Mainly known from some very old records in LI and OV, and discovered again in 2020 in NA after a long period with no observations.
Greyish green with darker dorsal and dorso-lateral lines; head and prothoracic plate dark brown to blackish; pinacula black.
One generation a year: September, hibernating till May.
Mainly on Centaurea scabiosa, but the larva has also been observed occasionally on Centaurea nigra and Serratula tinctoria.
