Light-winged

Light-winged Smoke, Icarian bird, Melting thy pinions in thy upward flight, Lark without song, and messenger of dawn, Circling above the hamlets as thy nest; Or else, departing dream, and shadowy form Of midnight vision, gathering up thy skirts; By night star-veiling, and by day Darkening the light and blotting out the sun; Go thou my incense upward from this hearth, And ask the gods to pardon this clear flame.

Light-winged ladies Aqua and Splash left the nest within moments of one another, but Spray didn't fancy the idea.

Next, I supposed it to be some gauzy, light-winged insect.
