Wolf spiders are often seen in large numbers as was the case when this picture was taken, they could be seen everywhere running across the leaf litter and deadwood in a ditch. Female wolf spiders are 5.5-8mm and males are 5-6.5mm. They are mottled brown. They can be seen from March to July and feed on flies and other small insects. They can be seen scurrying around hunting for prey and warming themselves in the sunshine on patches of wood or soil. They do not use a web but catch their prey by running it down. After mating the female constructs an egg sac that is attached to her spinnerets at the tip of her abdomen. Because the egg sac is not carried in her jaws it does not affect her hunting. When the spiderlings hatch they climb onto her back. She discards the remains of the egg sac and continues hunting whilst carrying her babies for about a week. Picture taken at Old Warden Woods, Bedfordshire on 29th May 2012.
