Common Centipede
The common centipede that lives in the Pacific Northwest is a brownish red in color with long antennae at the front and a pair of long legs at the back that reach out almost as far as the antennae. The Common centipede can crawl backward almost as easily as it can crawl forwards. Read More….

Narceus Americanus Millipede
Narceus Americanus Millipedes overwinter in rotting logs or in soil. In the spring, they emerge and mate. The females form nests using regurgitated food and then lay a single egg into it. They will brood the egg by wrapping themselves around it. In several weeks it will hatch as a nymph, they will have only three pairs of legs, but more grow with each molt. Read More….
Stone Centipedes
They have a flattened, segmented body, long antennas, and many legs. The centipede’s body is divided into two parts, the head, and a segmented trunk and they breathe through holes in their body. Centipedes have a hard exoskeleton that protects their soft internal organs. Read More….
Centipedes and millipedes can be found all over Vancouver Island. Centipedes can easily be distinguished from millipedes by counting the number of pairs of legs arising from most body segments, millipedes have two pairs, while centipedes bear one pair per segment, with the first pair of legs being modified into fangs.
Centipedes are generally flattened and have a pair of well-developed antennae on the head. Some centipedes, such as the house centipede have long legs and are capable of running rapidly.
The largest centipedes may grow to be about 15 cm long. Millipede bodies are rounded or somewhat flattened. Legs are short and movement is slow, with the movement of legs appearing wave-like. Most species are less than 4 cm long.
Centipedes and millipedes spend the winter as adults in protected habitats and become active in the spring. During the warmer months, females lay eggs in the soil and cover them with a sticky substance, although some species give birth to living young.
Immature stages (larvae) hatching from eggs several days later are similar to adults but smaller, having fewer leg bearing body segments. Additional leg bearing segments are produced with each molt. Millipedes develop through about seven stages in 21 to 25 weeks. Some centipedes are known to live to 6 years.
Centipedes and millipedes prefer to live in moist habitats and during the day hide underneath rocks, logs, and other objects in contact with the ground. They are active at night. Centipedes feed on insects and spiders. They kill by grasping prey with their powerful fangs and injecting venom. The fangs are located on the body segment just below the head. Millipedes feed on decomposing organic matter, but will occasionally damage seedling plants by feeding on leaves, stems, and roots.
