What is the Deal with Spiders?

I have had a bunch of people (upwards of 50) hit my blog within the past few days, looking for pictures of black widows and brown recluses. They come from all over the place. What's that about? Is there some kind of game or scavenger hunt or something? Really, I'm curious so if you stop by my blog looking for them let me know why. There has also been a rise in the number of people looking for St. Louis Cardinals logos. Can't explain that either.
