- Scorpions find their way through sensory structures in their legs, by feeling along with brush-like structures called pectines attached to the underside of the abdomen, and through fine sensory hairs to detect vibrations. Male scorpions also use the pectines to find an available female, and newborn scorpions use them to recognize their mother.

Size: One of the most reliable ways to determine the gender of an Asian forest scorpion is by looking at its size. In general, male scorpions tend to be smaller and more slender than female scorpions.

- Male Vs Female Asian Forest Scorpion
How can you tell the gender of an Asian forest scorpion? One way to differentiate between male and female Asian forest scorpions is by examining their pectines, which are sensory organs located on the underside of their bodies.

scorpion, (order Scorpiones or Scorpionida), any of approximately 1,500 elongated arachnid species characterized by a segmented curved tail tipped with a venomous stinger at the rear of the body and a pair of grasping pincers at the front. Although scorpions are most common and diverse in deserts, they also live in many other habitats. Primarily no...
Scorpions are relatively large among terrestrial arthropods, with an average size of about 6 cm (2.5 inches). Scorpions exhibit few sexual differences, although males usually are more slender and have longer tails than females. Giants among scorpions include the black emperor scorpion (Pandinus imperator), an African species found in Guinea, which ...
In addition to desert habitats, scorpions have adapted to temperate, subtropical, and tropical environments such as grasslands, savannas, and forests. They live on all major landmasses except Greenland and Antarctica. Their range extends from Canada and central Europe to the southern tips of South America (Tierra del Fuego) and Africa, and they hav...
Breeding is seasonal and generally occurs during the warm months, ranging from late spring through early fall. Males may travel hundreds of metres to find receptive females. It appears that males find females by localizing a pheromone that the female emits from the end of her abdomen. Mating in scorpions is preceded by a complicated and characteristic courtship initiated by the male. He first faces and grasps the female, using his pincers (pedipalps). Then the pair, directed by the male, moves sideways and backward in a dancelike motion called promenade à deux. These actions result from the efforts of the pair to find a smooth surface on which the male can extrude a glandular secretion that forms a stalk to which the spermatophore (sperm-containing structure) is attached. He then maneuvers the female so that her genital opening contacts the spermatophore. Once she is positioned over the spermatophore, physical contact with it causes spermatozoa to be ejected into the genital opening (gonopore) of the female. Males that remain near females after mating are sometimes killed and eaten.

In general, females mate multiple times. In some species, mating must occur after each clutch of offspring is produced in order to fertilize another clutch of eggs. In others, multiple clutches of offspring can be produced from the sperm stored from a single mating. There are at least two species known that can produce offspring without mating at all (parthenogenesis).
The mother invests a great amount of time and energy in her offspring. Unlike most nonmammalian animals, scorpions are viviparous, giving birth to live young instead of laying eggs. Once fertilized, the eggs are retained in the female’s body, where the embryos are nourished in utero for periods varying from several months to a year. The birth process itself may last from several hours to several days. Temperate species usually give birth in spring and summer, whereas tropical species give birth throughout the year. Litter size averages 25, with a range of 1 to more than 100.

Scorpions are opportunistic predators that eat any small animal they can capture. Common prey includes insects as well as spiders and other arachnids, including other scorpions. Less-common but regular prey includes pill bugs, snails, and small vertebrates such as lizards, snakes, and rodents. The only known specialist scorpion is the Australian spiral burrow, or spider-hunting, scorpion (Isometroides vescus), which feeds solely on burrowing spiders.
Most scorpions are sit-and-wait predators that remain motionless until a suitable victim has moved into an ambush zone. Scorpions can sense tiny ground vibrations, and some can detect airborne vibrations of flying insects. These behaviours are sophisticated to the extent that scorpions can determine the precise distance and direction of their prey. Once the prey has been detected, the scorpion turns, runs to the prey, and seizes it. The prey is stung if it is relatively large, aggressive, or active. Otherwise it is simply held by the pedipalps as it is eaten. Many of the thick-tailed scorpions (family Buthidae), however, actively search for prey. These species usually have long, slender bodies and pincers (chelae). Many have powerful venoms to compensate for their small pincers.

- Despite their appearance, scorpions are not insects. Scorpions are arachnids, a group of invertebrate animals that includes spiders, ticks, and mites.
- Their name means ‘to cut’ or ‘sheer’ The word scorpion is derived from the Latin scorpio, which comes from the Greek word ‘skorpíos’, which means to cut.
- They are ancient creatures that have been around since the dinosaurs. Based on fossils and dating records, scorpions have been roaming the planet for hundreds of millions of years.
- Few are deadly enough to kill a human. Although there have been almost 2,500 species of scorpions discovered, only around 25 have venom lethal enough to kill an adult human.

Nov 21, 2023 · Male scorpions seek out pheromonal scents of a female scorpion. Once the male finds the female, he clasps the female's pedipalps and leads her in a dance called the promenade à deux .
To convey their interest in a female scorpion, males employ chemical attractants called pheromones. They also give off focused bodily vibrations. When a female is found, the male uses his pedipalps (the scorpion legs that look like claws or pincers) to grab onto the female’s pedipalps.
