The noble false widow is a spider that looks a lot like the black widow, which is why it has its name. It is now found in many parts of the world, including Europe, the United States and New Zealand, and it is one of the world's most invasive spiders. Its bite can be painful, so it is worth knowing what it looks like.1

Most of its venom is made of toxins similar to those of the widow spiders, mainly alpha-latrotoxin. This toxin makes holes in nerve cells, which releases chemical messengers and blocks the signals between nerves and muscles, causing paralysis. In people, the venom is most noticeable as pain at the bite site, along with swelling, redness and fever.1

It is considered moderately medically significant. Most bites cause symptoms similar to a bee or wasp sting, but some can be more serious, partly because of bacteria. It is considered one of the most dangerous spiders in western Europe. Bites from males are less severe than bites from females, and the bite itself is usually painless, with pain coming from the venom.1
