The clubbed portion, however, is quite variable within species, being quite distinct or only slightly developed (Parsons 1943). These varieties are more resistant to corn earworms and the beetle itself and therefore are less likely to be infested by sap beetles. Twenty one genera have so far been reported Adult (left) and larva (right) of the large sap beetle (picnic beetle, nitidulid), Lobiopa insularis (Cast.) Coleopteran, (order Coleoptera), any member of the insect order Coleoptera, consisting of the beetles and weevils.
