uncommon species in Belgium, but as with many members of this
family, it's often overlooked.
larva lives in a brown tubular silken case on Tanacetum vulgare
usually attached to the flower heads. It rarely behaves as a leafminer
and generally it lives in the inflorescense of the food plant.
Pupation in the case.
The adults fly from late May towards July.
