Question

asymmetrical or symmetrical, asymmetrical

Explanation:

To determine if the butterfly is symmetrical or asymmetrical, we check for symmetry (mirror - image match on either side of a central axis).
The butterfly's wings and body show a mirror - image pattern when divided along the vertical central axis. So, it is symmetrical. The "asymmetrical" label in the yellow box does not apply to the butterfly.

The butterfly has a mirror - image pattern along its vertical central axis, so it is symmetrical (not asymmetrical as the yellow box suggests for other elements, but the butterfly itself is symmetrical).

Answer:

The butterfly is symmetrical.
