae live freely among the florets in the capitula of <i>Centaurea scabiosa</i> and <i>C. nigra</i> (Asteraceae). Infected flowers become somewhat stunted. Probably univoltine. Pupation and hibernation in the soil. Our material does not fit this description perfectly, as it was collected from <i>Centaurea jacea</i>, and our larvae were pink rather than orange-yellow. However, DNA barcoding of one larva collected at Finnerud in 2019 gave 100% blast match with <i>Dasineura miki</i> collected from <i>Centaurea nigra</i> in the UK (Dorchin <i>et al</i>. 2019, supplementary material), and larvae from Denmark identified as <i>Dasineura miki</i> are also pink. We interpret our material as belonging to <i>Dasineura miki</i> and propose <i>Centaurea jacea</i> as a new host plant for this species.</p><p><b>Distribution:</b> Only known from UK, Austria, Norway and Denmark.</p>
