Brown recluse spiders (loxosceles reclusa) are part of the loxosceles species of spiders in the United States of which there are 13 different species, 11 native and two nonnative. The brown recluse spider is the most common spider linked to brown spider bites. These bites were originally reported in the US in the 1800s and are still reported today. These bites are so prevalent and serious that the brown recluse spiders are thought to be a clinical concern .
Normally, these bites happen without any notice since they usually occur without any pain . If an individual does feel something at the instance of a bite it is usually described as a similar feeling to a bee sting. When this spider bite happens, it causes skin and tissue injury in the affected area due to the venom of the spider. This localized or generalized symptoms following a bite are called loxocelism.
