Yellow-tailed scorpion
The yellow-tailed scorpion, scientifically classified as Euscorpius flavicaudis, is a species native to southern Europe and northwest Africa, with a significant population in the United Kingdom, where it arrived via ship cargo. Recognizable by its large, segmented yellow tail, this scorpion typically measures between one and two inches (2.5 to 5 centimeters) in length. Unlike many scorpion species, the yellow-tailed scorpion's venom is harmless to humans, primarily serving to subdue its insect prey, which includes spiders and flies.
These ground-dwelling creatures prefer damp hiding spots, such as under stones or logs, and may occasionally be found in human dwellings. They exhibit nocturnal behavior, hunting at night either actively or via ambush. Interestingly, yellow-tailed scorpions may also engage in cannibalism. They reach sexual maturity in about seven to eight months, with a unique courtship ritual involving a circular dance. After mating, the female gives birth to approximately 30 live young, around 10 months later. With a lifespan of up to five years, the yellow-tailed scorpion is not considered threatened, highlighting its adaptability in various environments.

Yellow-tailed scorpion
The yellow-tailed scorpion is native to southern Europe and northwest Africa. A large yellow-tailed scorpion population exists in the United Kingdom. The yellow-tailed scorpion is named for its large, segmented, yellow tail. Although some scorpions contain venom in their tails which is deadly to humans, the venom of the yellow-tailed scorpion is harmless to humans and only deadly to the prey of this ground-dwelling creature.
Kingdom: Animalia
Phylum: Arthropoda
Class: Arachnida
Order: Scorpiones
Family: Euscorpiidae
Genus: Euscorpius
Species: Flavicaudis
The yellow-tailed scorpion may be found throughout southern Europe along the countries connected to the western Mediterranean Sea including Spain, southern France, Corsica, Italy, and Algeria. This scorpion is also found at altitudes of up to 6,500 feet (1,950 meters) in the Alps. A large population of yellow-tailed scorpion is found throughout the United Kingdom where it arrived along with a ship's cargo.
Typically, the yellow-tailed scorpion spends the day hiding in damp places such as under a stone or log. In areas near humans, the yellow-tailed scorpion may also be found hiding in clothes, beds, and under carpets. At night the yellow-tailed scorpion comes out from its hiding place to hunt for spiders, flies, moths, and other insects. The yellow-tailed scorpion may hunt actively or may hunt by waiting for unsuspecting prey. When the yellow-tailed scorpion senses prey it reaches out with its sharp pincers and begins to tear its prey apart. Prey that is too large to be overcome by the pincers, may be sprayed with venom from the yellow-tailed scorpion's tail. Since the yellow-tailed scorpion does not have strong mouthparts, it must tear its food into small pieces before eating.
The yellow-tailed scorpion may grow to be between one and two inches (2 1/2 to five centimeters) long. Its body, as well as its tail, is a clear, yellowish color. The claw-like pincers of the yellow-tailed scorpion extend from the front of the yellow-tailed scorpion's cephalothorax. The cephalothorax is the head and thorax, or mid-body section of the yellow-tailed scorpion. The eight legs of the yellow-tailed scorpion each extend from different segments of the cephalothorax.
Behind the cephalothorax is the abdomen, or lower-body section, of the yellow-tailed scorpion. This part contains all of the internal organs of the yellow-tailed scorpion and also includes the segmented tail of this arachnid. This tail contains venom which the yellow-tailed scorpion uses mostly to defend itself against predators such as birds, lizards, and mammals. The venom of the yellow-tailed scorpion is not strong enough to harm humans.
The yellow-tailed scorpion is an ambush predator who eats wood lice and other small insects. Yellow-tailed scorpions have been known to engage in cannibalism, or eating other yellow-tailed scorpions.
The yellow-tailed scorpion becomes sexually mature when it is seven to eight months old. The ritual of courtship begins with the male facing the female and grabbing her claws with his claws. The two then begin to dance in a circle. As they dance, the male searches for a smooth area of ground on which he deposits a spermatophore, or capsule of sperm. The male then positions the female over the spermatophore and she pulls it into her body. The male then releases the female and quickly moves away to avoid her aggressive behavior. The fertilized eggs develop within the female. About 10 months after mating, the female yellow-tailed scorpion gives birth to 30 live young. Typically, mating between yellow-tailed scorpions takes place during the warm months of the year.
The yellow-tailed scorpion has a life span of up to five years. The yellow-tailed scorpion is not considered a threatened species.
