Webs around holes in walls, where the spider lurks. The vibration from a tuning fork held to the web will bring its owner racing out.

Body length: up to 10mm. Restricted to houses; lurks in corners and traps house spiders by flinging silk at them. Open webs between wall and ceiling built by this lanky building-dweller. Spider trembles and gyrates if disturbed. Carries eggs in jaws.
