The Giant House Spider

The biggest spider in London is the Giant House Spider (Eratigena atrica), also known as the Common House Spider or Greater European House Spider. This spider can grow up to 12 centimeters in length, including its legs, making it one of the largest spiders found in the UK.

Appearance

The Giant House Spider has a brownish-yellow body with darker brown stripes on its legs. Its body is covered in fine hair, giving it a fuzzy appearance. The males are typically smaller than females but have longer legs.

Habitat

As their name suggests, these spiders are commonly found inside houses and buildings. They usually build their webs in corners or dark places such as basements or attics. The Giant House Spider prefers moist environments and is often found near water sources such as sinks and bathtubs.

Behavior

Giant House Spiders are not aggressive towards humans and prefer to hide rather than confront them. They are nocturnal creatures that hunt for prey at night and remain hidden during the day. These spiders are known for their speed and agility, which makes them excellent hunters.

Mating

During mating season, male Giant House Spiders will leave their hiding spots to search for females. Once they have found a mate, they will approach her cautiously and use their long forelegs to hold her while they mate.

Conclusion

The Giant House Spider may be the biggest spider in London, but it poses no threat to humans. These spiders play an important role in controlling other insect populations and are an essential part of London’s ecosystem.

So, the next time you spot a Giant House Spider in your home, don’t be afraid. Instead, appreciate its beauty and let it continue its important work.
