[R]Description
Adult: 2 mm long; head with upper part black and lower part yellow; thorax black with yellow spots on the back; abdomen alternately striped with yellow and black (*) .
Egg: 0.25 X 0.15 mm.
Larva: 8 mm long.

[R]Biology
Host plant: celery.
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.

[R]Damage
Infestations spread to cotyledons and terminal leaves. Larvae form mines between the 2 epidermal layers of leaves, along the main vein and adjacent tissue.
