You probably wondered why the dead insects lay up with their paws – as if someone had specially turned them over. The explanation, of course, is much more prosaic than it seemed.
In insects such as, for example, a ladybug, the body is rounded, and the legs are relatively small. The center of gravity falls on the back of the beetle, and after the death of the insect, the force of gravity does its job. Many insects would roll over on their backs constantly if the muscles of their paws did not work continuously.
Of course, a sick or injured beetle is already physically incapable of such work, which often leads to its “overturning”. Also note that a weakened insect is more difficult to take a normal position and often it can no longer stand on its feet.
