Facts About Brown Spiders
When people think about poisonous brown spiders, the brown recluse spider comes to mind. The brown recluse has a back that is dark brown with a light brown body. These brown spiders bite, yet they choose to hide and stay away from humans.
Common kinds of harmless brown house spiders are more likely to be found at home. The cupboard spider, American house spider, basement spider, and aggressive house spider are just a few examples. Brown spiders are considered a nuisance pest rather than a threat, despite the fact that they bite. Brown spiders belong to the class Arachnida, which includes all eight-legged spiders. Spiders, on the other hand, aren’t insects, which is something to keep in mind.
How to Identify Brown Spiders
The body form, coloration, patterns, size of legs, and smoothness or hairyness of a brown spider can all be used to identify it. Also, the head and thorax (cephalothorax) of spiders are distinguishable from the abdomen. Spiders have eight legs, not six, which is another identification characteristic. Spiders don’t have antennae or wings, unlike insects. Spiders can also have up to twelve eyes, although the majority have four or eight.
The kind of webs spiders spin is another technique to identify them. Brown cellar spiders, for example, create tangled webs. Yet, certain spiders weave complex orb webs, which are unique to them and their kind. The habits and habitat of spiders are used to identify them.
Types of Brown Spiders (With Pictures) – Identification Guide
To learn how to identify scurrying eight-legged arthropods, let’s take a look at some common brown spiders.
Brown Recluse Spider (Loxosceles reclusa)
The brown recluse is a venomous spider with a bulbous, light brown oval abdomen and eight legs, as well as a furry appearance. Brown recluse spiders have a violin-shaped marking on the front section of their light brown bodies, which is their identifying feature. It’s also one of the few spiders with six eyes, which is unusual. Brown fiddler, fiddleback spider, and violin spider are some other names for the brown recluse spider. It’s also vital to keep in mind that other brown spiders have a violin-like pattern on their backs, too.
Brown recluse spiders range in size from 0.24 to 0.8 inches (6 to 20 mm). The venomous brown spider has spindly legs that stretch out in a star formation when compared to its body. Seal all gaps and openings in your home’s foundation to keep a brown recluse out. Brown recluses may also be prevented from entering your home by using bug screens and floor cleans. It’s also a good idea to empty attics, basements, and closets of all superfluous stuff.
Basements, cupboards, closets, attics, and boxes are all places where brown recluse spiders like to hide. As a result, to avoid brown recluse spider bites while transferring goods in these areas, use gloves. A brown recluse spider bite might cause pain, fever, localized redness, and swelling in the same way that a black widow spider bite does. If you suspect a brown recluse bite, seek medical attention right away.
