Geometridae, pupa out of cocoon - Alsophila pometaria - female

Geometridae, pupa out of cocoon - Alsophila pometaria - Female
100 Acre Wood, Winneshiek County, Iowa, USA
September 14, 2011
Size: 7 mm
Question: Evolutionarily speaking, did this female moth have wings and then give them up? Because it looks as if the pupa has wing placeholders.

04-Jun-2011 Larva collected on Triosteum aurantiacum
17-Jun-2011 Notes say: "I think it made a cell in the peat" (at bottom of rearing container).
14-Sep-2011 Opened the peat coccoon to a perfectly formed pupa, but pupa completely still. Lovely color.
25-Dec-2011 Drat, a wingless female emerged and I completely missed it. She was in one of the rearing containers sitting right here, where I could keep an eye on it.

Interesting
All wingless moths are descended from winged ancestors, so those are vestigial wing pads in the pupal case. That's neat, I wouldn't have expected them to be there.

 
Yes, surprising.
At least one wouldn't expect them to be so well devloped.
