Mantis are kinsmen with cockroaches. They have a very good camouflage and can stay still for a long time. The body length of most of them is between 40 and 80 mm. The smallest mantis is represented by the Mantoida genus from South America, the smallest of which is Mantoida tenuis – only 12 mm. The largest ones are Toxodera and Ischnomantis with almost 160 mm.
Most mantis, such as Phyllocrania paradoxa and Hymenopus coronatus, are active during the day. They wait for a long time until their victim approaches and grabs her with their tentacles. Other species such as Popa spurca, Eremiaphila and Heteronutarsus, who live in deserts and semi-deserts, run very fast, pursue the prey and surround it. Besides insects and spiders they can capture scorpions, small snakes, hummingbirds and small mammals.
