Heterochaeta orientalis, often called the Cat-Eye Mantis or Giant African Stick Mantis, is a remarkable species belonging to the family Toxoderidae. Native to much of sub-Saharan Africa, it has been recorded in countries such as Ethiopia, Tanzania, Mozambique, Namibia, Zambia, South Africa, Nigeria, and Senegal. Its elongated body and twig-like appearance make it one of the most convincing examples of stick mimicry among mantids, allowing it to blend seamlessly into scrubland and woodland habitats. Adults can reach lengths of 10–12 cm, with their long thorax and abdomen giving them a spindly, branch-like silhouette.
 
In the wild, H. orientalis is a solitary ambush predator, relying on camouflage to remain undetected until prey comes within reach. It feeds primarily on flying insects such as moths, flies, and small grasshoppers, using its speed and powerful forelegs to snatch prey from the air or foliage. When threatened, it performs a dramatic deimatic display, flashing its amber and red wings to startle potential predators—a striking contrast to its otherwise cryptic appearance. This behaviour highlights its dual survival strategy: stealth for hunting and intimidation for defense.
