Lathyrus latifolius, linifolius, niger, pratensis, sylvestris, tuberosus, vernus; Pisum sativum; Vicia cassubica, cracca, dumetorum, faba, pisiformis, sativa & subsp. nigra, sepium, sylvatica, tenuifolia.

larvae and pupae

detailed description in Skuhrovec, Gosik & Caldara.

notes

only in the lowest of the three pods in the pictures above a Tychius was found. This seems to indicate that the weevil larva does not play an important role in the galling of the pods.
