  • Buthus occitanus berberensis Pocock, 1900 : Eritrea, Ethiopia.

The Breeding

Note: One of the common species very visible in France with Euscorpius. But it is also found, all around the Mediterranean basin, as well in Israel, as in Turkey, Sicily, North Africa and even Senegal in Somalia. Obviously, within sight of occupied surface, the differences in aspect are very numerous, as well cuts some as color.

Temperature:

Temperature until 35°C for the species living in north Africa, with 25°C for the European ones, minima for the winter: 10°C. A night fall from at least 7 with 8°C is always required. The winter a diapause is necessary if you want to have a reproduction and to prolong the life expectancy of your specimens. It is then necessary to reduce the temperature (11°C) and to decrease the contribution in food. Into summer, its behavior changes with the increase in the temperature, more it makes hot plus this one becomes aggressive.

Food:

Especially crickets, but some small spiders as well as the small cockroaches are accepted in general. Eat also other scorpions, same species or of another of lower size. In nature, any insect which passes close to its grips is a potential prey and very often one finds it under the stones with the quite round belly. It pricks with all the blows its prey.

Terrarium:

Of share its geographical distribution, this species does not have a particular habitat! One finds it in mountainous areas in Morocco, in arid mediums as in Tunisia like in places moderated as in the south of France. According to the source, the terrarium could be of moderate type (for the European subspecies) to steppe seeing even desert. However generally a mixture of argillaceous ground or sand is appropriate to him perfectly. On a hard ground this species will dig a hiding place. For the hygroscopy count 35% the summer and 60% the winter, but do not forget to provide him to drink. Not too much not to vaporize in terrarium, especially for the old specimens coming from the dry areas. Indeed, of the mycoses can cause the death of the scorpions. Stones or barks are the welcomes to be used to him as hiding-place. For a specimen, a terrarium of 10x20 is enough, for a minimum couple or more 30x20.

Sociability:

It is not, itself, a sociable species. It sometimes happens of the times to find two scorpions together under the same stone, but when you put them together in a terrarium, largest eats smallest. However, it is possible to put a couple together, but supervise the first contacts well then, if all occurs well, supervise during a few days if very continuous to occur well. In the event of birth, isolate the mother and the small ones. Those Ci, after their first moult will be insulated in their turn. The gestation period can last from 10 to 11 months, the range can give 70 small pullus, but count a little less. The mortality of the young people is very significant at the time of the moults.

Note:

The subspecies tunetanus is potentially dangerous for the man.
