1, which can be achieved by zooming in/out. After adding the zoom-out animation, you will find that the zoom-out is based on the center point of the object. So first of all, we need to change the center point of the butterfly's wings, which requires copying his wings to make them transparent, and then combining them with the previous wings (as shown in the figure, but pay attention to finding the center point in the body position, so as to narrow the wings from the body part).

2. Add a zoom-in/zoom-out action, and set the action properties as shown in the figure below.

3. Animate the other wing in the same way. After the animation of wings is finished, you need to add path animation to the butterfly. Choose the butterfly's wings and body at the same time and add path animation to these three objects together, so that the butterfly can fly ~
