They average about 6.5 inches in length, but can reach up to 8". They are very colorful and many keepers believe they are one of the most beautiful of the centipede species. They are the prize of many collectors and make a wonderful showpiece in a display. These desert centipedes range from the southwest United States to northern mexico. There are three subspecies of Giant Desert Centipede. They vary in coloration and distribution. Perhaps the most familiar is the Giant Red-headed Centipede Scolopendra h. castaneiceps, as pictured above. This species has a beautiful black body contrasted with a red head and yellow legs. The other two subspecies are quite attractive as well. The Giant Black-tailed Centipede (Blue-tailed Centipede) Scolopendra h. heros is all yellowish in color, but with a contrasting blue or dark blue, almost black tail. The Giant Arizona Desert Centipede (Black-headed Centipede) Scolopendra h. arizonensis has a black head and tail, contrasted with a red or dark orange body and yellow legs The Giant Desert Centipedes are hardy and easy to keep. This is a relatively calm species of centipede and its venom is not considered deadly. It is handled by experienced keepers, but it can give a very painful bite. We do not recommend handling any centipedes. Caution: The bite of all large centipedes are potentially medically serious, especially so to small children.

Scientific NameScolopendra heros
Subspecies:
- Giant Red-headed Centipede Scolopendra heros castaneiceps
- Giant Black-tailed Centipede, Blue-tailed Centipede Scolopendra heros heros
- Giant Arizona Desert Centipede, Giant Black-headed Centipede Scolopendra heros arizonensis
Habitat: Distribution/BackgroundThe Giant Desert Centipede Scolopendra heros was first described by Girard in 1853. The Giant Desert Centipede is found in the southern United States and in northern Mexico. Other common names this centipede is known by are Giant Sonoran Centipede and Giant North American Centipede. These are terrestrial invertebrates that live under stones and wood, in crevices, and in litter and soil. They will burrow some, staying underground on warm days and emerging in cloudy weather. They are carnivorous and feed on insects, lizards, frogs, and rodents in the wild..
Three subspecies were named by G. Attems in 1931. They are the Giant Red-headed Centipede Scolopendra h. castaneiceps, Giant Black-tailed Centipede, Blue-tailed Centipede Scolopendra h. heros, and the Giant Arizona Desert Centipede, Giant Black-headed Centipede Scolopendra h. arizonensis.
Status The Scolopendra heros is not on the IUCN Red List for Endangered Species.
Description The Giant Desert Centipedes have 26 to 30 segments (generally 26), and the first three to five segments are smooth. The head is finely punctuated with two faint sulci, or grooves. The first pair of legs have two tarsal spines and all of the rest have only one. They can reach 7 to 8" (18 - 20 cm) as adults. Descriptions of the three subspecies of Giant Desert Centipede:

- Giant Arizona Desert Centipede
Giant Black-headed Centipede
Scolopendra h. arizonensis
(pictured above)
This is a red or dark orange centipede with yellow legs and a black head and tail. It is found in Arizona and Mexico. Some of the Arizona specimens have black bands running across the tergites, parallel to the legs. - Giant Black-tailed Centipede
Blue-tailed Centipede
Scolopendra h. heros
This is a yellow centipede with light yellow legs and a medium to dark blue tail. It is found in New Mexico, east to Texas and northern Mexico. - Giant Red-headed Centipede
Scolopendra h. castaneiceps
This is a jet black centipede with a red head and yellow legs. It is found in New Mexico across the southwestern United States and as far north as Kansas and east to Georgia..
Food and FeedingSmall juveniles will eat pinhead crickets or other small insects. As adults they will feed on prey that is not larger than themselves, including large crickets, cockroaches, and even pinky or fuzzy mice. It is generally suggested however, that you don't feed prey that is more than half the length of the centipede. Feed crickets and roaches once a week. Once a month feed a small pink mouse. Keep in mind that overfed invertebrates, and especially overfed centipedes, seem to die much sooner than those that are kept "lean and mean".
HousingA large enclosure that offers plenty of floor space and a deep (4"+) substrate of damp sand and peat moss is ideal. This species will spend most of its time buried in the substrate with only the tips of the back legs or its antennae above ground. Also offer a few well-placed pieces of cork bark, bark, or a sturdy slate shelter to keep specimens settled.
Temperature and humidity requirements:
As typical of a desert species, the Giant Desert Centipede will do fine in the 80° to 85° F range and with a humidity of 50 to 65%. For more information on environment setup, see: Centipede and Millipede Care
Cage CareA good habit to get into is cleaning up any uneaten prey items the day after feeding your centipede as decaying organic matter commonly attracts mites, fungus, mold and other potentially harmful organisms into the enclosure. If your pet has recently molted, remove uneaten prey items immediately. Newly molted centipedes are vulnerable until their exoskeletons hardens.
BehaviorWhen first introduce to its new enclosure, the centipede will often explore the entire area. But once settled in, it will spend most of its time buried in the substrate. All you will see are the tips of the back legs or its antennae above ground. Though they remain hidden by day, the enclosure can be fitted with a red or blue bulb to be turned on at night to watch the centipede foraging for prey and exploring its surrounding.
Handling We do not recommend handling any centipedes. Despite photos of "daredevils" handling large specimens, all Scolopendra are capable of delivering a very painful venomous "pinch". Large specimens should be considered medically serious and some people with reactions to insect venom and those with small children should be very cautious when keeping large Scolopendra species.
Reproduction There is no copulation for centipedes to reproduce. Rather centipede males deposit a spermatophore for the female to find and take up, which then fertilizes the eggs. For species In temperate areas eggs are laid in the spring and summer, but in subtropical and tropical areas they seem to be laid most anytime of year.
Diseases: Ailments/TreatmentsGiant Desert Centipedes have relatively few common health issues as long as they are fed properly, housed in an escape proof enclosure with proper humidity levels, and the cage is kept free of decaying organic matter. Centipedes will feed on a variety of prey including grasshoppers, moths, worms, and even small vertebrate prey, but be cautious of any prey that is captured in nature as they may be carriers of internal parasites. Keep in mind that overfed invertebrates, and especially overfed centipedes, seem to die much sooner than those that are kept "lean and mean". Newly molted centipedes are vulnerable until its exoskeleton hardens, so should have uneaten prey removed immediately.
Availability The Giant Desert Centipede is commonly available in the spring and summer from invertebrate collectors in the Southwestern United States. From these collectors they get spread to dealers throughout the country and they are usually inexpensive. They are hardy and easy to keep and will no doubt be captive-bred in the future.
