Birds use their wing muscles to spread out their wings when they are ready to fly. Birds use thermal air currents, updrafts, and wind to soar and flap their wings when needed.
The TWA Building by Eero Saarinen at the JFK Airport in New York looks like a bird with spread wings just about to lift off the ground.

Some birds spread their wings before landing as a way to slow down and reduce speed. This technique helps them make a smooth and safe landing, especially when they are coming in for a landing at a higher velocity. By spreading their wings, they increase air resistance and create drag, enabling a more controlled descent.
The creature you are describing is likely a snake. Snakes do not have legs or wings, and they move by crawling on the ground. They lay eggs, and while they are not classified as bugs, they are fascinating reptiles that can exhibit unique movements that might resemble a dance.
It needs an engine to move it forward so that the wings generate lift. While stationary the wings generate no lift, or at least not enough to lift the plane off of the ground.
