Distribution and habitat

The distribution range of the mainly crepuscular and nocturnal Black Laos Scorpions extends over large parts of Southeast Asia. They prefer to inhabit dense rainforests, where they live in self-dug or natural burrows under stones or branches and pieces of bark lying on the ground.

Maintenance

For 1 animal a terrarium of L 40 x W 30 x H 30 cm can be recommended. For a pair or group keeping the terrarium must be extended accordingly. The terrarium should be placed in a quiet and vibration-free place without direct sunlight.

The terrarium should be structured with stones, cork tubes, pieces of bark, roots and branches (hiding places). They need a small, shallow drinking bowl with gravel and a 10-15 cm deep substrate of sand-loam-peat mixture suitable for digging. The substrate should always be kept slightly moist. Waterlogging and mold must be avoided at all costs. Artificial or potted plants (e.g. Ficus repens, Scindapsus aureus) can be used for decoration. Once a day the inside of the terrarium should be finely sprayed with water (humidity), but a rain or mist system is better.

Temp. day: 25-30 °C

Temp. night: 20-22 °C

Humidity: 60-80

The lighting duration should be 10-12 hrs. depending on the season. A conventional light source (fluorescent tube, incandescent bulb) is sufficient. Attention should be paid to their natural day-night rhythm.

Diet

The diet consists of crickets, cockroaches, house crickets, maggots and grasshoppers as well as other arthropods. Wax moths should only be fed in small quantities to adults, but not to juveniles, because of their large fat content

Using fruit and honey water as food for the foragers can enhance their quality. It is important to add minerals and vitamins regularly (dusting the feed animals). Young animals should be offered food daily, adults 1-2 times a week. Feeding should be done only in the evening. Hungry scorpions keep their pedipalpal claws wide open and actively search for food. Drinking water must always be available

A varied diet promotes health and prevents deficiency symptoms.

Reproduction and breeding

The sex difference is difficult to see. The sexual opening is heart-shaped in the female and oval in the male.

The mating ritual resembles a wrestling match and is often misunderstood as aggressive behavior. During this "mating dance" a sperm package (spermatophore) is passed. Females can also give birth to offspring several times without further mating (sperm storage). After a gestation period of 12-15 months, the female gives birth to up to 30 young. The white, barely mobile young find protection from predators on the back of the mother for at least 2 weeks, until after the 2nd molt. Only then do they begin to feed independently. The young can be raised together if there is sufficient food and plenty of hiding places.

Obligation to report

Make sure to inform yourself about any regulations on keeping or bans on keeping this animal in your state or home municipality (e.g. public order office). Your pet store will be happy to provide you with further information.

Important

Care should be taken when handling them in the terrarium. They are hardly aggressive and only weakly poisonous, the poisonous effect is similar to that of a bee sting. However, the sting itself can cause severe pain. For relocation, the animals are grasped with approx. 30 cm long feeding tweezers at the rear end and not at the front body (risk of injury)

Good ventilation without drafts is necessary, as well as equipment for measuring temperature and humidity. Lighting should be placed in such a way that the animals cannot injure themselves. The terrarium should be locked in such a way that neither unauthorized persons can open it nor the animals can escape. Special attention should be paid to thorough hygiene and impurities must be removed regularly.
