3.2. Lebensweise des Falters

Zum Lebensraum und zu den Faltern schreiben Landry et al. (2017): "Adults fly from late June to July in mountain steppe slopes at altitudes from about 1500 m to above 2000 m. Thomann (1956) found the species in late June 1923 and 1926 on meadows near anthropogenic heaps of stones covered by short vegetation. The moths were not attacked by the extremely common ants in this microhabitat and Thomann concluded an eventual myrmecophily."

4.3. Taxonomie

Landry et al. (2017) vermerken: "Two females collected on the same date at the type locality of muestairella (Santa Maria, Münstertal, Switzerland, 29 Jun 1923) display marked differences in genitalia. Considered individually, each of these could be construed to represent a different species, as divergent from each other as they are from any of the other three species for which females are known. This throws some doubt as to the validity of the species based on single females. At this point we elect to keep them together because it would be unwise to describe them as different species or to resurrect muestairella as valid without additional specimens and DNA barcodes."

Möglicherweise gehört also auch Agonochaetia quartana als Synonym hierher.

4.4. Faunistik

Landry et al. (2017) fassen zusammen: "Known from isolated localities in southeastern Switzerland, Albania, and Romania".
