Sphaerobelum sp. 'Orange Butt' — Orange Butt Giant Pill Millipede

The Orange Butt Giant Pill Millipede is a glossy, rounded pill millipede with a contrasting orange rear section, making it a strong choice for keepers who want something visually striking but not especially surface-active. Identified here as Sphaerobelum sp. 'Orange Butt', it is best bought for its compact, armoured look and unusual appearance rather than for frequent viewing.

If you are comparing pill millipedes, this species is suited to people who like a smaller, heavily plated millipede with clear character and are happy if it spends much of its time out of sight. Its appeal is in the shape, finish and contrast more than constant activity.

A closer look at this millipede

Giant pill millipedes are known for their ability to curl into a defensive ball, and this species has the same rounded, armoured build. The body is thick and domed, with a polished look and a distinct orange rear section that gives it a very recognisable appearance.

Like many pill millipedes, it will often spend time beneath the substrate rather than staying out in the open, so it suits keepers who value unusual form and behaviour as much as day-to-day visibility. New arrivals may also take time to settle and stay hidden at first, which is normal for this kind of millipede.

Colour, pattern and texture

The features you will notice most are the glossy body, rounded plating and strong contrast at the back. The segments have a smooth, armoured finish, while the orange rear section is the detail that makes this species stand out on arrival.

That combination gives the millipede a neat, sculptural look that feels different from more subdued species. If you want a pill millipede with obvious visual character, this is one of the more memorable options.
