Sphenophorus adults – “rice levee bill bugs”.

Sphenophorus spp. - formerly called Rice Levee Bill Bug

Sphenophorus adults may occasionally attack rice in Louisiana.The numbers of Sphenophorus adults in rice fields are usually below level justifying insecticide treatment, but they may increase rapidly under favorable conditions and stand losses can occur. Bill bugs belong to the beetle family Curculionidae (weevils) and are a relative of the rice water weevil. Adults feed near the base of young rice plants. Their chewing mouthparts are found at the end of a long "snout". The bill bug feeding appears to be injuring the heart of the tiller, causing death of the new leaf (dead heart).
