Adult brown recluse spiders are about the size of a quarter, including their bodies and legs. They have long, thin legs and bodies that are usually light to dark brown colored. Similarly, male southern house spiders are also light brown with long, thin legs. In addition, both kinds of spiders usually prey on household pests, such as flies and other insects. Southern house spiders also build disorganized-looking webs, but they use theirs to trap prey. This means that you will typically find insects or insect parts in their web.

The southern house spider was described in the genus Filistata, but was later placed in the genus Kukulcania (Lehtinen 1967). This common house guest is typically dark brown or orangish-brown in color and has stripes on its legs. They can be found in dark, quiet spaces like cabinets and undisturbed rooms like attics, basements, and garages. Identifying common house spiders is a great way to ensure you handle them correctly.

In some parts of its distribution area, the arachnid is also known as the southern crevice spider.

These spiders are generally found within their distinctive tangled web. During the day, they generally hide in the crevice from which the web emerges, but at night, they will come out and sit on the web. The webs have a decidedly unkempt appearance with debris and body parts of insect prey they have devoured. The brown recluse spider, as seen above, is one of the few spiders in the United States that can pose a serious risk to humans. These spiders are sometimes referred to as fiddleback or violin spiders.

Males do not build webs but instead wander in search of females in order to mate. Females lay about 200 eggs that are loosely swathed in a silken ball about 15 mm in diameter and are kept with the female in her nest. In Florida, all stages of development seem to be present throughout the year.
