Eucosma cana (Haworth, 1811)
on Carduus, Cirsium
Eggs are deposited one by one at the outside of a still closed flower head. The larva works itself inside from the top, then feeds on the developing achenes. The late larve makes a frass filled tunnel in the receptacle, then leaves the head.
Occasionally Centaurea nigra.
The larva hibernates in the soil in a cocoon made out of silk and dirt, and pupates in the spring.
