Moth's don’t turn into dust when they get killed. The dusts from their wings are actually tiny scales made from modified hairs.
Moths, like butterflies, belong to the order Lepidoptera, which means 'scale wing'. It loses a few scales every time it flies or lands on a flower to feed; even windy weather can remove them.
Although the scales help slightly with aerodynamics, they aren't essential to flight, so a moth can still get around even when missing most of his scales.
