Buy Latrodectus tredecimguttatus Spider Venom
Latrodectus tredecimguttatus, also known as the Mediterranean black widow, or the European black widow, is a species in the genus Latrodectus of the widow spiders. It is commonly found throughout the Mediterranean region, ranging from southern Iberia to southwest and central Asia, hence the name. Specimens from central Asia are also known by the binomial name Latrodectus lugubris; that name, however, is now considered improper, though it is still commonly found in the literature. Latrodectus tredecimguttatus was previously considered a subspecies of Latrodectus mactans.
Like all Latrodectus species, L. tredecimguttatus has a painful bite that is fatal in rare cases. They are not in close association with humans generally, although epidemics of bites have been reported. There are many reports of Ukrainian farm workers receiving bites while working in the fields. The LD-50 of L. tredecimguttatus venom has been measured as 0.59 mg/kg, and separately again as 0.59 mg/kg (with a confidence interval of 0.33–1.06).
In Kazakhstan – where it has the common name karakurt (= black insect) – there are reports of this species biting and killing camels
