Moths in heaven on Jasmine?

Does anyone know the story behind the phenomenon of this moth and Confed. Jasmine (Trachelospermum jasminoides)?
I had not noticed this in previous years, but these little moths seem to be drawn to it. They start out like the one in the photo, and then
the next day, I notice they are still there but appear to have died. It's almost like they got stuck and couldn't get away - either that or
they just died from happiness...or they're not dead- just intoxicated.

Anyway, very odd - just wondering if someone knows. I've searched around but no luck.

Thanks!

Interesting and a good clear photo. It appears as though the moth's proboscis is still in the flower, makes me think of cruel plant (Araujia sericifera) which traps moths by their proboscis until daybreak. Maybe this moth got stuck and couldn't roll his proboscis back up, then died of hunger/exhaustion?

That's what I thought the first time I saw one, but it's not just the one but a several every day.
I will look up that arauijia and see if that will lead me to an answer.
Thanks for the reply!

Still haven't figured it out, darn it, so I'm posting this over on the insect I.D. forum.

If I find out the answer, I'll post it back here.

Thanks to everyone who has looked, nevertheless! :)
