This insect, common in Great-Britain and Canada's West Coast, is an omnivorous scavenger of cereal screenings, dust, etc. Occasionally it is a major pest of bulk wheat, bagged flour and a variety of stored commodities. In the home it is much more important as a clothes moth than as a pest of stored foods. 1, record 1, English, - brown%20house%20moth

The adults vary in size with the male having a wing-spread of about 2 centimetres, while the female may at times exceed 2.5 centimetres. The forewings are dark brown with a number of blackish-brown spots. Approximately 300 eggs are laid by each female, most of them within a few days of mating. Three times as many eggs are laid on sacking as on grain. The mature larva is about 2 centimetres in length, shiny white in colour, with a yellow head. The feeding larva spins a light, closely-woven tube of silk as it eats its way through a food mass. When temperatures are too low, many of the larvae become dormant rather than pupate, extending the larval stage. High relative humidity is a requirement for satisfactory larval growth. At summer temperatures and a relative humidity of approximately 90% the life cycle takes about 100 days. 1, record 1, English, - brown%20house%20moth

Cet insecte que l'on trouve couramment en Grande-Bretagne et sur la côte ouest du Canada est un coprophage omnivore qui se nourrit de criblures et de poussières de céréales, etc. À l'occasion, on le trouve, comme ravageur principal, dans le blé en vrac, la farine ensachée et une variété de produits entreposés. Dans la maison, il cause beaucoup plus de dommages aux vêtements qu'à la nourriture entreposée. 1, record 1, French, - %26oelig%3Bcophore%20bronz%C3%A9e

La taille de l'adulte varie. Chez le mâle, les ailes ont une envergure d'environ 2 cm tandis que, chez la femelle, l'envergure dépasse parfois 2,5 cm. Les ailes antérieures sont brun foncé et parsemées de taches brun noirâtre. La femelle pond à peu près trois cents œufs, quelques jours après l'accouplement dans la plupart des cas. Elle dépose trois fois plus d'œufs sur les sacs que sur le grain. Au terme de son développement, la larve, d'un blanc brillant et présentant une tête jaune, mesure environ 2 cm de longueur. Elle tisse un fourreau de soie, léger mais serré, à mesure qu'elle creuse son chemin dans la masse des grains pour se nourrir. Lorsque les températures sont trop basses, de nombreuses chenilles connaissent une diapause au lieu de se chrysalider, prolongeant ainsi l'évolution nymphale. La chenille a besoin de conditions d'humidité relative élevée pour se développer de façon satisfaisante. À des températures estivales et à une humidité relative d'environ 90%, le cycle évolutif exige environ cent jours. 1, record 1, French, - %26oelig%3Bcophore%20bronz%C3%A9e
