Flat and dark Scolopendrid Centipedes are sluggish soil dwellers that occasionally wander indoors.
Scolopendrid Centipedes are commonly found in leaf litter, under wood and stones, or even wandering the ground. They are like other centipedes, having the same flexibility and segmentation. This species has some color variation among individuals. Some are black or a bluish-gray, while other appear more green or yellowish. They move underground like worms, stretching their bodies and contracting them, eating invertebrates they find in the soil. They also move above ground hunting other small insects.
Scolopendrid Centipedes produce venom and they use it to dispatch their prey. They may bite people if handled roughly. These bites are painful, but not life threatening; that said, medical attention may be helpful if symptoms from the bite do not diminish in a few days. If found indoors and live capture is possible, releasing Scolopendrid Centipedes into the garden helps control pest insects.

Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
