Yellow-Spotted Millipede

The Yellow-Spotted Millipede, scientifically known as Harpaphe haydeniana, is a striking and vital component of forest ecosystems in the Pacific Northwest of North America. Commonly referred to as the almond-scented millipede or cyanide millipede, this fascinating arthropod is famous for its dramatic defense mechanism: when threatened, it secretes hydrogen cyanide, producing a distinct odor reminiscent of toasted almonds. This toxic secretion, coupled with its stark black and yellow warning coloration, effectively deters most potential predators like birds and small mammals. Beyond its impressive chemical defenses, the Yellow-Spotted Millipede is a crucial ecological engineer. As a detritivore, it spends its days burrowing through leaf litter and decaying wood, breaking down dead plant material and recycling vital nutrients back into the soil. Its presence is a key indicator of a healthy, moist woodland environment, making it a familiar and treasured find for nature enthusiasts exploring the damp, shaded trails of coastal forests.

Hábitat: Found in moist, mature coniferous and mixed forests of the Pacific Northwest, typically hiding under leaf litter, decaying logs, and mossy forest floor debris.
