Rusty Millipede

Trigoniulus corallinus

Also known as Common Asian Millipede, Red Millipede

Rusty millipedes thrive in humid microhabitats, breaking down fallen leaf litter and decaying plant matter into nutrient-rich soil. When threatened, they curl into tight defensive spirals and release foul-tasting benzoquinone secretions from side pores to deter predators. Native to the Indo-Malayan region, these vibrant arthropods have successfully colonized tropical and subtropical gardens around the globe.

Why interaction risk is low
Emits defensive chemical fluids that stain skin and irritate eyes; wash hands after touching.
Why it is dangerous
Secretes benzoquinone compounds when stressed, causing temporary skin staining and mild burning if rubbed into eyes.
How to recognize a risky encounter
Recognized by its uniform brick-red to bright orange-red body and smooth cylindrical segments.
What to do
Avoid squeezing or handling roughly, and wash hands promptly after contact.
Responsible observation
  • Spotting in Gardens: Turn over damp logs, leaf litter, and potted plant saucers in warm, humid weather.
  • Safe Handling: Allow the millipede to walk across an open palm rather than grasping or pinching its body.
