Archaeology
According to The Journal of Orthoptera Research, in 2017-2018, a rock carving of a six-legged mantis named Empusa hedenborgii with raptorial forearms was revealed in the Teimareh rock-art site. An engraved, insect-like image has a 14cm length and 11cm width, with two circles at its sides that probably dates 40,000–4,000 years ago. This motif is analogous to the famous "squatter man" petroglyph encountered at several locations around the world.
