The European garden spider is a large orb-weaver that spins round webs. It is native to Europe and was introduced to North America. Its white markings form a clear cross on its back, which is why it is easy to spot in the right place.1

Imbaraga z'ubumara

Iraruma

Ubumara busohokera mu menyo yayo y'ubumara cyangwa mu yandi menyo iyo iriye.

Ubumara bwayo bukora iki?

The bite paralyses prey, which keeps the spider safe from being stung or bitten in return. Enzymes in the venom start to liquefy the prey's internal structures.1

It is reclusive and only bites people when cornered or provoked.1

Ikora iki iyo ifite ubwoba?

When disturbed, it vibrates rapidly in its web until it becomes a blur, which is thought to confuse predators.1

Ibintu by'ukuri

1

Females sometimes eat the male directly after mating.1

2

The cross-shaped markings are formed in cells filled with guanine, a by-product of protein metabolism.1

3

Spiders also prey on each other, but only just before, during or after mating. Their size, mating experience and hunger affect whether they attack.1
