billbug
any stout-bodied beetle of the family Curculionidae (insect order Coleoptera) that has a short snout and body length up to 5 cm (2 inches). Some (e.g., Rhynchophorus) are found mainly in the tropics, boring through the new growth of palm trees. The larvae of R. cruentatus are about 5 cm long and make a clucking sound while boring in cabbage palms. These larvae are eaten, either fried or raw, by native peoples of tropical America. A similar species (R. ferrugines) has threatened copra (dried coconut meat) production in the Pacific because it attacks coconut and wine palms
