Mediterranean recluse spider

Mediterranean recluse spider

Loxosceles rufescens

A species of Recluse spiders

Like other species of the genus Loxosceles, bites from the Mediterranean recluse spider can have dangerous effects, causing skin lesions – a condition known as loxoscelism. Despite co-occurrence with humans for millennia, there is only a single report of a human fatality linked to a bite from this species, a case report from 2016 in which no spider was captured for a confirmed identification, and in which the victim suffered from an autoimmune disorder (myasthenia gravis).

Bite Humans

Toxic to Humans

Mediterranean recluse spider possesses venomous fangs that deliver cytotoxins and proteolytic enzymes, inflicting toxic effects on humans ranging from mild to severe. Bites can lead to necrosis, systemic symptoms, or rare complications. Preying involves immobilizing with venom which, defensively, can result in accidental envenomation upon human contact.

Rectangle
Toxic to Animals

Mediterranean recluse spider is known to possess a defense mechanism that deters predators through causing discomfort upon contact. This organism secrets a toxin which, although mild in intensity, can affect both humans and a variety of animals. During both its larval and adult stages, mediterranean recluse spider does not actively leak venom but can cause mild poisoning when touched. For example, humans may experience skin irritation, while domestic animals like dogs and cats might show signs of distress. Birds and other insects could also be repelled or suffer adverse reactions if they come into contact with mediterranean recluse spider.

Rectangle
Bite Humans

Mediterranean recluse spider bites humans typically in self-defense when pressured against skin, resulting in localized necrosis. The spider injects venom through hollow fangs, with bites often occurring incidentally due to its inconspicuous nature rather than aggression.
