The Adanson's house jumper (scientific name: Hasarius adansoni) is a type of jumping spider. These spiders are very common in warm parts of the world. You can often find them living near people.

Where They Live

Adanson's house jumpers are found in many warm places across the globe. This includes countries like India, Japan, Brazil, and Australia. They have also traveled to other parts of the world. Sometimes, they live in places like greenhouses or zoos, even in cooler climates.

What They Look Like

These spiders are quite small. Female Adanson's house jumpers can grow up to 8 millimeters long. Males are a bit smaller, reaching about 6 millimeters in length.

Male Spiders

Male spiders are mostly black. They have a cool red "mask" on their face. Their pedipalps (small leg-like parts near their mouth) are partly white. They also have white markings on their body. You might see a white crescent shape on their back. There are also a few small white dots near the end of their body. These white areas, especially on their pedipalps, can look shiny like a pearl.

Female Spiders

Female Adanson's house jumpers are dark brown. Their main body part (called the opisthosoma) is a lighter, reddish-brown color.

Behavior

These spiders are known for building a special silk "retreat" at night. This retreat is like a small sleeping bag, about twice the length of the spider. They sometimes reuse the same retreat. However, they might also build new ones close by.

Naming the Spider

This spider was first described in 1826 by a scientist named Audouin. It was named after a French naturalist, Michel Adanson.
