It is a rather small pale yellow spider, found in most of North, Central and South America. It takes shelter in flattened silk tubes during the day and move about to hunt during the night. It often lives in houses. The bite of these spiders is toxic to humans but rarely produce more than local symptoms. They are believed to produce a high percentage of the spider bites suffered by people, probably because they wander about when people cannot see well or are asleep, and so they may get squeezed and bite to protect themselves.
