Centipedes have one pair of legs per segment, while millipedes have two. Their heads differ in that millipedes have short, elbowed antennae, a pair of robust mandibles and a single pair of maxillae fused into a lip; centipedes have long, threadlike antennae, a pair of small mandibles, two pairs of maxillae and a pair of large venom claws.

House centipedes lay their eggs in spring. In a laboratory observation of 24 house centipedes, an average of 63 and a maximum of 151 eggs were laid. As with many other arthropods, the larvae look like miniature versions of the adult, albeit with fewer legs. Young centipedes have four pairs of legs when they are hatched.
House centipedes typically have 15 legs and can travel 1.3 feet-per-second, which explains why catching one of these centipedes in house is nearly impossible. The typical response to a house ...
House centipedes are hemianamorphic, [5] and adults in this order have 15 leg-bearing segments. [6] Adults have bodies that measure 2 to 3.5 cm in length, but some can reach 8 cm in body length. [2] Species in this order can be readily recognized by their long legs and antennae. [4]
Scutigera is a centipede genus in the scutigeromorph (house centipede) family Scutigeridae, a group of centipedes with long limbs and true compound eyes (which were once thought to be secondary, re-evolved "pseudofacetted eyes" [1]).
S. polymorpha is indigenous to the Southwestern United States and northern Mexico, north to the Pacific coast. [3] [4] It inhabits dry grasslands, forest, and desert; in these habitats, the centipedes generally take up residence under rocks, though they have been observed creating burrows in suitable environments and inside rotting logs.
This centipede can deliver a painful bite if handled; they feed on spiders, insects, earthworms, and even smaller centipedes. Adults are active throughout the year. [ 5 ] The eastern red centipede is capable of thermoregulating and maintaining performance across a broad range of temperatures.
These centipedes are yellow and may grow up to 45 millimetres (1.8 in) in length. [ 8 ] [ 9 ] They are sightless, and rely on specialised sensory organs to sense movement, humidity and light. [ 10 ] Like other myriapods , they have an exoskeleton and a pair of antennae on their head and rear. [ 11 ]
