Centaurea cyanus
The larvae feed on "Arctium lappa", "Carduus crispus", "Carduus tenuiflorus", "Centaurea cyanus", "Centaurea jacea", "Centaurea scabiosa", "Cirsium acaule", "Cirsium arvense", "Cirsium creticum", "Cirsium vulgare" and "Onopordum acanthium". They initially mine the leaves of their host plant. The mine has the form of a short full depth corridor. The larva soon vacates the mine and continues window feeding from a spinning at the underside of a leaf. Larvae can be found from June to July. They are dull green with faint darker length lines and a black head. The species overwinters as an adult.
