- Host plants: wild and cultivated carrots, celery and more rarely, parsley (*) .
- Carrot fly overwinters as a pupa; the adults appear over an extended period, from the end of April/beginning of May until July. The flies take flight on fine days, flying slowly, landing frequently on the leaves of a large variety of low-growing plants. They mate and lay eggs shortly afterwards in the ground near host plants. Embryo development: 10 to 12 days.
- Larva: moves in the soil and penetrates the root, forms twisting galleries, notably in the external layer (*) . Larval development lasts one month after which it pupates.
-2 generations per annum, a 3rd in the autumn in some regions.
-The first-generation larvae develop on new carrots and the flies appear from July to September, producing very harmful 2nd-generation larvae, which cause damage to carrot crops right up to October-November.
Attacked carrots are stunted; they frequently rot and acquire a bitter taste (*) .
In Germany: 2 generations per annum. Highest larval feeding activity in August. 2nd generation overwintering as larvae inside the root (which makes the damage more severe) or as pupae.
