Biology
Status: Widespread in England, rare in Wales, old records only in Ireland, no records in Scotland.
Habitat: Various
Host plant: Various Convolvulaceae
Overwintering: Only as larvae (adults die before winter)
Food: Adults on leaves, larvae in roots.
Other notes: Antennal segment 11 the same colour as segment 10 (in the similar L. succineus, segment 11 is slightly darker). L. pellucidus also has more strongly developed elytral 'shoulders', but dissection of the aedeagus may be required to separate these species.
