Crab Spider - Mecaphesa

We've been working on Thomisidae recently

In the Great Lakes region we only have Mecaphesa asperatus and M. celer. So far, this doesn't look like either of those :(
That leaves two possibilities. Either Misumena vatia as you first suggested, or the female of Misumessus oblongus. We haven't seen an image of the second yet, so we don't know what that looks like, unfortunately. We'll keep trying to figure these out.

I've been looking

For a picture of a female Misumessus oblongus, and haven't been able to find one yet. I sure appreciate all of your efforts. I'll keep looking :)

Not Misumenoides,

but likely Mecaphesa, instead - different anterior eye size and lateral eyes on tubercles.

Mecaphesa

Thanks! I didn't even notice the hairs on the cephalothorax until I read your comment. She must be Mecaphesa - probably one of the "unknown" species. :)
