Lixus bardanae (Fabricius, 1787)

on Rumex

parasite

Oviposition in the petiole of a low leaf or in the stem; the opening is closed with a wad of chewed plant material, that later turns dark red. The larvae bore tunnels, descending into the stem. Ultimately they also pupate here, in a frass-lined pupal chamber. One petiole or internode may harbour up to a dozen larvae.

Recorded also from Rheum, but this relation is not repeated by later authors.
Also the reference to Heracleum by Balalaikins & Bukejs needs confirmation.
