This is a synthesis of historic specimen data, published information, and the results of observation and experimentation in the field and greenhouse. The primary food plant of Nearctic L. subrufus is Onosmodium molle (Boraginaceae) and the known distribution of the beetle includes most of the plant’s wide midcontinental range. Adults feed on all above ground tissues except seeds; larvae feed on roots. The species is univoltine, spending winter as larvae. Daily activity patterns of adults are presented and three predators reported (Sinea, Nabicula, Enallagma).
