Hummingbird Clearwing - Hemaris thysbe

Hummingbird Clearwing - Hemaris thysbe
Town of Gibraltar, Door County, Wisconsin, USA
Pupa was given to me by Kathy Presnell, of Fish Creek, August 12, 2002. It overwintered in our fruit cellar. Removed pupa from fruit cellar April 24, 2003. This individual is newly eclosed. Note that the wings are rather opaque. It took about 24 hours for them to clear.

Seen one
I've seen one at camp feeding on flowers. But at the time I don't have a camera. It was interesting to watch.

 
Hummingbird Moth
The first time I tried to photograph one of these moths, I was using a tripod and slow-speed film. By the time I got everything set up, the moth was in the next county. That prompted me to get a hand-held, automatic camera. Up until then I had been photographing wildflowers, shrubs and trees. That incident was the beginning of photographing insects...didn't have a clue what I was getting into at the time!!! In order to get a photo like mine, you almost have to rear them, so when they eclose, they think you're their mother. They are very docile and will easily pose for you. Commission all your friends to be on the lookout for a larva for you.

Opaque Wings
The 'opaqueness' is caused by very loosely attached scales. The wing membrane is clear as in all lepidoptera. In this group there are patches with much fewer scales than normal and these scales are loosely attached. The moth vibrates its wings and these scales are thrown off leaving clear membrane areas.

 
Great answer
I've often wondered about the opaqueness of the wings when newly eclosed, but could never find an explanation. Thanks!
