Three species of phytophagous insects were reared from the heads of Arctium minus (Hill.) Bernh: Tephritis bardanae Schrank., Orellia tussilaginis f. (Tephritidae) and Metzneria lappella (L.) (Gelechiidae). They were found to be parasited by two species of Hymenoptera: Bracon minutator (F.) and Habrocytus musaeus (Walk.) Inside the heads of A. minus was found a predator Orius minutus (L.), which probably had developed there.
