Crab Spider ID?
Copyright © 2009 Ray Lemke

Crab Spider ID?
Milwaukee, Milwaukee County, Wisconsin, USA
July 21, 2009
Size: 4-5mm
I have no idea of habitat, as I found this small spider on the outside of my car window in the parking lot of a nature center. I assume this is a crab spider. The body was pure yellow. the rest including the legs had a very slight tinge of green to the yellow. Can anyone ID the species?

Misumena vatia
I believe this is Misumena vatia based on the abdomenal apodemes (dimples), the rounded posterior abdomen, and the projection of the abdomen over the cephalothorax.

We were cleaning up some of the not yet ID'd groupings we made
Our understanding now is that all Mecaphesa have hairy spines on their carapace, so we don't know what to make of this and decided it made more sense on the family page.

We're thinking there are some non-hairy Misumenops
Oh, for an expert! So all the hairy ones are Misumenops, but the non-hairy ones are not necessarily other. That's our firm position and we'll change it in an instant when an expert comes along to help us with this genus!

(We can also convince ourselves that the anterior lateral eyes are larger than the anterior medians, which rules out Misumena and Misumenoides.)

Eye eye eye...
Well, I heavily rely on the hairs on these. I think you are correct about some being unhairy. The genus description says 'tends to be hairy'. I'll follow your lead on these as I think you're the crab spider expert.

We would suggest Misumenops
We would think, from this angle, if it were Misumena, you would easily see the posterior lateral eyes.

Hmmm...
where are the telltale hairs? :)
