3.3. Faunistik
Die Art ist nicht in Europa heimisch! Goater (1986) schreibt: "Four specimens recorded from the nurseries at Enfield, 26 October 1978, 15 March 1979, 25 May 1979 and 7 June 1979. Originally described from Australia, and known to range from there through Malaysia." Goater et al. (2005) erwähnen sie im "Appendix: List of acentropine species introduced to Europe by man" mit dem kurzen Text: "Recorded from Great Britain (Agassiz (1981: 25; Greatorex-Davies, 1991) and the Netherlands (Kuchlein & de Vos, 1999: 128). Native to the Oriental and Australian Region." Agassiz (1981: 26) geht davon aus, dass die Tiere in England im Raupenstadium eingeschleppt wurden und sieht trotz der Verteilung der Funde über eine Spanne von mehr als 7 Monaten keinen Hinweis, dass es hier zu einer Folgegeneration gekommen sein könnte.
Nach neueren Funden geht die FERA (Food and Environment Resaerch Agency) (2013) auf die Art ein und schreibt in ihrer "Recommendation for interceptions and findings of Parapoynx polydectalis (Lepidoptera: Crambidae), a species of moth whose caterpillars are aquatic": "An adult moth of Parapoynx polydectalis has been reared from an aquatic caterpillar intercepted on 27 August 2012 on Cabomba (an aquatic plant) from Singapore. It has previously been recorded in the UK in 1978 and 1979, (a total of 4 specimens, over 2 years) at aquatic nurseries in Middlesex (as Oligostigma polydectalis). There are a further two records of incidental single specimens from 1988, one a dead specimen on the windowsill of a tropical aquatics shop in Devon, and the other inside a tropical fish aquarium in Cambridgeshire. There have been several interceptions of caterpillars from this genus, several consisting of more than one larva, in the past two years, though few have been successfully reared for species identification. All consignments originated in Indonesia or Singapore and consist of plants for planting, potentially allowing the pest to complete its development."
Agassiz et al. (2013: 112) führen die Art bei den "adventive species" und schreiben zu England: "Occasionally imported with aquatic plants, only survives in heated greenhouses. Oriental."
Bei Kuchlein & de Vos (1999: 128) wird zu den Niederlanden berichtet: "[22] Twelve specimens of Oligostigma polydectalis (Walker, 1859) were recorded from Amsterdam in 1980 and 1981 (det. M. Shaffer). The species was introduced from Malaysia with aquatic plants (C.W. Hemker, in collection Zoological Museum, Amsterdam. Not reported earlier from The Netherlands. There is no evidence for the occurence of O. polydectalis in aquatic nurseries in our country."
Die Art dürfte in Europa zumeist nur in warmen Gewächshäusern leben können - bisher gibt es aber auch dort noch keinen Hinweis auf eine langjährige Etablierung.
