A study carried out by Pouvreau et al. (1995) showed that the pollen spectrum of females in the département of Essone (France) is largely dominated by Asteraceae pollen of the group Cichorioidea, visiting plants in the genera: Centaurea, Cichorium, Cirsium and Picris.
Pekkarinen (1998) lists plants in the following genera of Asteraceae as pollen sources in Finland: Centaurea, Hieracium and Leontodon.
