Catapion seniculus (Kirby, 1808)
the larvae develop within the stems, and also pupate there. Probably only little galling takes place.
Fabaceae, narrowly monophagous
Trifolium fragiferum, hybridum, medium, pratense, repens, resupinatum, trichopterum.
Most often recorded on T. pratense (Dieckman, 1989a).
Buhr writes that the species would cause galls in Medicago, Vicia, and Trifolium; this is seriously doubted by Dieckmann. However, Delbol presents an even longer list (Medicago, Melilotus, Ononis, Trifolium, vicia).
