Brown Recluse Spiders

Brown recluse spiders, as their name implies, are a species that likes to be hidden. Brown recluse spiders are distinguished by a distinctive, dark, violin-shaped marking on the dorsum. This is usually found in the cephalothorax which is either yellowish-brown or light brown. This distinctive violin pattern is directed towards the abdomen by the neck. Brown recluses are often known as fiddleback spiders because of this marking. This marking is most prominent on older spiders.

Brown recluse spiders are able to see six eyes instead of the usual eight.

Habitat & Behavior

Brown recluse spiders live in the same dark, protected places as black widows. They can be found in basements, barns, and homes. They are often found near ground level and appear disorganized. Because the spider is a hunter and not a trapper, webs are often built near ground level. The central part of the United States that houses the brown recluse can be found is the southernmost part of Texas, Florida and Texas.


Brown recluse spiders are timid and will not bite unless provoked. Bite are usually not noticed until the effects start to manifest several hours later. Although most bites are temporary and disappear, in rare cases necrosis or tissue injury can occur. If you have any medical concerns, you should consult a medical professional.

The Brown Recluse Web

Here are some characteristics of a brown recluse spider web:

  1. Irregular Webs:Brown recluse spiders build irregular, messy webs that serve as retreats rather than for capturing prey. These webs are not used for hunting like the orb webs of some other spiders.
  2. Retreats:The web of a brown recluse is more of a retreat or hiding place than a traditional web for catching insects. They may build their retreats in dark, secluded areas, such as closets, attics, basements, or behind furniture.
  3. Silken Retreats:The retreat is typically a silken structure with a small opening for the spider to enter and exit. It provides a secure hiding place where the spider can rest during the day and emerge to hunt at night.
  4. No Sticky Silk:Unlike many other spiders, brown recluse spiders do not use sticky silk in their webs to capture prey. Instead, they actively hunt for small insects and other arthropods.
  5. Hunting Behavior:Brown recluse spiders are nocturnal hunters, meaning they are more active during the night. They use their silk to create a retreat where they rest during the day and venture out at night to search for prey.

These are usually isolated events that do not infest an entire area.
