Euscorpius flavicaudis
(DeGeer, 1778)

 

 

 

Common names:
All Euscorpius were previously placed in the family Chactidae.

Distribution:
Africa (Algeria, Tunisia), Europe (France, Italy, Spain). Introduced to Great Britain and Uruguay (South America).

Habitat:
Warm, temperate climate in South-Western Europe. It is found in different habitats (in gardens, under stones, in houses, in old walls).
The species in not uncommon in human habitations. In Great Britain, the scorpion occupies cracks and holes in walls where the mortar pointing has crumbled away. Data on natural habitats in Southern Europe wanted!

Venom:
Few medical data available, but data from Italy suggest local effects only. Mildly venomous. Harmless scorpion, which rarely will use its stinger. According to Dr. Tim Benton, the sting is less than a pin-prick to humans.

General:
This species is a small black scorpion with yellow-brown legs and sting (telson). Adults measure 35-45 mm. It is a typical fossorial scorpion with large, strong pedipalps, a stout body, short legs and a short, thin tail (metasoma). See the Euscorpius identification key for more details.

This species is kept in captivity (especially in Europe), but not as coomon as should be espected from a "native" scorpion. Few commersial suppliers deliver this species (and other Euscorpius).
