Yellow-Spotted Millipede (Harpaphe haydeniana)

Series of top view illustrations of the Yellow-Spotted Millipede

The Yellow-Spotted Millipede (Harpache haydeniana) is a flat-backed millipede species found in the moist forests along the Pacific coast of North America, from Southeast Alaska to California. The upper surface of the body is black or olive green, and it is marked along the sides with yellowish patches. The Yellow-Spotted Millipede has about 20 body segments with a total of 30 or 31 pairs of legs. The species plays an important role in the forest ecosystem by breaking down leaf litter to free the nutrients for other organisms. Due to its aposematic coloration and the ability to secrete hydrogen cyanide, the species has few predators.

The Yellow-Spotted Millipede has an overall length between 1.6”-2” (4-5 cm), width of .24”-.39” (6-10 mm), and weight of .03-.05 oz (.8-1.5 g). The typical lifespan of the Yellow-Spotted Millipede is between 2-3 years.
