The brown recluse spider gets its name from its drab brown coloring and its habit of living a solitary existence. These spiders are characterized by a violin-shaped marking on the back of the neck. While many spiders have eight eyes, the Brown recluse has six eyes organized into three "dyads." Brown recluse spiders are small spiders rarely exceeding 3/8 of an inch in length. 


These spiders are most common in the southern plains states of Kansas, Missouri, Oklahoma, Arkansas, Texas, Louisiana and Alabama. They are also established in Illinois, Indiana, Ohio, Kentucky, and Tennessee. This spider loves dark places and is normally found under porches, in log piles, old tires, or in drains. Inside the house, brown recluse spiders may be found in dark basements, closets, or in trash cans. 


Brown recluse spiders will bite humans when threatened, although their bite is only powerful enough to puncture skin; it cannot bite through clothing. Although different people will experience a wide range of intensity of symptoms (some will experience little pain or minor symptoms while other experience intense pain and symptoms), a brown recluse spider bite normally requires medical attention, although there is currently no anti-venom for a bite from this spider. Some individuals (about 10% of those who are bitten) experience major tissue damage, necrosis (decay of skin and tissue) and infection as a result of a bite from this spider. In rare cases, individuals require the amputation of the affected limb.   ________________


The black widow spider is characterized by its black body and legs, and tell-tale red hourglass marking on the underside of its abdomen. Females can grow to lengths of about 1.5 inches. Males are smaller but have longer legs.


The black widow spider is one of the most feared spiders in the world. Its venom is extremely poisonous and is said to be at least 15 times more poisonous than the venom of a rattlesnake. Black widow spiders are found in many parts of the world, but in the United States are limited to the warmer climates of the southern and western portions of the county. Black widow spiders are fond of dark places such as under rocks or logs. In houses and buildings, they may take up residence in closets, furniture, pipes, or in basements. After a female and a male mate, the female often kills and eats the male, hence the name black "widow."


Black widow spiders eat other insects that they catch in their webs. Unlucky victims are injected with venom which liquefies their insides. The spider can then easily consume its prey. Black widow spiders will bite humans when they feel threatened. While the venom is not toxic enough to normally cause death, it is extremely painful, and is often severe enough to require hospitalization. Headaches, chest or abdominal pain, muscle cramps, and trouble breathing are the most common symptoms.
