Remarks. These specimens belong to an aggregation of numerous “host races” or cryptic species associated with different host plants, at least two of which occur in mainland Europe. They are poorly distinguishable based on morphological characters that broadly overlap. One of them is associated with Centaurea jacea and Ce. trichocephala, and the other with Cirsium oleraceum and possibly more species of Cirsium and Carduus .
