Brown Recluse Spider


The brown recluse spider, Loxosceles reclusa, is believed to have gotten to through accidental transport. The first recorded case was from a sailor who had picked up cargo in North Carolina. Although brown recluse spiders are not believed to have an established population in the state, hundreds of alleged brown recluse spider bites are reported every year.

Appearance of  Brown Recluse Spiders
Both males and female  brown recluse spiders are typically between a quarter and ¾-inch in body length, most averaging about 1/3-inch. They are mostly brown but can range in color from a light, cream-color to a dark brown almost grey color. They have short hairs on their backs that give the appearance of soft fur.  Brown recluse spiders' most common identifying mark on the dorsal side of their cephalothorax with a black line coming from it that looks like a violin. Because of this they are often referred to as the fiddle back or violin spider. Different from most spiders, brown recluse spiders have three sets of eyes (6 eyes in total).

Development of Brown Recluse Spiders
Typically from May to July, females prepare countless silken sacs filled with eggs over the course of two to three months. Spiderlings hatch from eggs and the spiderlings take about one month to hatch and about another 11 months to reach adulthood.  Brown recluse spiders typically live between one and two years.

Behavior of Brown Recluse Spiders
They tend to build their nests in generally undisturbed dry areas, for example in garages, woodpiles, sheds and closets. Inside buildings, they are most typically found dwelling around cardboard. Occasionally they have been found inside of dressers, shoes, socks, between bed sheets, inside gloves and other places of warmth and darkness. Unfortunately, they bite humans when they feel that their area is being threatened. Unlike most other species of spiders, Brown recluse leave the web at night to hunt. The brown recluse spider is a survivor, it can withstand up to 6 months with no water and scarce food.

The Brown Recluse Spider's Bite
Although brown recluse spiders are not characteristically aggressive, their bite can pose a serious threat to humans. Their fangs contain hemotoxic venom that can lead to problems. The majority of brown recluse spider bites are only identified after a victim goes to the doctor with Necrotic lesions. Other serious complications from brown recluse spider bites are hemolysis, thrombocytopenia, disseminated intravascular coagulation, organ damage, and even death. Most fatalities are children under the age of seven or those with a weaker-than-normal immune system.
