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.
There are several generations per year, both outdoors in the South of France or in protected areas further north.
Infestations spread to cotyledons and terminal leaves. Larvae form mines between the 2 epidermal layers of leaves, along the main vein and adjacent tissue.
