Eurycantha insularis is a robust, charismatic stick insect species from the humid forests of Papua New Guinea and surrounding islands. Closely related to the more widely known Eurycantha calcarata, this species shares the same heavy‑bodied, armour‑like appearance but is often slightly smaller and more subtly patterned. Their earthy browns, mossy greens, and textured exoskeletons blend seamlessly into leaf litter and bark, giving them a wonderfully prehistoric look.
 
This species is primarily nocturnal and spends much of the day wedged into crevices or buried among foliage, emerging at night to feed. Adults are strong, slow‑moving, and surprisingly expressive, while nymphs are hardy and grow steadily when kept warm and humid. Like other Eurycantha, they are gentle but capable of a defensive kick if startled — more bluff than bite, and easily avoided with calm handling.
 
E. insularis thrives in naturalistic, humid enclosures with plenty of vertical and horizontal structure. They are excellent for keepers who enjoy observing natural behaviours, maintaining lush planted setups, or working with larger phasmids that feel substantial without being demanding. With their impressive build, calm temperament, and low‑maintenance care, Eurycantha insularis is a rewarding species for both newcomers and experienced phasmid enthusiasts.
