Celery fly

Description, Biology, Life Cycle, Damage, Common Names, Images

- Adult: length 5 to 6 mm. The summer generation flies are relatively pale, red-yellow, with pale heads. Those of the winter generation are shiny black. All have dark, striped wings(*) .
- Larva: very small maggot.
- Egg: laid in small groups on the leaves.

- This fly is dependent on celery and certain other Umbelliferae.
- Adult: the first generation appears in May. The female lays a maximum of 150 eggs on the leaves from which the larvae develop. The following generation appears in June.
- Larva: development takes 25 to 30 days. Several mine the same leaf and several in the same mine. During major attacks, they form galleries in the petioles.
- Pupa: usually hibernates in the ground at a depth of 8 to 10 cm and more rarely, in the leaf (*) .

[R]Life Cycle
-Two generations per annum. The first flies appear in May, the second generation occurs in July.

-The leaves are covered in mines; collective mines appear as a large white mark. The frass is clearly visible through the two transparent leaf epidermis (*) . The leaves appear burnt and dried-up (*) . Deprived of a large area of leaf, the celery produces a sickly bulb.

Europe and Asia Minor.
