Egg: 0.25 X 0.15 mm.
Larva: 8 mm long.

Adults live for 12 days. Oviposition lasts 7 days. The number of eggs laid varies from 50-100. Females make several probe bites on the upper surface of leaves before inserting their eggs in superficial tissues at a depth of about 0.35 mm.
Larval development lasts 10 days, the larva passing through 4 instars. It forms a contorted gallery, vacating it at the end of its development to fall to the ground and entering to the soil to pupate.
Pupation lasts 36-65 days.

[R]Life Cycle
There are several generations per year, both outdoors in the South of France or in protected areas further north.
