The name comes from the Greek word meaning prophet because they appear to be praying when their forelegs are clasped together. They are carnivorous and are equipped with sharp spines along their front legs to grasp prey. The mantis is a very unique insect in that it can turn its head 180 degrees, has only one ear and some are large enough to capture humming birds. Each model features AMAZINGLY detailed laser etching and averages 8-12 pieces laser cut onto a 4" square sheet of thin metal. Easy to follow instructions are included. Makes an excellent gift for tween boys and men of all ages with average assembly time only 30 - 45 minutes!
