house centipede?

Surprisingly, I've never seen one of these in real life. I have had the pleasure of having millipedes wind up in my house though.

Have you seen the house centipede (Scutigera coleoptrata)?

I have now

Yes, in photos/videos

Yes, irl

I'm not sure

Whenever I hear people refer to bugs as “uncharismatic”, it makes me feel sad :<

[creatureimages]

the most wonderfully calm and polite allothereua maculata i have ever met. usually they're incredibly scrambly and run around in an understandable panic but this guy was chilling in a crevice in some fallen bark. wonderful.

Open Your Home to the Common House Centipede

A common sight in homes throughout Europe, Asia, the Americas, and Australia the common house centipede (Scutigera coleoptrata) is a medium-sized species of centipede originally from the Mediterranean. In the wild, they prefer grasslands and deciduous forests where they can hide under rocks, logs, or leaf litter. These insects have also adapted well to urban development, and are frequently found in basements, bathrooms, and garages,  as well as gardens and compost piles.

Like other centipedes, the common house centipede has less than 100 legs; in fact, they only have 15 pairs, with the front pair used only for holding prey or fending off threats. All those legs let the common house centipede move up to 0.4 meters per second (1.3 ft/s) over a variety of surfaces, including walls and ceilings. The actual body of S. coleoptrata is only 25 to 35 mm (1.0 to 1.4 in) long, but the antennae are often as long as the body which can give this insect a much larger appearance. However, they can be hard to spot, especially in their natural environments; their tan and dark brown coloration allows them to blend in seamlessly to surrounding vegetation.

Though they pose little threat to humans, house centipedes are predatory. Their primary food source is other arthropods, including cockroaches, silverfish, bed bugs, ticks, ants, and insect larvae. S. coleoptrata is a nocturnal hunter, and uses its long antennae to track scents and tactile information. Their compound eyes, unusual for centipede species, can distinguish daylight and ultraviolet light but is generally used as a secondary sensory organ. When they do find prey, house centipedes inject a venom which can be lethal in smaller organisms, but is largely harmless to larger animals. This makes them important pest controllers. In the wild, house centipedes are the common prey of rodents, amphibians, birds, and other insects.

The mating season for S. coleoptrata begins in the spring, when males and females release pheromones that they can use to find each other. Once located, the male spins a silk pad in which he places his sperm for the female to collect. She then lays fertilized eggs in warm, moist soil in clutches of 60-150. These eggs incubate for about a month, and the young emerge with only four pairs of legs. Over the next three years, juvenile house centipedes molt 7 times, each time gaining new pairs of legs. After they grow their last pair of legs, immature house centipedes molt an additional 3 times, at which time they become sexually mature. If they can avoid predation, individuals can live up to 7 years in the wild.

Conservation status: The common house centipede has not been evaluated by the IUCN, as it is relatively common both in the wild and in urban areas. Although they have been introduced to areas outside their native range, no detrimental environmental effects have been associated with their spread.

Young house centipedes are born with four pairs of legs (eight legs total) and with subsequent molts will gain new legs until they eventually reach 15 pairs of legs (thirty legs total). Isn’t that wild? At the time they reach 15 pairs of legs they are considered an adolescent and will go through four more molts before they become an adult. Females can survive for several years. They are nocturnal and feed on a wide variety of insects.

They are originally native to the Mediterranean but were accidentally introduced into the southern United States.

Thereuonema tuberculata, east asian Scutigeromorph centipede thats (relatively recently) been identified as pretty widely present in the eastern US, with a range stretching from the east coast to as far west as Oklahoma and Nebraska. Most likely they’ve been present for decades and just always misidentified as Scutigera coleoptrata. They generally seem to partition with Scutigera by preferring outdoor habitats, and in the warmer months you can even find them perched up on trees at night, waiting for dinner (delicious moth or hemipteran)
