Characteristics and Distribution
The common grain moth is widespread in the western Palearctic. It is common in the UK but may be absent in some places. It has not been recorded in France and Slovenia, but this may be due to omission or confusion with similar species. Adult moths have a wingspan of 10 to 18 mm. Their wings are irregularly mottled in black, white and grey, which allows them to be distinguished from other species such as the cork moth.
Ecology and Behaviour
In their natural habitat, the larvae of the common furniture beetle feed on rotting wood, although they prefer tree fungi, mainly from the Polyporaceae family. In the human environment, the larvae feed on various dry organic materials such as dried fruit, cereal grains, flour or cork.
Synonyms
Due to its widespread distribution and frequent descriptions, the granary moth has many scientific synonyms, which are now considered obsolete.
Summary
The grain moth is a fascinating species of moth which, despite its small size, can cause significant damage in grain warehouses. Its ability to adapt to different environmental conditions makes it a difficult pest to control.
