The Cicada : laying

From mid-July, the cicada lays 300 to 400 white, 1/10-inch long and 1/50-inch wide eggs, which are conical at both ends, simular to tiny shuttles.

The Cicada entrusts its laying to a branch or dry bough, size of a straw to a pencil. It selected a mulberry tree, cherry tree, willow, the dry asphodel (bulbous plant with white flowers) to the long and smooth stem.The cicadas “tibicina haematodes” and “Pygmy” prefer the green branches.

The cicadas always lay the head directed to the top, except the cicada “Pygmy” who lays head towards the ground.

To plunge its eggs in the marrow of the branch, the Cicada is provided with a oviscape (kind of drill), which creates a scratch, as a from top to bottom pin plunged obliquely would do it; by the raised woody scrap, our insect deposits from six to fifteen eggs, withdraws the double saw of the drill, the scrap is closed again, our Cicada assembles few centimetres and starts again sowing, and thus, this operation will repeat thirty to forty times, on one or more stems.

During September, the eggs pass from the white to the fair one; at the beginning of October, the eyes appear and the blossoming with place by a beautiful sun of autumn.

By the stem split at the time of the laying, appear the primary larvae, left tiny fish with a ventral edge (sheath where the legs are placed). The larva tears this provisional sleeve and is extracted some. This défroque is retained with the brushwood by a filament.

Our larva remains in this suspended cup, time to take a sun bath, to harden itself and to take forces, the fair one it passes to amber.

Finally the fall on the ground takes place. Without delaying, the larva starts to dig to go down in the ground. It digs with its legs of front, which cut the roots which obstruct it.

Our Cicada begins its four to six years of underground life.

Some their American cousins drill the basement up to seventeen years, before leaving for their last moult.
