Family: Brown House Moth & White-Shouldered House Moth: Oecophoridae Indian Meal Moth: Pyralidae Scientific Name: Brown House Moth: Hofmannophila pseudospretella White-Shouldered House Moth: Endrosis sarcitrella Indian Meal Moth: Plodia interpunctella Special characteristics: The Brown house moth and White-shouldered house moth are species that attack a wide variety of materials including cereals, cereal products, textiles, leather and cork. The Indian meal moth is a major pest of mills and all dried or growing material, and is a particular problem for the fruit-drying industry. It will also attack cereals, oil seeds and shelled nuts.
The Brown house moth has a 15 – 25mm wingspan with upper forewing a dark buff-brown with black-brown spots. The White shouldered house moth similarly has a 15 – 25mm wingspan with upper forewing buff-coloured and speckled brown. It closely resembles the Brown house moth, but can be distinguished because the head and thorax are covered in white scales. The Brown house moth tends to scavenge whilst the White-shouldered house moth is generally found infesting food. The Indian meal moth is smaller in comparison with a 10 – 15mm wingspan. The inner third of the forewing in pale yellowish buff and the remainder bronze coloured.
All 3 varieties are the more commonly encountered moths in grain stores in the uk. Both the Brown house moth White-shouldered house moth species are cosmopolitan and widespread on materials of animal or vegetable origin. The Indian meal moth is also a cosmopolitan species that originated in South America, and will survive all year round in warm conditions. It requires over 25% humidity to breed.
Family: Oecophoridae Scientific Name: Tineola bisselliella Special characteristics: Attacks animal products, for example wool, fur, skins and leather. Fibres are bitten off and the loose ends discarded, thus destroying much more commodity than is consumed.
10-15mm wingspan; upper forewing: pale ochreous buff, unmarked. Eggs are laid amongst fibres or scattered at random. Each female lays up to 160 eggs during a period of 2-3 weeks. During the summer these hatch in 4-10 days to give an active, white translucent larva. This grows up to 10mm in length and the head becomes darker in colour.
Common on animal products.

Family: Pyralidae Scientific Name: Ephestia kuehniella Special characteristics: Larval webbing can cause serious blockages in provender mills. The larvae eat holes in sifting silks and may also reach mill’s finished products.
Originated in Central America but now cosmopolitan. It is a particular problem in provender mills, bakeries and occasionally even in catering premises. One generation is usually produced, but in warm conditions adults will be present throughout the year when there may be 4-6 generations
Larval webbing can cause serious blockages in provender mills. The larvae eat holes in sifting silks and may also reach mill’s finished products.
20-25mm wingspan. Mating takes place immediately after the adults emerge. Up to 350 eggs are laid and these may be stuck to various foods by a sticky secretion. The eggs hatch in 4-28days to give white or pinkish larvae and spin silken tubes in which they live. After 3-5 moults the larvae are full grown and 15-19mm long
Family: Pyraloidae Scientific Name: Ephestia elutella Special characteristics: Moth Larvae can cause considerable damage to stored goods by feeding or by contamination with their own products. E.g. webbing and frass. Adult insects are not responsible for damage as they either feed on liquid food and water or do not feed at all.
12-18mm wingspan; dull grey-brown. Within 4 days of emergence, the female produces 100-150 eggs which are laid in cracks and crevices. These hatch in 10-14 days to give larvae which are creamy white with dark spots on their sides. They penetrate food, covering it with webbing as they feed.
Widely distributed throughout the temperate regions. It is rarely imported except on products from other temperate areas. A major pest of warehouses and, more recently, retail premises. This species will inf3est cereals, fruit, shelled nuts, cocoa beans, fish, spices and tobacco. Moth infestations are especially serious where wheat and flour are stored in bulk, although they seldom infest goods which are stored in silos.
Description Family: Dermestidae (skin feeders) Scientific Name: Anthrenus verbasci (Carpet Beetle), Anthrenus flavipes (Furniture Carpet Beetle), Anthrenus museorum (Museum Beetle), Attagenus pellio (Fur Beetle). Special characteristics: Carpet Beetle (including Varied Carpet Beetle, Furniture Carpet Beetle, Museum Beetle and Fur Beetle). Pests of animal products and occasionally food products of plant origin.
All carpet beetles are between 2-4mm long with the exception of Fur Beetle which is 4.5-6mm long. Variable colours, brown or black and mottled with yellow or white scales, the Fur Beetle are black, and covered in white hairs. Larval forms cause considerable damage to keratin-containing products such as wool, fur and leather. Occasionally food products of plant origin can be attacked. Damage takes the form of clean irregular holes in textiles. No webbing or excrement present and by the time larvae are observed, considerable damage has often been done. Carpet beetles are of limited significance as a health hazard, but are potential vectors of anthrax.
The varied carpet beetle is Indigenous to Europe and in England. The furniture carpet beetle is of a subtropical origin and cold sensitive. Carpet beetles are a major pest of textile. Warm, dry conditions are ideal for their development, but they can survive in foodstuffs of very low moisture content. Museum beetle is often found in museums where it is a particular pest of dried specimens. The fur beetle may be found in fur, skins, textiles and grain. Adult carpet beetles are found outdoors and live of pollen and nectar. Carpet beetle thrive in situations where they remain undisturbed, e.g. beneath carpets and around skirting boards.
