 Along with the Lundy cabbage, Psylliodes luridipennis has been listed in the United Kingdom Biodiversity Action Plan, and an action plan for its conservation, along with the conservation of other endemic species, has been prepared. This plan revolves mostly around the control of Rhododendron ponticum, an alien species which threatens the Lundy cabbage. The beetle is threatened by fluctuating numbers of Lundy cabbages. Though it is quicker than P. napi to recolonise new growth after bad years for the cabbage, it is slower to recover than the cabbage itself.
