Wasp Spider


Found on heathland in Dorset in summer 2013, the Wasp Spider. It's a very large, colourful spider that is a recent arrival in the UK from the continent and has slowly spread over the south of England. They build large orb webs in grassland and heathland, and attach their 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.
