Spider ID #1 of 2 - Araneus Spider ID #1 of 2 - Araneus

Moved back to genus level for now
Moved from Marbled Orbweaver. I think it might be something other than A. marmoreus, possibly just an odd-looking Araneus diadematus, but moved back to Araneus for now until we can look at it again. It kind of stuck out to me on the data map because A. marmoreus isn't a common spider in CA, and not found at all in some of the arid SW states. (Though I think it's totally possible in northern CA.)

Pumpkin Spider
Confirmed ID this morning from entomologist/arachnologist at the California Academy of Sciences. Long live the spiders!

 
A. gemma - Pumpkin Spider
would make sense. Large, orange, and matures in the fall. More here.

 
Rod Crawford
thinks this could be Araneus marmoreus.

 
Also known as...
Shamrock Spider - Araneus trifolium - same genus as Marbled Orb Weaver, so that was a good guess. We have more images here. The color is highly variable, by the look of it. You could tag these and move them to the guide if you like - we have none from California yet. Just tag and follow the link above, then "move tagged images."

 
THAT'S a shamrock spider?
Wow! I never would have guessed:-) Thanks, Hannah.

 
Hey, the ID is not mine
I just tracked down the common name. I am trusting the guy in CA knows his stuff :). The common name pumpkin spider led me to this website BugPeolple.org, and it makes sense with this nice color. It definitely has the Araneus look, but the species ID is beyond my capabilities. Feel free to disagree!

 
Don't quite follow you...
Thanks, Hannah, for your comments. I tried to do as you advised, but not sure that I did it correctly as 1) not sure what link you were referring to to follow and 2) didn't see the "moved tagged images" option. Sorry to be so naive, I'll get the hang of this yet! Lori

 
Not to worry
it takes a while to get used to the navigation. You might do better just reading the Help option (near the top of every page). I or any editor can move these for you, but it is (I promise!) easy to do yourself.
The link is the one I gave you in my comment, above, "We have more images here" - the word "here" leads to the image page for this species. Hit "tag all" (under your picture), follow the link and then hit "moved tagged images"(on the image page).

 
Link success!
Your patience and explicit directions were the key to my success. Thanks ever so much, as you will see, the link worked. Now I can't wait until my next mystery visitor arrives, this has been such a great experience and I'm truly in love with this web site. Never knew it existed, it'll be great to finally have a place to share our bug/spider/insect enthusiasm. Awesome!

 
I agree,
I'm totally hooked, having been a user and contributor for more than a year.
I'm glad you managed to move these OK. We all have Troy to thank for making it so user-friendly!

Marbled Orb Weaver? Please c
Marbled Orb Weaver? Please confirm, thanks.
