Galeruca rufa
Introduction '''''Galeruca rufa''''' is a species of leaf beetle native to Europe.It has been observed defoliating ''Convolvulus arvensis'' L. (field bindweed). ''G. rufa'' appears to feed only on the genera ''Convolvulus'' and ''Calystegia''.Studies were halted on this species when it was determined to reproduce successfully on several North American sweet potato varieties.
