Gorgeous coloring!
Tom, how are you getting all these to show their "underwing"?

 
A little nudge
Hi Lynette, once they settle in under the light, with their wings closed, I touch their back end, and they'll usually move a little without flying away, and after a few times, they stay opened up for a short while.

 
Hmmm
That works for me with moths of a certain size, I would say over 30mm head to tail. Anything smaller than that always seems to fly away.
