Rhopobota stagnana (Denis & Schiffermüller, 1775)
The larvae of the first generation live in the flowers heads, feeding on the developing fruits; they may also bore into the peduncle. The larvae of the second generation start by making a full depth, transparent, irregular gallery or blotch. Frass sometime missing altogether, but sometimes in local concentrations, mostly near the start of the mine. The older larva leaves the mine and then lives between two spun leaves or in a silken tube below a leaf.
