Flower Crab Spider - Misumena vatia - male

Flower Crab Spider - Misumena vatia - Male
Enumclaw, Forested Unincorporated King County, Washington, USA
October 7, 2009
Size: 4mm
This immature male had just caught a small flying beetle. I don't know what kind of flower this is that we have, but there were many generations of flower crab spiders living on them. Now that the weather is bad (and we just had a wind storm) there are practically no flowers left. I saw a lot of the spiders ballooning away two days before the storm. It's like they 'knew'!?

I tried to use John and Jane Balaban's article on the eyes of Misumena, Misumenoids, and Misumenops. But since I couldn't even decide if the ALE on my spider were bigger than the AME, I didn't get very far. Ha. I do know that I can only see the six eyes (PLE are hidden behind 'brow')...so does that rule out Misumena?

ID to species via Rod Crawford:
"any Misumena you find automatically has to be M. vatia. It's the only
species in N. America and possibly the only species that really
belongs in this genus in the world (there are several others listed
from various countries but mostly nobody's seen them for a generation
or more)."

I second Misumena
The absence of thoracic setae and the configuration of eyes suggests Misumena to me as well. Misumenoides has a clearly defined ridge on which the eyes are located and Misumenops is extremely hairy.

Not an ID but
makes me think Misumena vatia, but I'm no expert.

 
Thanks guys!
My first impression when I see a crab spider in our flowers is usually Misumena vatia...but after the article written by the Balabans, I'm never quite sure anymore. I'm glad to have some unbiased eyes check it out for me. And I bet you both are right. Thank you!
