Insect

The bottom imago waits for all to appear and comes out!
So. The imago which emerged seems to wait for a few days until other cocoon are appearing.
And, he passes through the side of a cocoon of an upper small room and goes to the top when he cannot wait it. Ⅱ
When it is other kinds, and a cocoon of an upper small room is dead, he eats away the cocoon and advances to the top.
And it is the worst and when he cannot go to the top (the thing which is hard on a ceiling, strongly closed ceiling), he open a hole out of necessity on a wall beside a small room and go out. Ⅱ'

He advance to the upper part even if he invert a stem of a raspberry and go out. Ⅲ
They advance somehow towards the top and go out.

Then how do you become it in the case of stability? （Fabre took a direction of a cocoon to pieces）They are divided into right and left equally and go out. Ⅴ 　Ⅵ
（Fabre collected a cocoon of ミツバツツハナバチ and put a cocoon in tube of glass and Fabre made a small room and observed it and tested it）

It is a necessary experiment of perseverance!
I do remaked based on a cut and an explanation and color it.
