Physical Description and Identification

Adults

Size: These spiders have a length of about 7 to 12 mm (0.27 to 0.47 inches).

Color: Most species of the recluse family have a dark brown body, while the color ranges may vary from white, blackish gray or dark brown.

Other characteristics: Most of them possess six eyes arranged in groups of three. Certain spiders of this genus particularly the brown recluse have a violin marking on their cephalothorax.

Recluse Spider Size

Eggs

The eggs of the majority of the species belonging to this genus are contained in a silken sac that has an off-white color with the outer part woven loosely.

Spiderlings

The spiderlings closely resemble the adults, though they have a lighter body color.

The Web

Being hunting spiders, they do not need to catch their prey using webs. However, the webs woven by most of them have an irregular pattern, being constructed loosely.

Do Recluse Spiders Bite and Are They Poisonous

They are venomous and are known for inflicting grave bites, which could result in severe wounds and a host of symptoms referred to as loxoscelism. The female spiders are known to carry a bigger amount of toxins than their male counterparts. Having said this, most recluse species are non-aggressive, and the bites might result as a mode of self-defense when provoked or in an attempt to rescue themselves when trapped in the skin amidst clothing. The brown recluse is said to be the most dangerous of the genus and their bites could sometimes call for medical attention.
