Damage Damage depends on the type of mouthpart Chewing-tear, chew or grind food Sucking: Piercing: punctures plant and suck sap Rasping: rasps or break surface and suck sap. Siphoning: have a coiled tube they dip into liquid food such as nectar and draw it in (ex. Butterfly) Sponging: have two sponge-like structures that collect liquid food and move it into the food canal. (ex. House fly)
