The praying mantis, with its distinctive posture and predatory reputation, is a common and fascinating insect often encountered in gardens. Many people wonder if it is safe to interact with them directly. Touching a praying mantis is generally safe for humans, provided the interaction is handled with care and respect for the animal. Understanding the mantis’s natural defenses and how to approach it correctly ensures a positive experience.
Assessing the Physical Risks
Praying mantises are not venomous and do not possess a sting, eliminating the most serious risks associated with insect contact. Their primary tools are large mandibles and powerful, spine-lined forelegs, which they use to capture and hold prey. These raptorial forelegs are designed to secure smaller insects, not to cut or pierce human skin.
The spines on the forelegs can cause a minor, momentary prickling sensation if the insect grasps a finger, which may happen if it mistakes the finger for a perch. Bites are infrequent and usually only occur if the mantis feels trapped or is actively feeding. A bite from a large species might cause slight, temporary discomfort, similar to a minor pinch. However, bites are not medically significant and rarely break the skin deeply, as mantises are highly unlikely to mistake a human for prey.
Proper Handling and Interaction
Interacting with a praying mantis should always prioritize the insect’s welfare, as they are fragile creatures that can be easily injured. The safest method for handling is encouraging the mantis to walk onto an outstretched hand, often called the “walk-on” method. Present a flat hand or a small stick gently in front of the mantis’s path, allowing it to climb aboard at its own pace.
Movement should be slow and deliberate, as quick motions can startle the insect and cause it to flee or become defensive. If the mantis is hesitant, a gentle tap on one of its hind legs can prompt it to move forward. Avoid grabbing the mantis by its body, especially the abdomen or thorax, as this can easily damage its delicate exoskeleton. Refrain from handling a mantis while it is actively feeding or preparing to molt, as it will be stressed and vulnerable.
Understanding Common Mantis Behavior
When a praying mantis feels threatened, it often engages in a defensive posture known as a “Threat Display” or deimatic behavior. This display is meant to startle a potential predator into retreating, not to initiate an attack. The insect rapidly raises its raptorial forelegs and sometimes spreads its wings to appear larger and more intimidating.
Many species also possess conspicuous, brightly colored patches, or “eyespots,” on their wings or inner forelegs that are suddenly revealed during this display. This action is a bluff and a warning, indicating the mantis is stressed and wants to be left alone. If a mantis exhibits this behavior, slowly withdraw your hand and give the insect space. Mantises are generally non-aggressive toward humans, relying on camouflage and stillness as their primary defense until a threat forces a display.
