What is the typical length of a brown recluse spider?

The typical length of a brown recluse spider is about 3/4 inch long when measured from the front of the cephalothorax to the end of the abdomen. This measurement reflects the average size range for the species, making option D the most accurate response.

In general, the adult brown recluse spider's body can reach about 1 to 1.5 inches when legs are included, but the body alone is typically smaller. This species is often recognized by its violin-shaped marking on its back and its long, slender legs, which further contribute to its overall size perception. The other options either overstate or understate the average size, which is why they do not reflect the true measurement characteristic of the brown recluse spider.
