Tychius crassirostris Kirsch, 1871
Melilotus albus (from Mik, 1885b); the gall to the left is already vacated.
The leaflets are folded over de midrib and contain one or more pea-sized, closed, unilocular galls. Initially the galls are almost massive and juicy, but when the contents have been eaten away they are hollow and leathery. The mature larva leaves the gall by making an opening in the wall. Pupation in the soil in a cocoon.
Melilotus albus, altissimus, dentatus, officinalis.
References to Medicago (Buhr, Dauphin & Aniotsbehere, Houard, Redfern & Shirley) need confirmation.
