How to breed book scorpions?
Breeding the book scorpion is basically simple. To breed book scorpions, you need to get familiar with the natural habitat of the pseudoscorpion. Book scorpions prefer dry regions around animals with a parasite plague. Hives are very suitable for them, provided that the bees do not receive acid treatment and attention is paid to heat-insulating dry hives. Hay and straw floors and grain stores near animal barns or hives with similar conditions are also optimal bases for reproduction and breeding of book scorpions.
Of course, book scorpions multiply very well in breeding boxes. A container of about 5 liters with a very tight lid, is the requirement for 10-30 book scorpions. A 5cm layer of wood chips then dry wood with many small cracks, form the living space of the book scorpion. Now the temperature must be only about 18 to 25°C and enough food in the form of small fruit flies, silver fish, springtails, beetle larvae, wood lice etc. must be available. Feeding should be added every 14 days. Darkness, dryness and temperature are the important points in breeding.
Pseudoscorpions communicate by pheromones and sign language. Same-sex book scorpions “wave” their claw arms or grab each other’s claw. This is because book scorpions each occupy small territories, which they defend against same-sex conspecifics. The territories have a rather circular size with 2-3 cm diameter and are marked with pheromones. When a female enters the territory of a male book scorpion, the males perform a mating dance. If the female stays within the territory, the male moves his body and vibrates. Both book scorpions then dance back and forth without touching each other. After a short time, the female stands directly in front of the male, whereupon the male book scorpion releases a spermatophore on the ground. Then the male grabs the arms of the female pseudoscorpion and helps her insert the spermatophore tip into the sexual opening. Ultimately, several thrusting movements by both animals follow before the female releases her grip and hurries away.
The female forms about 20-40 eggs from this and provides them with nutrient fluid in a brood pouch. When the brood pouch is large enough, nest building begins, which lasts for several days. For this purpose, the female carries small particles, such as sand, wood splinters and other plant materials, together and carefully spins them with silk.
The female book scorpions eventually hatch into the nest and completely seal it from the inside. The incubation period can last up to four weeks. About 5 embryos, called protonymphs, hatch from the numerous eggs. The other eggs die, as they succumb to the competition of development. Therefore, natural selection begins at a very early stage of development. There are three developmental stages in total, with protonymphs already hunting independently. Adult book scorpions can live up to four years.
