What is a key characteristic to identify the brown recluse spider?

The key characteristic to identify the brown recluse spider is indeed the violin-shaped pattern on the cephalothorax, which is a distinctive feature of this species. Additionally, brown recluse spiders have six eyes arranged in pairs, rather than the typical eight found in most spiders. This unique eye arrangement is significant in distinguishing them from other similar-looking spiders.

The presence of the violin shape on the cephalothorax is an important identifying feature, as it serves as a visual marker when encountering this spider. This shape, along with the specific eyes count, helps in proper identification during pest management practices.

While the other options contain elements that relate to spider identification, they do not accurately reflect the characteristics of the brown recluse. Understanding these traits is crucial for anyone involved in pest control or public education about potential spider encounters.
