No-it didn't crawl on it's back-it just seemed to have trouble moving at all-like trying to "unbend" itself. It was trying to right itself by biting the towel I had it on.

Thanks ^_^ - I usually do well with photos of "larger" bugs-it's the tiny ones that give me trouble.

I'll look that name up and see if it matches anything I've seen around here.

it did crawl on its back. It is doing it on this picture!
They are called "crawly backs". See here.
Where I live, UK, I've got loads in my compost piles this year, they will pupate soon. Ours are Cetonia aurata, a lovely green jewel like beetle.

No, it didn't it was trying to turn over.

But I'll at those anyway.

Jo, why not trying to keep one or two to see the results after pupation? Your photos are very nice, and that way one could have the following up results for the guide.
Back to the photos, their rear ends are very important, so perhaps more photos of that too. See this for an idea of what you should be looking at.

Oh that's cool-I can only wish they were something like that ^_^

I did set them up in compose as they were before but in a container, how long do they take to go from grub to beetle?

BTW-if those are what are you said-I'd be thrilled to see as I never have here before.

Thanks ^_^

Mine have pupated already. They make their coccons out of soil and they look like a small bird's egg. See here in the Cetonia aurata column. They are very fragile, take care when you look...
As for the resulting beetles, perhaps you aren't looking in the right places... They love sitting on flowers and fly with their wing cases down so that they look like bees. Lovely beetles ;-)
Good luck and keep me posted.

So far they are basically the same-unchanged-how long do they usually take from one stage to another?

I can't imagine I haven't spotted one of these-as my porch is totally covered with flowers every year. See?http://www.deviantart.com/view/36201630/ ^_^ Unless they like a different kind of flower (not all mine have flowered yet-BTW)

The pupal stage isn't very long, however the imagos will stay underground and emerge next spring, I think. Meanwhile the ones that have emerged this spring will be laying eggs, possibly in your compost, thus the cycle will continue...

If these guys don't pupate by fall I have keep them till next spring right? what's the best way to keep them-indoors or outdoors or..

Thanks ^_^

is the key. I believe that they will be pupating before the fall; meanwhile make sure that they don't run out of food. A shady place in the garden would be good, but in the winter bring them in to an unheated place, a garage maybe.
As for the flowers they are very specific. Over here, UK, they like thistles, for instance, and some flowers of the carrot family.
