Moved from Spiders. Thank you Kevin for getting Levi to ID this. I've been following since the beginning, it is a very interesting/beautiful spider.

Nice one John!

Maturity/Gender

Because I have found two subadult males in the fall/winter it would make sense that they probably become adults in the spring/summer. Circumstantially, based on the time of year that this one was found, the slightly larger size, and the color difference I assume that this one is an adult. If it is an adult it would then be a female. I have marked it as adult female for now, but will continue to investigate next year trying to find color patterns and seasons for gender and maturity.

What a cool spider!

I've been trying to find a match for this one for a while... If you have other images, please upload them if you get a chance. I don't suppose you'd be interested in posting these images (or having me post a link to them) on the Canadian Arachnologist's Forum?

Thanks for commenting. I had considered frassing as general clean-up, but I haven't found anything close so I wondered if this might be new to BugGuide (or I'm just looking in the wrong place).
As suggested I did post here http://forum.canadianarachnology.org/viewtopic.php?t=350
Fingers crossed :-)

See the end of this thread in the Nearctic Forum for the solution to this puzzle.

Kevin, I used your better image here. If you could send me an email explaining what you did that would be great.

Belated reply -- all I did wa

Belated reply -- all I did was adjust the color balance to remove some of the yellow cast. This is generally an automated function if you have a grey-scale or other color neutral area in the image to use as your reference point. I think I used the little bit of white in the dorsal area of the abdomen and then tweaked the result slightly.

Thanks everyone

Wow, go away for a little NJAS Bird & Bug workshop in Cape May and miss all the action! Thanks! Hopefully it is out there making more Araneus partitus fo all to enjoy.

Wonder if it might be something in Mimetidae?

Compare with

for example?? The legs just don't look long or delicate enough. We, too, are eager to hear what the experts have to say.

Maybe

These are the images that attracted me to Araneus

Along these lines -

Kaston described Araneus miniatus as being "yellow, with dark paired spots on the posterior half of the abdomen, and a broad white transverse band between the shoulder humps"(1). Perhaps this is a bright yellow variant of that species? Not at all sure, of course... Our very limited sampling of miniatus in BG, one of which you've placed in your last post, may not be represenative? Do you think the colors in your images are pretty true-to-life, John?

Yes, colors are very close to true.
