    Habitat

    Where Mugwort occurs.

    When to see it

    Mugwort flowers in July to September in Europe, so populations of Macrosiphoniella artemisiae usually peak around this time. It is commonly found on the flower heads with other species of aphids in mixed species populations.

    Life History

    The Mugwort Aphid lives on the upper parts of Mugwort (Artemisia vulgaris) especially amongst the flowers. Sexual forms occur in the autumn, and the species overwinters as eggs.
