Actually, I have experienced drooping or slight change of wing position
problems upon submerging specimens in acetone (it does not happen
frequently). (You may also notice the edges of the wings curling as the
solvent volatilizes.) If there has been a slight wing position change, you
can reset the wings *immediately* upon removal from the solvent (before it
has dried), assuming the change is not appreciable. The specimen will at
best be only slightly flexible.
