Eratigena (House Spider)
The Giant House Spider (Eratigena atrica) is one of several similar looking species which inhabit houses and outbuildings - hence the common name "House Spiders".
These spiders make a thick sheet web, about 15cm across, usually in a neglected corner of a house or shed. The web has a tubular retreat at the rear where the spider sits and waits for dinner to drop by.
They become more noticeable in autumn, which is their mating season. The males are often seen scuttling across a room or falling into bath tubs as they move around in search of a female. The males have longer legs than the females, while the females have broader abdomens than the males.
The 'Aggressive House Spider' (Eratigena agrestis formerly Tegenaria agrestis), which has been made famous by a thousand Internet horror stories, belongs to the same Genus of spiders. Agrestis is rarely seen in houses, preferring sheds, garages, and log piles. In the United States, where it's known as the 'Hobo Spider', it has a reputation for biting humans with very little provocation. The ones found in Europe are quite timid in comparison, preferring to run for cover.
