|We allow Ragwort Senecio jacobaea to grow in parts of our garden for this species. At this time of year the moth lays it eggs on the unopened buds of the plant (also of Groundsel S. vulgaris). Ragwort is deadly to horses, which can avoid the green plant but not dried foliage in hay, so it it not tolerated in meadows.

First instar and two second instar:
Note the chewing damage to the unopened buds.
Happiness is having the right adapter.
