In Europe a very common species developing in a variety of herbaceous plants (eg. Cardus, Urtica, Angelica, Chaerophyllum, Artemisia, Salvia, Aconitum). Like the other species of Agapanthia genus, the larvae of this beetle develop in the above-ground plant tissues (stalks). They cut off the plant stalk before pupation, create the pupal cells near ground level, and the adults leave the stalks via a newly created exit hole in the side of the remaining stalk.
