ⓘ Angoumois grain moth

The Angoumois grain moth is a species of gelechioid moth. It is the type species of its genus Sitotroga, placed in the subfamily Pexicopiinae of the twirler moth family. Formerly, it was included in the "Chelariinae", which more recent authors do not separate from the Pexicopiinae and usually even do not consider a distinct tribe within them.

He now almost global distribution, including almost all of Europe and such distant places as Australia, Benin, Brazil, China, Indonesia, Japan, Samoa and the United States. This is due to its synanthropic habits, which makes it easy to transport in the field of international grain supply. Its common name refers to the Angoumois, a province of pre-revolutionary France, from which it was first scientifically described by G. A. Olivier in 1789. The province was reorganized into the modern Department of Charente next year, and as it so happened, you see not originally hails from Western France.

The wingspan of adults is 13-20 mm. Its larvae feed on grains of Asian rice starch, sowing, and millet Pennisetum glaucum, sorghum bicolor, wheat ears and corn Zea Mays. They carried the seeds of the host plant and feed inside the seed coating. Consequently, this moth is a pest of stored cereals. More unusual is the fact that the tracks have been recorded to eat other dry vegetable substances, such as plant specimens stored in herbaria.
