The drill fly species mainly uses the field marigold ( Calendula arvensis ), the subshrubric marigold ( Calendula suffruticosa ) and the French feltwort ( Filago gallica ) as host plants . The larvae develop in the flower heads of their host plants. Drill flies can be observed from the beginning of June.
