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

땅에서, 대략적인 추측

뭘 먹을까?

It eats both insects and other spiders, woodlice, and small vertebrates such as pipistrelle bats and a pygmy shrew. It catches prey with an 'attack wrap', wrapping silk around the victim while it bites, and its venom quickly paralyses the prey.1

자주 헷갈리는 동물: It is often mistaken for the black widow (Latrodectus) and other false widow species. It can be told apart from the black widow by its larger size within its genus and its typical colouring, though many spiders in this group look similar.1

독의 힘

물어

물 때 독니나 이빨로 독이 나와.

이 독(물거나 쏘는 독)은 어떤 작용을 할까?

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

사실

The spider often catches prey much larger than itself, including bats, because its venom works quickly.1

It can survive without drinking water, getting all its liquid from its prey.1

Males court females by tapping the web and vibrating their bodies, and they can make scraping sounds with their abdomens.1

It has poor eyesight and relies mainly on vibrations travelling through its web.1

It produces three-dimensional cobwebs, and its silk is unusually strong for its genus.1

One adult female lived almost five and a half years in captivity, and adult females are long-lived.1
