A butterfly's fore and hindwings are not hooked together, which allows the butterfly to fly more gracefully. After the butterfly emerges from its pupal stage it can not fly until the wings are unfolded.

A newly emerged butterfly needs to spend time inflating its wings with blood and letting them dry before it can first take flight. This wing-drying process takes anywhere from 1-3 hours, a time period that makes the butterfly quite vulnerable to predators.

The color of butterfly wings is created by tiny scales. The blue color from this butterfly is created by the microstructure of the scales. This structural coloration is a result of coherent scattering of light by the photonic crystal nature of the scales. A butterfly's scales cling fairly loosely to the wing and come off easily without harming the butterfly.
