Host plants:
Polyphagous on herbs, particularly Galium species.
Habitat:
Amphipyra tragopoginis inhabits nutrient-poor grasslands, edges of woods, wetlands and similar areas.
Life cycle:
The eggs overwinter. I observed the caterpillars often resting on Galium verum-shoots during the day on the eastern Swabian Alb (May/June). The moths fly in summer between late June and September.
Endangerment factors:
Amphipyra tragopoginis is much less common than Amphipyra pyramidea and in decline through the uniformization of the landscape (intensive agriculture and forestry). But it is probably not under existential threat.
Remarks:
The overall distribution ranges from almost all of Europe to western Siberia and northern India. In the Nearctic, Amphipyra tragopoginis was introduced.
