Medauromorpha regina "Tay Yen Tu", commonly known as the Devil Horned Stick Insect, is a visually striking species native to the Tay Yen Tu region of northern Vietnam. Males are easily recognized by their two prominent black horns and exceptionally long forelegs, which exceed the length of their bodies. Females are bulkier and feature large, leafy lobes on their legs, aiding in camouflage. This species is notable for laying the longest stick insect eggs known—over 15 mm in length. Wingless and sexually reproducing, they feed on plants like bramble, beech, eucalyptus, and oak
