Rhombodera stalii is a large, leaf-like mantis native to Southeast Asia, particularly found in countries like Thailand, Vietnam, and Malaysia. Its broad, shield-shaped thorax and vivid green coloration provide excellent camouflage among foliage, making it a stealthy ambush predator. Females are notably robust and sedentary, while males are slimmer and capable of flight. This species thrives in warm, humid environments and feeds readily on a variety of insects.
