In autumn, larvae are easily tapped from Urtica. [N]

Host plants:
The larvae are polyphagous, but often observed on Cirsium, Urtica or Lamium.

Habitat:
Diachrysia chrysitis is an ubiquist, but is usually found in at least slightly moist forb communities.

Life cycle:
Diachrysia chrysitis has two generations in the summer (especially June to early September). The young caterpillar overwinters.

Endangerment factors:
Not endangered.

Remarks:
The partially separated from this species Diachrysia tutti (the gold spots on the forewings are connected by a bar) is possibly not a genetically separate species, but this is not fully understood.

The distribution of the two taxa ranges from Europe to East Asia.
