The Spiny Devil Walkingstick (Eurycantha horrida) is a well-camouflaged stick insect from Papua New Guinea. This insect looks to imitate a piece of baric and is also known as New Guinean land lobster. Its body is 10 to 12 cm in length and has an oily sheen. The body is covered in small spines. Males have a large ‘spur’ on the inside of each femur, which they use to defend themselves against an attack or during competition with other males. There are reports that in captivity adult males and females of the Spiny Devil Walkingstick form bonds if kept together for the period of a year or longer. If one dies, the surviving insect not only stays with the corpse for a few days afterwards but sometimes the survivor refuses to eat or drink and dies as well.
The photographed male is the only specimen of this species available in the Manchester Museum; collected from New Guinea.
