Host plants:
The larvae are polyphagous, often on flowers. I found caterpillars for example at the base of Dianthus carthusianorum with partly eaten blossoms.
Habitat:
Ammoconia caecimacula inhabits nutrient-poor grasslands, edges and dry open forests.
Life cycle:
The egg overwinters. The caterpillar is observed from late April to June. Moths fly from late August to early October.
Endangerment: regionally endangered or decreasing
Endangerment factors:
Ammoconia caecimacula is in decline north of the Alps due to the loss of nutrient-poor grasslands.
Remarks:
The moth is widespread in Europe and Western Asia.
