እንታይ ይበልዕ?

It eats a variety of insects, and also woodlice, millipedes, centipedes and other spiders. When prey is caught in its web, it rushes out, wraps the prey tightly in silk, and bites it. It then releases digestive enzymes into the wound and carries the prey back to its retreat to feed.1

ሓቅታት

In 1933, Allan Blair let himself be bitten by one of these spiders to study its venom in humans and to convince sceptics that it could be dangerous.1

Females will occasionally eat their mates after reproduction.1

Only mature females can bite people. Their hollow, needle-like mouthparts are about 1 mm long, which is long enough to inject venom into people.1

The brown widow (Latrodectus geometricus) competes with black widows for territory. In areas where they share space, it can displace them.1

Males live only about three to four months, while females can live for up to three years.1
