Ephestia elutella, the cacao moth, tobacco moth or warehouse moth, is a small moth of the family Pyralidae. It is probably native to Europe, but has been transported widely, even to Australia. A subspecies is E. e. pterogrisella.

Contents

The wingspan is 14–20 mm. Forewings in male are less elongate, [ than other Ephestia ] with costal fold enclosing flocculent scales; grey, sprinkled with whitish and mixed with dark fuscous, towards dorsum often also with ferruginous-reddish ; lines pale, dark-edged, first straight, rather oblique, second almost straight ; two darker transversely placed discal dots. Hindwings pale fuscous, anteriorly thinly scaled, in 6 with median and subdorsal whitish-ochreous basal hair tufts. Larva brown-whitish ; dots brown ; head and plate of 2 reddish brown: on biscuit, chocolate, figs [1] [2] [3] [4]

This moth flies throughout the warmer months, e.g. from the end of April to October in Belgium and the Netherlands.

Infestation

The caterpillars of Ephestia elutella are often considered a pest, as they feed on dry plant produce, such as cocoa beans and tobacco, as well as cereals and dried fruit and nuts. Less usual foods include [5] dried-out meat and animal carcasses, specimens in insect collections, and dry wood.

Tobacco and its related products can be infested by Lasioderma serricorne (tobacco beetle) and Ephestia elutella, which are the most widespread and damaging parasites to the tobacco industry. [6] Infestation can range from the tobacco cultivated in the fields to the leaves used for manufacturing cigars, cigarillos, cigarettes, etc. [6]

<span class="mw-page-title-main">Pyralidae</span> Family of moths

The Pyralidae, commonly called pyralid moths, snout moths or grass moths, are a family of Lepidoptera in the ditrysian superfamily Pyraloidea. In many classifications, the grass moths (Crambidae) are included in the Pyralidae as a subfamily, making the combined group one of the largest families in the Lepidoptera. The latest review by Eugene G. Munroe and Maria Alma Solis retain the Crambidae as a full family of Pyraloidea.

The Mediterranean flour moth or mill moth is a moth of the family Pyralidae. It is a common pest of cereal grains, especially flour. This moth is found throughout the world, especially in countries with temperate climates. It prefers warm temperatures for more rapid development, but it can survive a wide range of temperatures.

<i>Orthonama obstipata</i> Species of moth

Orthonama obstipata, the gem, is a moth of the family Geometridae. The species was first described by Johan Christian Fabricius in 1794. It is a cosmopolitan species. In continental Europe though in the northeast, its range does not significantly extend beyond the Baltic region and it is absent from northern Russia. This well-flying species is prone to vagrancy and able to cross considerable distances of the open sea; it can thus be regularly found on the British Isles and even on Iceland.

<i>Galleria mellonella</i> Species of moth

Galleria mellonella, the greater wax moth or honeycomb moth, is a moth of the family Pyralidae. G. mellonella is found throughout the world. It is one of two species of wax moths, with the other being the lesser wax moth. G. mellonella eggs are laid in the spring, and they have four life stages. Males are able to generate ultrasonic sound pulses, which, along with pheromones, are used in mating. The larvae of G. mellonella are also often used as a model organism in research.

Enarmonia formosana, the cherrybark tortrix or cherry-bark moth, is a small but colorful moth species of the family Tortricidae. It is native to all of northern and western Europe, ranging south to the Maghreb. North of the Alps its range extends eastwards to Siberia and Kazakhstan. Possibly and most likely introduced populations are found in Asia Minor and North America, respectively.

Batia lunaris, the lesser tawny crescent, is a species of gelechioid moth. It belongs to the subfamily Oecophorinae of the concealer moth family (Oecophoridae). It is the type species of the genus Batia, which is sometimes treated as monotypic. But this is not well warranted, as some other species usually placed there differ little from the Lesser Tawny Crescent.

<i>Nemapogon cloacella</i> Species of moth

Nemapogon cloacella, the cork moth, is a species of tineoid moth. It belongs to the fungus moth family (Tineidae), and therein to the subfamily Nemapogoninae. Its junior synonym N. infimella was established by G.H. Heydenreich in the 1851 volume of his Lepidopterorum Europaeorum Catalogus Methodicus, but many sources still attribute it to G.A.W. Herrich-Schäffer, who supposedly narrowly beat Heidenreich in (re)describing the species. But as it seems, Herrich-Schäffer was merely one of the first to use the name proposed by Heydenreich, as the volume of his Systematische Bearbeitung der Schmetterlinge von Europa where he discussed the cork moth was not published until 1853 or 1854. That all nonwithstanding, the species had been already validly described by A.H. Haworth in the 1828 volume of Lepidoptera Britannica.

<i>Cadra calidella</i> Species of moth

Cadra calidella, the dried fruit or date moth, is a species of snout moth in the genus Cadra and commonly mistaken for the species Cadra figulilella. It thrives in warmer conditions and is found primarily in Mediterranean countries, although it can also be found in Central Asia, Kazakhstan, Transcaucasia, Caucasus, and the western part of Russia. It feeds on dried fruits, carobs, nuts and seeds, hence earning its colloquial name. This diet damages the food industry, and it is a common storage pest. Because of this, much research has been done to study ways to limit its reproduction rate and population size. It was first described by Achille Guenée in 1845.
