Spiders on Ice - NHPR

Wolf spiders do not build webs, but actively hunt their prey of small arthropods. Some live in burrows, while others are free ranging. The female carries the egg sac with her, attached with silk to her spinnerets. Once the spiderlings hatch they are carried around on her abdomen until able to look after themselves. Local pain and swelling have been reported after bites from this spider. One case of suspected necrotising arachnidism was circumstantially associated with a wolf spider, but good evidence for their involvement in this condition is lacking.
