Passage2: Brown window spiders

This type of spiders prefer to live in undisturbed areas, such as rock or woodpiles,  occupy garages, storage sheds, or crawlspaces, particularly in temperate regions around  the world. Black widows can be identified by their round, shiny black bodies and the distinctive red hourglass marking on their underside. Black window bites are rarely fatal, but can be serious and should receive medical attention as soon as possible. Symptoms may include headache, muscle cramps and weakness. Female black widow spiders are about 0.5 inch long, to about 1.5 inches long when the legs are spread. Males are about half the female's size, with smaller bodies and longer legs.Both females and males have shiny, globular abdomens and are mostly black and sometimes brown. Like many spiders, the black widow spider eats other arachnids and insects that get caught in their webs.
