Adanson's house jumper
Adanson's house jumper hunts by sight rather than spinning a web, and courting males show a bright red face mask entirely absent in the plainer brown females.
| Where | Buildings, gardens and low vegetation |
|---|---|
| Size | Female 7 to 9.5 mm, male 4 to 7.6 mm body length |
| When | February to November |
Males are mostly black with a bright red mask on the face and white banded palps, while females are plain reddish brown; both sexes rely on excellent eyesight to stalk and pounce on prey rather than building a web to catch it.
It is diurnal, hunting by day and building a small silken retreat about twice its own length to shelter in overnight, often reusing the same retreat for several nights running.
