Scutigera coleoptrata is a species of centipede that's often found in homes and buildings. It's native to Mexico and Central America.
These centipedes are typically brown or yellowish in color, and have a distinctive flat, oval-shaped body that's around 1-2 inches long. They have 15 pairs of legs, which they use to move quickly and efficiently.
Scutigera coleoptrata is a nocturnal species, meaning it's active at night and rests during the day. This makes them less likely to be seen during the day, but more active in the evening and at night.

Physical Characteristics
Scutigera coleoptrata, or the house centipede, is a fascinating creature with some remarkable physical characteristics.
Its body is a beautiful shade of brown or black, and it has an exoskeleton made of chitin and sclerotin, which provides excellent protection.
The house centipede's body is flattened from top to bottom and is divided into 15 segments, each with a pair of legs. This is quite unique, as most other centipedes have fewer segments.
The first pair of legs is modified into fangs, which the house centipede uses to capture prey and defend itself.
These fangs are incredibly effective, and the house centipede is known to be a skilled hunter.
The house centipede has three dorsal longitudinal stripes, which give it a distinctive appearance.
Its legs are also banded, adding to its striking visual features.
The house centipede's antennae and compound eyes are highly developed, allowing it to detect even the slightest movements.
It's worth noting that the house centipede is a relatively small creature, ranging from 1 to 6 cm in length.
Here are some key physical characteristics of the house centipede:
- Exoskeleton made of chitin and sclerotin
- Flattened, 15-segmented body
- Modified first pair of legs into fangs
- Three dorsal longitudinal stripes
- Banded legs
- Well-developed antennae and compound eyes
- Length: 1-6 cm
- Quick runner
- Venomous
- Ectothermic
- Heterothermic
- Bilateral symmetry
Behavior and Habitat
Scutigera coleoptrata, also known as house centipedes, are nocturnal creatures that hide in dark, damp, and cool places during the daytime. They tend to thrive in temperate climates and can survive in many humid habitats.
House centipedes can be found in various parts of the house, including basements, bathrooms, and even offices. They often emerge from hiding during watering of gardens or flowerbeds and can be seen crawling along the ground or floor.

In their natural habitats, they can be found under large rocks, piles of wood or leaves, and in compost piles. They're also known to burrow in response to changing environmental conditions such as extreme cold or drought.
Here are some common hideouts of house centipedes:
- Basements
- Closets
- Bathrooms
- Potted plants
- Unexcavated areas under the house
- Under the bark of firewood stored indoors
Behavior
House centipedes are primarily nocturnal hunters, which means they do most of their hunting at night. This is likely due to their sensitive antennae, which help them detect smells and touch.
They use their antennae to sense the environment around them, and in the case of Scutigera coleoptrata, they also make good use of their eyes. This helps them navigate and find prey in the dark.
House centipedes are known to migrate or burrow in response to changing environmental conditions, such as extreme cold or drought. This adaptability is crucial for their survival.
During the day, they retreat to protected habitats like underneath rocks and logs, becoming active at night. This behavior helps them conserve energy and avoid predators.
House centipedes have a unique way of grooming their legs by curling around and cleaning them with their forcipules. This helps keep their legs healthy and free from debris.
Here are some key behaviors associated with house centipedes:
- terricolous (meaning they live in soil or under rocks)
- nocturnal (meaning they are active at night)
- motile (meaning they are able to move around)
Habitat of House Centipedes
House centipedes are often found in damp and cool spots, such as basements, closets, bathrooms, and potted plants. They thrive in humid environments, which is why they're commonly found in areas with high humidity like bathrooms and lavatories.
They can also be found in drier places like offices, bedrooms, and dining rooms. In fact, they're capable of climbing walls and crawling along the ground or floor.
House centipedes typically hide in dark, damp, and cool places during the daytime, but venture out at night to hunt. They often emerge from hiding during the watering of gardens or flowerbeds.
Some common hideouts of house centipedes include:
- Under large rocks
- Piles of wood or leaves
- Barkdust
- Compost piles
- Under the bark of firewood stored indoors
- Unexcavated areas under the house
They're most likely to be encountered in spring, when they emerge due to warmer weather, and in autumn, when the cooling weather forces them to seek shelter in human habitats.

