Ephestia kuhniella

Definition

A small moth species in the family Pyralidae, commonly known as the Mediterranean flour moth or mill moth. A cosmopolitan pest of stored cereal products, particularly flour and grain, whose larvae spin silken webs that contaminate food stores and facilitate moisture buildup, promoting mold growth. The species is favored in temperate climates and exhibits rapid development at warm temperatures, making it a model organism for studies on insect development, pheromone communication, and integrated pest management.

Etymology

Ephestia from Greek ephestios (domestic, of the hearth); kuhniella honoring German entomologist Heinrich Kühn.

Example

Infestations of Ephestia kuhniella in commercial flour mills are detected by pheromone traps monitoring adult male activity, with larval damage recognized by the characteristic silken webbing and frass in milled grain products.

Synonyms

• Mediterranean flour moth
• mill moth

• larval webbing

Usage Notes

Distinguished from the closely related Indian meal moth (Plodia interpunctella) by wing pattern: E. kuhniella adults have transverse dark bands on a pale gray forewing, whereas P. interpunctella shows a coppery distal patch. In laboratory settings, the species is sometimes referred to by its obsolete synonym Anagasta kühniella. The common name "Mediterranean flour moth" is somewhat misleading, as the species is now globally distributed in temperate zones through human commerce.
