Biology: The species is univoltine, adults overwinter under hiding object as aggregated. After feeding several days on leaves, they mated and laid their eggs (1-23) in flowerheads using rostrum by excavation of the oviposition hole. The larvae develop in capitulum eating and destroying the seeds. In late summer, larvae complete their growth; prepare pupal case in each flowerhead and pupation occurs in here. New generation adults emerge from flowerhead after waiting several days.
It feeds on Echinops sphaerocephalus mainly, also on Echinops orientalis.
