The spider builds a spiral orb web at dawn or dusk, commonly in long grass a little above ground level, taking it approximately an hour. The prominent zigzag shape called thestabilimentum, or web decoration, featured at the centre of the orb is of uncertain function, though it may be to attract insects.
A female quickly immobilises a grasshopper by wrapping it in silk. The prey is bitten and injected with dissolving enzymes.
When a prey item is first caught in the web, Argiope bruennichi will quickly immobilise its prey by wrapping it in silk. The prey is then bitten and then injected with a paralysing venom and a protein dissolving enzyme.
During Summer 2006, research was carried out in the UK to find that there has been an influx of these spiders to the UK. The colour is still similar, although the yellow stripes are a bit more cream coloured.
