And the spider - another puzzle?

Having read the mystery moth/Scarce Umber posts, I'm tempted to try identifying the spider too... the nearest crab spider I can think of is a green but unmarked female Misumena vatia (they are quite variable in colour and pattern) though they are more often on white or yellow flowers - it's generally a more southerly species, though does occur in Ireland (but not on the NBN as it isn't in NI as far as I'm aware). Any thoughts?

Misumena vatia??

Hi,I also thought it might be Misumena vatia and as you say I have found it on oxeye daisies and dandelions ,yellow flowers.My first encounter was an Orange tip butterfly in late evening on an ornamental allium (purple)so not always on yellow flowers.
This spider has faint markings and I think it might be one I lodged as an observation last week called,Xysticus cristatus,
Kitnet suggested Xysticus ulmni as another possibility.I am new to computers and internet and can"t give you a direct link but its called "CRAB SPIDER ON FLOWER" if you would like to compare pictures you might be able to locate it.As I recall both plants were about 10 meters apart and it was on Knapweed too.
They are clever little fellows to catch prey so many times their own size.

Misumena vatia

I think I saw the other crab spider you mention - X. ulmi is found in damp marshy habitats earlier in the year (though I imagine the timing can vary). M. vatia is still my vote for this one, though far from certain.

Misumena vatia

I agree with dshubble on the spider - do you want to add it as an identification?

foxy - to add a link to your other observation, what I would do is:
1. scroll to the top of the page and right-click over the iSpot logo, choosing "Open in new window" (or you might have "Open in new tab" or something similar).

2. In the newly opened home page, either use the search box, or your "My Spot", to find your crab spider observation.

3. Once you've got your crab spider observation open, you should be able to see the web address ('URL') at the top of your web browser - click in to the web address to highlight it, then copy it.

4. Go back to where you started, i.e. to this current observation (which should still be open in your first window), and paste the web address into the comment text:
