Figure 5 Brown recluse specimen. Note the distinguishing features of L reclusa: 6 eyes in 3 pairs of 2, and the finely haired exoskeleton without course bristles. Coloration is rusty brown, and many specimens feature a darker stripe along the abdomen. The classic violin-shaped marking is not always apparent. Photograph by Matt Britt, 2008, public domain.
