Cicadas are benign to humans under normal circumstances and do not bite or sting in a true sense, but may mistake a person's arm or other part of their body for a tree or plant limb and attempt to feed. Cicadas have long proboscises under their heads which they insert into plant stems in order to feed on sap. Bites can be painful if a cicada attempts to pierce a person's skin, but they are unlikely to cause other harm. Bites are unlikely to be a defensive reaction and are rare, usually occurring when a cicada is allowed to rest on a person's body for an extended amount of time.
Cicadas can cause damage to several cultivated crops, shrubs, and trees, mainly in the form of scarring left on tree branches while the females lay their eggs deep in branches.
Many people around the world regularly eat cicadas. They are known to have been eaten in Ancient Greece as well as China, Malaysia,Burma, Latin America, and the Congo. Female cicadas are prized for being meatier. Shells of cicadas are employed in the traditional medicines of China.
