Edit seconds after: Because it would take a lot less energy for them to use. Good point. I originally had them with wings because their homeworld had a very thick atmosphere flooded with carbon dioxide; hence it took a lot less energy to provide lift against the denser medium and the benefits of flight more easily outweighed the costs.

Their new environment with its thinner atmosphere (though still thicker than Earth's) is not subject to this benefit, so wings make a lot less evolutionary sense. Frills it is then!
