Is this a wolf or grass spider?

    I found this guy on my basement floor. What species is it? I think it's either a rabid wolf spider or a funnel web/grass spider. But I have no idea how to tell those apart! :eek:

    That's a wolf spider. If you take a look at the eye pattern you can see that 2 of the eyes are bigger and facing forward. And one more thing: grass spiders have bigger spinnerets.

    Definitely a wolf spider. That's all I can say. Like others have said, wolfies have those 4 big eyes on top of the head, and grass spiders have two(?) rows of tiny eyes.

    Thank you guys! With that info and after looking at pictures on BugGuide I think I can now tell the difference. We have a lot of both Agelenopsis and Rabidosa around our house. I like to know what I'm looking at.

    Yes they are awesome. I like seeing them around. I see them often when I cut the grass. (and I swerve to avoid them of course!)

    I let that one go, but I think sometime I'd like to keep a wolf.

    I went out into the yard and teased a grass spider out of it's web for a look. They are actually quite different from wolf spiders when you see them in person. I feel kinda silly for getting them confused. :eek:
