Neohirasea maerens is a compact, spiny phasmid native to Vietnam, known in the hobby as the Vietnam Prickly Stick Insect. It belongs to the Lonchodidae family and carries the characteristic thorn‑like tubercles that give the genus its textured, armoured appearance. Despite the defensive look, it’s a gentle, slow‑moving species that relies on camouflage and stillness rather than speed.

In the wild, N. maerens inhabits humid forest understorey, where its mottled brown body blends seamlessly with bark and leaf litter. Captive observations note a tendency to remain low in enclosures, reflecting its terrestrial habits. Females produce sturdy, sculpted eggs typical of the group, and the species has been referenced in several phasmid studies for its morphology and defensive chemistry.

Within collections, it’s appreciated for being hardy, understated, and visually interesting without being large or demanding. Its prickly silhouette makes it instantly recognisable, and its calm behaviour suits both display and educational contexts.
