none Enter Lixus punctiventris was collected and reared from larvae and pupae near Przedborz and in the Holycross Mts (Central Poland). Its development in stems of Crepis biennis L., but less frequently also in Picris hieracioides L. and Senecio jacobaea L., was confirmed, with field and laboratory observations on larval frequency and numbers in stems, timing of pupal stage, ability of the pupa to move actively along larval tunnels, and feeding preferences of young adults. The process of adult emergence from the pupa is showed on a series of combined photos. The 3rd instar larva and the pupa are illustrated. Total distribution of the weevil in Poland is mapped, and general pheno-logy is discussed. The parasitic Aritranis nigripes (Gravenhorst) of the family Ichneumonidae was noticed in the weevils' workings.
