Hasarius adansoni
species of arachnid

Hasarius adansoni, known commonly as Adanson's house jumper, is a species of jumping spider that is common in warm regions around the world, often associated with people.
Distribution
H. adansoni is found in warmer climates around the world, for example Malta, India, Japan, Brazil, Taiwan, Tanzania, and Australia. It has also been introduced worldwide in greenhouses and similar places, for example in several German zoos. In China it is distributed in the provinces of Gansu, Guangxi, Guangdong and Yunnan.
Behavior
These spiders build a silken retreat at night, which is about twice the length of the animal. Although the same retreat is sometimes reused, others are built in the vicinity.
Males have been seen to feed on immature females, although this may be by accident.
Description
Females grow up to 8 millimeters in length, males up to 6 millimeters.
The males are mostly black, with a red "mask" and pedipalps that are partly white. A white crescent is present on the back part of the abdomen, and another one on the front part of the opisthosoma.

Why this record matters
“Hasarius adansoni” is worth following because a concise public description often conceals a longer documentary argument. Here, Hasarius, adansoni and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Feb 14, 2026. The linked authority identifier is Q1058728. None of the 0 selected statements returned an explicit reference.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
