They hatch when growth of the vegetation starts again and aphids infest the underside of leaves. 3-5 generations of fundatrigeniae may occur on the primary host. Winged forms emerge in late April-early May and migrate to secondary hosts. In autumn, alatae appear and, after returning to primary host-plants, give birth to oviparous females.
Males born on the secondary hosts migrate and the sexual generation is produced.
Alatae produced in February-March leave early, as soon as climatic conditions are favourable. Bracts on artichoke become red and harden.
