Key Visual Features
Giant centipedes (genus Scolopendra) are among the largest centipedes encountered, and their proportions make them fairly easy to distinguish from smaller house centipedes.
- Size: Commonly 6–8 inches (15–20 cm) long, with some species and individuals reaching more.
- Color: Varies by species but often shows bold banding — combinations of reddish-brown, orange, yellow, or dark brown segments, sometimes with contrasting yellow legs.
- Body shape: Long, flattened, and segmented, built for fast movement along the ground and through crevices.
- Legs: One pair of legs per body segment (typically 21 or 23 pairs depending on species), with the rearmost pair often elongated and trailing behind like a second set of antennae.
- Wings/antennae: No wings; a single pair of long, forward-facing antennae at the head end.
- Markings: Distinct segment-by-segment coloring or banding is common, along with a hardened, glossy-looking exoskeleton.
Where and When You'd See Them
Giant centipedes favor warm, humid climates and are found under logs, rocks, loose bark, and leaf litter, as well as in burrows they dig themselves. They are primarily nocturnal, hunting after dark and retreating to cover during daylight. Activity peaks in warm, humid months, and they may be seen after rain when moisture drives them to move across open ground.
Similar-Looking Bugs
- House centipedes are much smaller, have far longer and more delicate legs relative to body size, and a shorter body overall.
- Millipedes have two pairs of legs per body segment rather than one, move more slowly, and typically have a rounded, not flattened, cross-section.
- Wireworms (beetle larvae) are segmented and elongated but have only six true legs near the head and lack the many leg pairs of a centipede.
- Smaller centipede species share the basic body plan but lack the large size and often the bold banded coloring of true giant centipedes.
Quick ID Checklist
- Long, flattened, segmented body, often 6–8 inches or more
- One pair of legs per segment, with the last pair elongated and trailing
- Single pair of long antennae at the head
- Bold banded coloring in reds, oranges, yellows, or browns
- Found under logs, rocks, and leaf litter in warm, humid habitats, active at night
Frequently asked questions
How many legs does a giant centipede have per segment?
Just one pair of legs per body segment, which is a key difference from millipedes that have two pairs per segment.
What is the easiest way to tell a giant centipede from a millipede?
Look at the body shape and leg count — centipedes are flattened with one leg pair per segment, while millipedes are rounder in cross-section with two leg pairs per segment and move more slowly.
When are giant centipedes most active?
They are primarily nocturnal and most active during warm, humid conditions, often seen after rainfall.
Do giant centipedes have long legs at both ends?
They have long antennae at the front and an elongated final pair of legs at the rear that can look similar to antennae, which sometimes causes confusion about which end is which.
