9 Types of Centipedes in New York: Complete Identification Guide with Photos

Did you know that centipedes are actually not insects but belong to the Chilopoda class and are small arthropods?

While these many-legged creatures might send shivers down your spine, understanding the different types of centipedes in New York can help you identify what’s crawling around your home and determine whether they pose any real threat.

New York’s diverse climate and varied ecosystems provide ideal habitats for numerous centipede species, from the lightning-fast house centipede darting across your bathroom floor to the soil-dwelling giants lurking beneath garden beds.

This comprehensive guide will help you identify nine distinct centipede species found throughout the Empire State, understand their behaviors, and learn practical management strategies.

Understanding Centipede Basics in New York

Before diving into specific species, it’s essential to understand what makes centipedes unique.

The class is further broken down into four orders identified as Scutigeromorpha, Scolopendromorpha, Lithobiomorpha and Geophilomorpha, each differed by varying leg segments and total number of legs.

Key Centipede Characteristics:

• One pair of legs per body segment
• Predatory arthropods that hunt other insects
• Range from harmless household helpers to potentially concerning biters
• Active primarily during nighttime hours

Safety Note: While most New York centipedes are harmless to humans, some species can deliver painful bites. Always exercise caution when handling or encountering unknown centipede species.

1. House Centipede (Scutigera coleoptrata)

The house centipede stands as New York’s most commonly encountered centipede species. Scutigera coleoptrata, also known as the house centipede, is a species of centipede that is typically yellowish-grey and has up to 15 pairs of long legs.

Physical Characteristics:

• Length: 1 to 1.5 inches
• Color: Yellowish-grey with dark stripes
• 15 pairs of slender legs that are encircled by dark and white bands
• Distinctive long antennae and compound eyes

Habitat and Behavior: House centipedes prefer moist environments and are frequently found in basements, bathrooms, and other humid areas of homes. They move with incredible speed and are beneficial predators, hunting cockroaches, silverfish, and other household pests.

Identification Tips:

• Extremely fast movement when disturbed
• Long, striped legs that break off easily when grabbed
• Often seen running along walls and ceilings
• Most active during nighttime hours

Homeowner Benefit: House centipedes are actually beneficial, as they actively hunt and eliminate many common household pests including cockroaches, moths, and silverfish.

2. Eastern Red Centipede (Scolopocryptops sexspinosus)

Scolopocryptops sexspinosus, the eastern red centipede, is a species of centipede in the family Scolopocryptopidae found in North America. This species represents one of the more impressive centipedes found in New York.

Physical Characteristics:

• Length: 2 to 4 inches
• Color: Reddish-brown body with bright yellow legs
• Flattened body structure
• Powerful mandibles for capturing prey

Habitat and Behavior: Eastern red centipedes prefer outdoor environments, living under rocks, logs, and leaf litter. The Eastern Red Centipede is known for its agile nature and lightning-fast stride. Since their bodies are more flattened than other species, they can easily maneuver through the smallest areas.

Caution Level: This species can deliver painful bites to humans, though they are not dangerous. They are aggressive hunters and will bite if handled or threatened.

3. Stone Centipede (Lithobius forficatus)

The Brown Centipede (Lithobius forficatus) is also known as the stone centipede and is common in Europe, though it is distributed throughout the world. This hardy species has established populations throughout New York.

Physical Characteristics:

• Length: Up to 30mm (approximately 1.2 inches)
• Color: Chestnut brown
• 15 pairs of legs
• Relatively robust body structure

Habitat and Behavior: Stone centipedes live in the upper layers of soil, under rocks, and in rotting wood. They are excellent hunters of small insects and play important ecological roles in garden environments.

4. Soil Centipede (Geophilus spp.)

Soil centipedes represent multiple species within the Geophilus genus found throughout New York. These creatures are a bit flatter than most centipedes. Since they spend most of their time underground, Soil Centipedes have no eyes.

Physical Characteristics:

• Length: 1 to 2 inches
• Color: Yellowish to light brown
• Eyeless (adapted for underground life)
• Worm-like movement pattern

Unique Behaviors:

• They move through the soil like an earthworm, pushing the front of their body forward and dragging the back towards it before repeating the process
• Rarely seen above ground
• Important soil ecosystem contributors

5. Eastern Bark Centipede (Hemiscolopendra marginata)

The eastern bark centipede represents a lesser-known but significant species in New York’s centipede diversity. These centipedes typically inhabit wooded areas and are found under bark and rotting logs.

Physical Characteristics:

• Length: 2 to 3 inches
• Color: Dark brown with lighter margins
• Robust build with powerful legs
• Well-developed sensory organs

Habitat Preferences:

• Deciduous and mixed forests
• Under loose bark of dead or dying trees
• Moist woodland environments
• Occasionally found in suburban areas with mature trees

6. Cryptopid Centipede (Cryptops hortensis)

Cryptops hortensis represents a group of small but significant centipedes found throughout New York’s diverse habitats.

Physical Characteristics:

• Length: 0.75 to 1.5 inches
• Color: Golden brown to dark brown
• Compact, robust body
• 21 pairs of legs

Ecological Role: These centipedes serve as important predators of small soil invertebrates and contribute significantly to ecosystem balance in gardens and natural areas.

7. Lilliputian Centipede (Strigamia spp.)

Despite their diminutive name, Lilliputian centipedes play crucial roles in New York’s soil ecosystems.

Physical Characteristics:

• Length: 0.5 to 1 inch
• Color: Pale yellow to light brown
• Thread-like appearance
• Numerous leg pairs (up to 50+)

Habitat and Behavior:

• Deep soil dwellers
• Feed on small soil organisms
• Important decomposer ecosystem contributors
• Rarely encountered by homeowners

8. Meadow Centipede (Stigmatogaster subterranea)

Meadow centipedes inhabit New York’s grasslands and suburban areas, contributing to natural pest control.

Physical Characteristics:

• Length: 1 to 2 inches
• Color: Light brown with darker segmentation
• Slender build
• 15 pairs of legs

Behavior and Benefits:

• Active hunters of lawn pests
• Important in maintaining healthy grass ecosystems
