Which marking is commonly described on the brown recluse spider?

• A. A brown crescent-shaped mark on the abdomen
• B. A blue hourglass marking on the thorax
• C. A brown violin-shaped marking on the body
• D. A yellow stripe along the legs

Answer: (C)

The main idea here is a distinctive body pattern used to identify the brown recluse: a brown violin-shaped mark on the dorsal surface of the cephalothorax, with the neck of the violin pointing toward the abdomen. This marking is the classic description people use to recognize the species, making it the best choice among the options.

The other options don’t fit because the violin-shaped marking on the cephalothorax is what’s traditionally associated with the brown recluse. The hourglass shape is linked to black widows (and is usually on the underside of the abdomen, not the thorax), a crescent on the abdomen isn’t the characteristic description for this spider, and a yellow stripe along the legs isn’t the identifying feature of the brown recluse.
