This Chinese mantid (Tenodera aridifolia) bit my finger in broad daylight this afternoon. Well, OK, I provoked it. I had been taking its pictures in my backyard and a couple of times when I came too close to it, it actually jumped on the camera. Those were probably preemptive strikes to warn me to stay away, but it didn't dawn on me that this was one brave mantid. So finally, when I reached out to re-position it on the branch it was sitting, it jumped on the index finger of my left hand, grabbed it with its spiny front legs and started biting it repeatedly. I continued photographing it until it gave me one painful bite and punctured my skin. That made me shake my hand and the mantid let go.
When I took one last picture of it as it was slipping away, it turned to give me one final look. My face is probably burned in its memory now.
