The wasp spider is a very large, colourful spider that has recently arrived in the UK from the continent and has slowly spread over the south of England. It builds large orb webs in grassland and heathland, and attaches its silk egg-sacs to the grasses. The web has a wide, white zig-zag strip running down the middle, known as a ‘stabilimentum’, the function of which is unclear.
Mating is a dangerous game for males; they wait at the edge of the web until the female has moulted into a mature form, then take advantage of her jaws being soft and rush in to mate. However, many males still get eaten during this time.
