Biology
Status: Very local and patchy in England and Wales only. Scarce (Notable B)
Habitat: Calcareous grassland, woodland clearings, heathland, roadside verges, sand pits and sand dunes.
Host plant: Various mulleins, Verbascum spp.
Overwintering: As adults, probably also as larvae, and possibly also as eggs (i.e. probably two generations per year).
Food: Adults on leaves, larvae at roots.
Other notes: Adults may be parasitised by an unidentified nematode. Similar to L. nigrofasciatus, but elytral punctures coarser and denser than on pronotum.
