Understanding Brown Recluse Spiders
What do brown recluse spiders look like?
The most telltale characteristic of brown recluse spiders is the presence of a dark, violin-shaped mark on the dorsum of the arachnid's light brown or yellowish-brown cephalothorax. The neck of this distinct violin pattern is directed toward the abdomen. Due to this marking, brown recluses are also commonly known as fiddle-back spiders. Baby brown recluse spiders do not have this distinctive marking. It develops as the spiders grow into adulthood. To positively identify a spider as a recluse, both the eyes and fiddle marking must be seen, since other spiders may possess one or the other characteristic alone.
Due to misinformation and fright, many people identify harmless spiders as brown recluses. They are also referred to as fiddleback spiders due to a distinctive marking on the thorax, which resembles a violin. Brown recluses have uniformly colored legs and abdomens, so any spider exhibiting distinct color variations and patterning on the legs or abdomen is not a brown recluse.
Where do brown recluse spiders live?
Brown recluse spiders dwell in many of the same dark, sheltered places as black widow spiders. They can be found in homes, barns, and basements. Brown recluse spider webs tend to appear disorganized and are built most commonly near ground level beneath rocks and logs. The spider is a hunter, so the web is not intended to catch prey but instead roams around searching for prey. The brown recluse is found in the central southern part of the U.S., from Texas to the westernmost part of Florida.
Although urban myth purports that they are found throughout the U.S., studies have shown otherwise. Brown recluse spiders are endemic only to the American South and Midwest. Relocation of the brown recluse can occur in boxes or items moved from its native range. These usually are isolated events and do not result in an entire area becoming infested.
Brown Recluse Mating & Lifespan Facts
Brown recluse spider mating occurs from February to October and results in 40 to 50 eggs that are deposited in off-white, round silken cases. The average lifespan of a brown recluse spider averages from one to two years.
Brown Recluse Spider Bites
Brown recluse spiders are shy and rarely bite unless provoked. Bites usually go unnoticed until effects manifest a few hours later. Most bites become red and fade away, but in uncommon cases, necrosis or tissue damage can occur. A medical professional should be consulted if there are medical concerns.
Many conditions are mistakenly diagnosed as brown recluse spider bites, including
Lyme disease, diabetic ulcers, reactions to medication, and bacterial infections.
