Argiope bruennichi is found in long grass where it builds its web at ground level. A major component of its prey appears to be orthoptera. Eggs are laid in the autumn and protected by a large cocoon which resembles the fruit capsule of "Love-in-a-mist" (Nigella damascena). The eggs or young over-winter in the cocoon, to disperse in the spring. It is likely that this spider is now more widespread and under-recorded in the south of the county.
