Tegenaria saeva is very common in Cornwall in the corners of rooms in houses and outbuildings where it spins a large sheet web. Males are often found wandering in search of females in the Autumn when they cause alarm by running across carpets, and getting trapped in the bath (they do NOT crawl up the plughole!). However, the species can also be found away from houses in sheltered areas under rocks and in similar habitats.
     There has been some confusion regarding which species of Tegenaria definitely occur here. All the specimens of Tegenaria 'gigantea' and Tegenaria 'atrica' I have checked from Cornwall were Tegenaria saeva. Tegenaria saeva has a pronounced westerly bias to its distribution in Britain and is likely to be present in every house in Cornwall.
