Though the bite is extremely rare, it is responsible for a condition called loxoscelism. This is the only known cause of necrotic arachnidism tissue death from a spider.
The name comes from the Loxosceles genus, to which all recluse spiders belong. But how do you know if it really was a brown recluse that bit you? This is a very common question because there is a lot of anxiety and fear surrounding the brown recluse.
Capturing the spider responsible will help you identify it, but don't put yourself in danger of another bite to do so. Many of your fears can be put to rest with a little understanding of the brown recluse. For instance, these spiders only live in certain parts of the United States and death from a bite is very rare. Also, keep in mind that not all skin boils and necrotic dead tissues are caused by brown recluse bites or even spider bites , for that matter.
Recluse spiders are called recluse because they do not like to be seen. These nocturnal creatures will not attack people unless they're provoked. The majority of brown recluse bites occur because the spider ended up in the person's clothing.
With that knowledge, where you live is actually the first clue on whether or not you've been bitten by a brown recluse. This particular species is found only in the South-Central United States. In one study, researchers invited people to send them spider specimens they believed to be brown recluses. Out of a total of 1, arachnids submitted from 49 states, different species were identified.
From those 29 states where brown recluses are not common, only two brown recluse specimens were identified. This study found that if you get bitten outside of where brown recluse spiders are known to live, the chances that it came from a brown recluse are nearly zero. It is more likely that the injury was caused by any number of other things, possibly even another species of spider that is less venomous.
For instance, if you were bitten in northern California or Maine, there's almost no chance it's from a brown recluse unless you recently returned from Mississippi. You can rule out the brown recluse if you aren't in the areas where brown recluses are known to live. Assuming you're in the territory of the brown recluse, it is best if you were able to see the spider that bit you.
However, many people do not even realize when they are bitten, so sightings are rare. If you were, by chance, able to capture the spider that bit you, that is even better. Classifying it is difficult and only an arachnologist spider expert can accurately identify a brown recluse for you. It's probably beyond the expertise of your healthcare provider as well, though you should see him anyway if the bite worsens.
While you and your healthcare provider may not be able to identify the brown recluse, there are a few indicators that you have a spider that is at least in the recluse family.
If you can safely observe it, here's what to look for:. Brown recluses are also called violin spiders or fiddlebacks. These names refer to a violin-shaped mark on the spider's back. However, it's not always obvious on brown recluses and it shows up on other species as well.
Look for the other identifying information instead of relying on the violin. The problem is that it's more than likely you didn't even feel the bite.

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. Brown recluse spiders dwell in many of the same dark, sheltered places as black widows. They can be found in homes, barns and basements.
Webs tend to appear disorganized and are built most commonly near ground level. 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. 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. Although urban myth purports that they are found throughout the U. 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.
Many conditions are mistakenly diagnosed as brown recluse spider bites, including Lyme disease, diabetic ulcers, reactions to medication and bacterial infections. 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.
