Range
This spider ranges from New England south to Georgia and Alabama and west to Kansas and Minnesota.
Habitat
This species prefers warm and dry habitats. It can be found inside rolled leaves, on fences, under stones and boards, and will frequently enter houses by accident in the autumn
Life Cycle
Females will deposit a white egg sac containing about 30 to 50 eggs in September or October.
Remarks
Will not bite unless handled or provoked.
There are records of secondary infection associated with the bite, which may result from the spider's propensity for feeding on dead arthropods. Typically, the bite results in redness and some swelling, similar to a bee or wasp sting.
