In fact, the beetle will lie on the beer bottle, mainly because the male beetle patrolling in the air is looking for a healthy, strong female beetle suitable for their mating.
So when they look at the glittering beer bottles on the ground, they are instantly overwhelmed by love. Usually, they will try their best to swoop down from the air and stay on the bottle.
Of course, it’s not just beer bottles. If you wear a beer bottle of color and are squatting at the sun, they will also squat from the air and throw you down!
