Brown Recluse Spider

Dear Ryan,
The shape of this spider sure looks like the shape of the Brown Recluse Spider,
Loxosceles reclusa, and sure enough when we enlarged and lightened the image, we could make out the distinctive “violin” marking on the cephalothorax.  Here is a BugGuide image for comparison.  According to BugGuide:  “Caution: This spider is venomous and can harm people, though large numbers of BRS are sometimes found in close proximity to people w/o their getting bitten. (2The Brown Recluse is very shy and nocturnal, therefore most likely encountered at night when it is foraging for food. During the day the brown recluse hides in secluded places.  An interesting fact is the brown recluse cannot bite through clothing because of its small fangs.  Most brown recluse bites result in only a small red mark and heal without serious complications.  The bite of the brown recluse is usually painless and many go unnoticed for as long as 2 to 8 hours or the victim may feel a stinging sensation later followed by intense pain. A small white blister develops at the site of the bite, followed by swelling of the area. This swollen area enlarges and becomes red. The site becomes painful and hard to the touch. A necrotic lesion develops and the affected tissue dies and slowly sloughs away exposing the underling tissue. This necrotic ulcer may persist for several months and heals slowly, leaving a sunken area of scar tissue.   It is exceedingly hard for a physician to correctly diagnose a “brown recluse bite” based simply on the wound characteristics.  In very rare cases, the bite may result in a systemic reaction accompanied by fever, chills, dizziness, rash or vomiting.”

Thanks for the reply, that’s what I feared!
