What insect can turn its head 180 degrees to look over its shoulder?

The insect that can turn its head nearly 180 degrees to look over its shoulder is the praying mantis. Its unusually flexible neck lets the triangular head swivel while the rest of the body remains relatively still.

This ability is valuable for a predator that often waits motionless for prey. A mantis can scan its surroundings and track movement without turning its entire body, helping it remain concealed. Its large compound eyes also provide excellent visual detection, especially for movement.

The head movement is often described as 180 degrees, though “nearly 180 degrees” is the more precise scientific wording and varies among species. The mantis is not literally looking backward through a rotating head joint like an owl; its flexible cervical region allows a wide side-to-side rotation.

Praying mantises are also recognized by their raptorial front legs, which fold into a prayer-like posture and seize prey with spines. They are sometimes confused with stick insects or grasshoppers, but those insects lack the mantis’s distinctive neck mobility and grasping forelegs.
