Pyralis pictalis
The Painted Meal Moth or Poplar Pyralis (''Pyralis pictalis'') is a snout moth (family (Pyralidae). It is closely related to the family's type species the Meal Moth (''P. farinalis'') and consequently belongs to the tribe Pyralini of the snout moth subfamily Pyralinae. Its native range is tropical Asia to East Asia and to the Wallacea and adjacent regions, but it has been quite widely (though involuntarily) distributed by humans. The term "Poplar" in its common name does not refer to the trees, but to Poplar, London, where type specimen – from such an introduction – was caught. It was called Scarce Meal Moth in the original description, which is only correct for the fringes of its range however.〔Curtis (1834), Clarke (1986)〕
While the caterpillars of this moth are most notable as a stored-food pest, they may themselves be useful for biological pest control as under certain conditions they will eat other insects' eggs.
==Distribution==
It is not known precisely where this moth originated, but it seems to have been the general region of Southeast Asia. Presumably, the Painted Meal Moth natively ranged from southern India and Sri Lanka northeastwards to Japan and southeastwards at least to Sumatra, Java and at least parts of Borneo; perhaps its natural range extended as far as the Philippines in the east, and to New Guinea or even Fiji in the southeast.
But the latter population, widely isolated as it seems, may just as well be a colonial era introduction, as may be the case for the records from Australia (beyond the Wallacea, as seen from its core range) and northwest British India (beyond the Himalayas). In Polynesia ''P. pictalis'' was recorded beyond Fiji from Kiribati and from Hiva Oa in the Marquesas Islands, presumably fairly recent introductions. In Africa it appears to be absent from the east, but has been found in Belgian Congo and West Africa, as well as in South Africa. Finally there are of course the records from England and other European localities; in brief, outside its contiguous range the moth mainly occurs along the historical East Indiaman trade route. However, this moth tends to occur ephemerally outside its presumed core region; in temperate and even in subtropical Europe for example the species does not seem to have established a self-sustaining population and may in fact for all practical purposes be considered absent.〔Clarke (1986), ABRS (2010), FE (2011)〕
