The Mediterranean black widow is a member of the family of comb-footed spiders. Italian entomologist Pietro Rossi first described this species in 1790. This species was at one point considered a subspecies of the southern black widow.
Mediterranean Black Widow Spider
Size: Male: 0.4-0.7 cm Female: 0.7-1.5 cm
Color: They are black, with thirteen spots on their dorsal abdomen. These spots are red but sometimes yellow or orange in some individuals.
Other Characteristic Features: Their abdomen is covered in long and short hairs.
Latrodectus tredecimguttatus
They lay their eggs in a giant white sac, producing 6-8 sacs in their lifetime.
Hundreds of spiderlings emerge from the sac laid by their mother.
Their webs consist of three layers, with the middle layer shaped like a series of hexagonal meshes.
Only the females are considered deadly, as the males lack strong mouthparts to pierce human skin. Their bite is painful but only fatal in rare cases.