Biological Details
The faceted eyes of the house centipede, Scutigera coleoptrata, are incredibly sensitive to daylight and even more so to ultraviolet light. This is a remarkable ability, considering its nocturnal lifestyle and underground natural habitat.
The eyes are so sensitive that they can visually distinguish between different mutations of Drosophila melanogaster, a type of fruit fly. However, this doesn't mean they instantly change direction when light is shone at them - they'll instead retreat to a darker hiding spot.
Some of the plates covering the body segments have fused and become smaller over time, resulting in a mismatch between body segments and dorsal plates, or tergites. This is the cause of the house centipede's rigid body.
Etymology
The name Scutigera coleoptrata is a mouthful, but it's actually quite telling. It comes from the Latin words scutum, meaning "shield", and gerere, meaning "to bear", which refers to the shape of the plates on the back of the chilopod.

Carl Linnaeus was the first to describe the species in 1758, giving it the name Scolopendra coleoptrata. He noted that it has a "coleopterated thorax", meaning its thorax is similar to that of a beetle.
The name Scutigera was later changed to Scutigera coleoptrata in 1801 by Jean-Baptiste Lamarck, who recognized the species as distinct from Scolopendra.
Development
As we explore the biological details of certain insects, it's fascinating to see how they develop from eggs to mature adults.
The egg stage is a crucial part of an insect's life cycle, and in the case of S. coleoptrata, the young ones hatch from the egg looking surprisingly similar to the adults, but with only four pairs of legs.
These immature insects go through five larval instars, each one gaining more leg pairs as they molt and grow.
During this process, they shed their skin multiple times, a process that's both essential and a bit eerie to think about.
After five molts, these young insects have finally reached maturity, sporting all fourteen pairs of legs and ready to take on the world.

The house centipede's hemolymph contains proteins for transporting oxygen, which is a unique feature among centipedes.
Geographic and Economic Importance
The common house centipede, Scutigera coleoptrata, is native to the Mediterranean region. It has since spread to Europe, Asia, and North America.
This centipede can be found living in the northern part of the Old World, which includes Europe, Asia, and northern Africa. They're quite adaptable and have made themselves at home in many different environments.
House centipedes are a valuable asset to humans, eating many pest organisms like cockroaches and silverfish. They're a natural way to control pest populations, making them a positive force in our lives.
Geographic Range

The common house centipede, Scutigera coleoptrata, has a pretty impressive geographic range. It's thought to be native to the Mediterranean.
Scutigera coleoptrata can now be found throughout Europe, Asia, and North America.
Economic Importance: Positive
House centipedes are beneficial to have around, especially in homes with pest problems. They eat many pest organisms, including cockroaches and silverfish.
One of the main reasons house centipedes are a positive presence is that they help control pest populations. This is a big deal, especially in urban areas where pest infestations can be a major issue.
House centipedes are voracious eaters, consuming many pest insects that can damage homes and spread disease. By controlling pest populations, house centipedes help protect homes and the people who live in them.
Here are some specific examples of the positive impacts of house centipedes:

House Centipedes
House centipedes are the most common centipedes found in the U.S., and they're also known as "hundred-leggers" due to their many pairs of legs.
These centipedes are usually about an inch or two long and have 15 segments, each with a pair of long legs. They're generally dark brown or yellow and sometimes have darker colors and markings.
Adult centipedes have three dark parallel lines running from their head to the rear end of their bodies and a hair-covered pair of antennae on their heads. They also have a pair of legs called forcipules right below their mouths, which they use to discharge a venomous sting at their prey or for self-defense.
House centipedes don't harm humans and are actually beneficial because they help control infestations of other pests like cockroaches and spiders. They're nocturnal creatures that hide in dark, damp, and cool places during the daytime and venture out in the dark to hunt.
To get rid of house centipedes, it's not necessary to exterminate them, but rather to reduce the humidity in your home by using dehumidifiers and fans. You can also eliminate spots and fill in cracks and crevices around the walls in your basement to prevent them from living there.
House centipedes have three life stages: egg, larva, and adult. They lay their eggs in the soil during the summer and the female centipede can lay up to 35 eggs over a few days.
