- [Poaceae:] Elymus athericus [= Elytrigia atherica] (Strand-Quecke)
Beaumont (2004: 159) verwies auf ein Ausstellungsobjekt: "Langmaid, J.R. Psamathocrita argentella P.& M., Southsea, Hampshire, a series of six reared from seeds of Elytrigia atherica collected 10.ix.2002, moths emerged vi.2003. The first time that this species has been reared." Bei Gregersen & Karsholt (2022: 241) heißt es dazu: "The biology has been studied by Langmaid and Thirlwell and is here referred from Bland (2002: 98-99): [...] Host-plant. Elytrigia anthericus. The larva feeds on the developing flower and seed, extruding whitish frass which can sometimes be seenadherinmg to the spikelet; it is unknown whether the larva leaves the feeding place to pupate or remains inside the spikelet and - together with this- drops to the ground in late summer (Bland op. cit.). [...] After unravelling the biology, larvae were found in numbers in a few localities in S England." Bei Bland (2002: 98) war zur Eiablage zu erfahren: "Ovum. Laid deep inside a floret of sea couch (Elytrigia antherica. Ovipositing must be a hazardous act, as several moths were found dead or dying with their ovipositors firmly trapped in the spikelet by the stiff scale-like glumes and lemmas Sea couch was originally suggested as the foodplant by Ffennell (1974) who observed many moths running up the grass stemms and resting with wings partially extended."

3.1. Faunistik
Die Art wurde aus England beschrieben und scheint dort an Küstenbereiche mit Salzmarschen gebunden zu sein. Aus Frankreich gibt es auf der Artseite von [openobs.mnhn.fr (abgefragt 22. Oktober 2021)] eine Fundmeldung von Antoine Guyonnet vom 8. Juni 2007 im Marais d'Yves - also ebenfalls einer Salzmarsch - im Département Charente-Maritime in der Region Nouvelle-Aquitaine. Der Fund wurde als Erstnachweis für Frankreich durch Guyonnet & Lemoine (2017) publiziert und diskutiert.
Timossi (2020) meldet den Erstfund für Italien: 1 Männchen im Riserva Naturale Regionale Integrale “Bosco Nordio” in Venetien.
Huemer (2024: 29) überrascht mit dem Erstfund für Griechenland: "Larisa, 1 km NW Alexandrini, 1 m, [...] 15.vi.2023, leg. Huemer, DNA Barcode ID TLMF_Lep_38895." Er kommentiert: "The strongly isolated record from Greece represents the southern-most occurence of the species."
