Brown recluse spider. In this third post on spiders (previous ones on the tarantula and black widow spider here), we’ll talk about the brown recluse spider. Like the black widow spider, the brown recluse spider also has a unique marking on its body. It’s a tan spider with a violin-shaped marking on its [...]
With a bold bright red hourglass on its belly against a shiny black background, the black widow spider is all business. Thus, when the black widow spider attacks… well, you better hope it doesn’t!
