This spider has six eyes arranged in sets of two, instead of eight eyes arranged in sets of four, like most spiders have. The brown recluse is active at night. It spins a sticky, unusual web with threads going in all directions. The brown recluse can live a long time with out food or water. You can find this spider under rocks, indoors under furniture, or in undisturbed areas.
Bites can occur when a human comes in contact with clothes that has been inhabited by the spider.
A couple of hours after the spider bites a person the skin around the bite gets red and swollen. The bite can lead to severe infection which can cause severe illness or even death. Originally the brown recluse was found in the south-western part of the United States. Today it is found in all parts of the country.
