I really would like to avoid finding out. One case described a barley field where cutworms were feeding extensively on the volunteer sunflowers that were emerging. Flea beetles have also been reported in sugarbeets. In isolated cases, treatments have been made where the injury appeared to be threatening the plant stand. In fact, in one field beetles outnumbered grasshoppers.
Blister beetles feed on alfalfa, potatoes, beans, and lupins.
One report was that they had fed extensively on a beet field. They may also be attracted to other crops and ornamentals. In addition, they feed on grasshopper eggs in the larval stage. In the southeast, some small grain fields and beet fields in particular are being watched closely. Inspections of these areas have found populations ranging from less than 10 per square yard to more than 50 per square yard.
