This is the shape of the cocoon before it turns into an adult ladybugs. Ladybugs cycle process:
The larvae that have reached a certain size will then stop feeding and enter the cocoon phase at the age of two weeks from the first hatch
This cocoon usually attaches to objects such as leaves or twigs and is yellow and black. Ladybugs will then come out of the cocoon after about a week.
the new wing of ladybirds is still fragile and pale yellow, so he will stop to tighten his wings before starting the movement.
