A building as habitat
Fine, irregular webs occupy sheltered corners in buildings. The long-legged spider may hang in them with its body facing downwards. A house provides spaces for more than people: other animals use its niches when conditions suit them.
Why the web seems to shake
When disturbed, the spider can vibrate rapidly in its web. This is observable behaviour, not a sign of bodily damage. Movement alone, however, cannot reliably identify every long-legged spider as this species.
More than a slender outline
It captures insects and other spiders, using silk to wrap them. Females carry their eggs at their mouthparts. These observations reveal hunting and reproduction on a small scale; our portrait nevertheless cannot replace an identification key.
