I know many of you don't like spiders but if you can get past your squeamishness just for a minute and watch this video you will be amazed at how the spider catches it's prey. And remember these spiders are helping to control cricket, grasshopper, and other insect populations around your home.
Trapdoor spiders have been known to live for up to twenty years. If you watch the video you can see how efficient a trapdoor spider is at capturing prey. The spider waits till the cricket is just past the trap door and in one quick movement he opens the door, captures the cricket, and retreats back in the den with the trapdoor falling back in place. The spider isn't exposed to any predators for more than a second or two. No wonder they live so long.
