Brown recluse spiders also have a distinct marking. These spiders — which are typically found in the Midwest or South — have a “dark violin-shaped (or fiddle-shaped) marking on its head,” according to the CDC.
Brown recluse spiders are found in dry, sheltered areas, such as a under a log or rock. Inside homes, however, they typically hide in shoes, closets, attics or garages.
“The brown recluse spider cannot bite humans without some form of counter pressure, for example, through unintentional contact that traps the spider against the skin,” the CDC reported, adding that the bite marks typically appear as a “white blister” and can produce localized pain, a stinging sensation and lesions.
Fun fact: While most spiders have eight eyes, the brown recluse has six.
