Southern House Spider

• The old webs of this species, coated in dust, are the classic grey cobweb of the corners and porches of the American South.
• Its silk is not sticky: it combs it with an organ called the calamistrum into an extremely fine wool that tangles insects' legs.
• It is long-lived for its size: the females can spend several years in the same crevice.
• The two sexes look like different species: the female is stout, black and velvety, the male slender, light brown and long-legged.
• That brown male is constantly mistaken for the brown recluse, which causes unfounded alarm and needless spraying. The reliable way to identify it is the web: coarse tangles in corners and crevices.
• It is harmless: it bites reluctantly and its venom is of no medical significance.
• Its silk is cribellate, with no droplets of glue.
• The females are long-lived and can spend several years in the same hiding place.
