1. According to phototaxis, ladybugs will fly close to the light source. Because the distance between the two eyes and the light source is different, one eye feels stronger than the other, and the ladybug will constantly turn to the direction with stronger light, thus forming a circular behavior.
2. Ladybugs create an air vortex in front by rotating their wings, which reduces the air pressure in front, so the air flow rises from bottom to top and blows their wings to form a circle effect.
