Siamese Glow Millipede (Benoitolus siamensis)

The Siamese Glow Millipede (Benoitolus siamensis) is a slender Thai millipede with a dark, segmented body and UV-induced fluorescence. It is a good choice for keepers who want a visually unusual species that rewards close observation.

The key feature is simple: the glow appears under ultraviolet light, not in normal room lighting. That makes this a millipede for keepers who value the viewing experience as much as the animal itself.

This species sits within our UV Glow Millipedes collection. If you are comparing options, you may also want to look at the Khao Sok Glow Millipede (Benoitolus sp. "Khao Sok") and the Hawaiian Glow Millipede (Spirobolellus sp. "Maui") to judge which glow-type species best fits your setup and expectations.

Is the Siamese Glow Millipede right for your setup?

This species suits keepers who want a refined, slender millipede rather than a bulky showpiece. It is a better fit if you are interested in close observation and in the novelty of UV fluorescence, rather than simply buying a millipede for size or colour alone.

Have your enclosure ready before it arrives. A suitable setup should include deep, organic substrate, moisture, decaying plant material and hiding places. New arrivals often stay below the surface while they settle, so a quiet start and minimal disturbance are important if you want the animal to settle well.

If you are still deciding, our Millipede Species Guide is useful for understanding how different species vary in appearance and keeper expectations. You can also browse our broader Millipedes for Sale UK collection if you are comparing other options.

What to expect once it arrives

When your Siamese Glow Millipede arrives, it may spend time hidden in the substrate at first. That is normal and usually just means it is settling into a new environment.

In day-to-day conditions it appears as a dark, glossy, neatly segmented millipede. The fluorescent effect is best appreciated under UV light, so this is a purchase for keepers who want a species with a distinctive visual payoff rather than a constantly bright display animal.

If that sounds like the sort of millipede you want to keep, the Siamese Glow Millipede is a confident and unusual choice.
