Attagenus schaefferi ye una especie de coleópteru de la familia Dermestidae.
The black carpet beetle (Attagenus unicolor) is a 3–5-millimetre-long (0.12–0.20 in) beetle that can be a serious household pest. The larvae grow to 7 mm (0.28 in) in length, are reddish brown in colour and covered with bristles. The larval form feeds on natural fibres, damaging carpets, furniture and clothing.
Attagenus unicolor undergoes complete metamorphosis, which has four life stages: Egg, larvae, pupae and adult. Each stage looks different, and needs different amounts of time to reach the next stage.
Eggs are usually laid near or on a food source. If no food source can be found, the female will lay them in dark undisturbed locations where the larvae can feed on carpeting or clothing. They will also lay eggs on or near dog food or other pet food. Eggs take anywhere from 5 to 20 days to hatch depending on the conditions, such as temperature and humidity.
Larvae are about 1 mm (0.039 in) in size when they hatch from the egg. They grow fairly quickly depending on the food source availability and protein found in the food itself. Larvae moult about 10 to 15 times, or more depending on conditions. Sometimes if food is scarce they will retro-moult with the larvae moulting into a lower instar. They can do this multiple times, if they are large enough.
The larval stage is the longest and most destructive stage; they can remain as larvae for up to 3 years, although it does not typically take longer than 3 months to go through the larval stage if food and conditions are good. Larvae pupate in undisturbed locations, far away from the food source so that they aren't cannibalized.
Pupae are cream white but quickly turn yellow and darken with age. They do not eat in this stage nor move. They transform into the beetles in about 8 to 20 days, depending on the conditions. The beetle may stay in the shedded pupae case for an additional day or two.
Beetles start out white but darken with age. They typically do not eat, although they will sometimes eat flower pollen in the wild, but not indoors. Adults live for a few weeks, just long enough to mate and lay more eggs. They are eventually black in colour, hence the name Black Carpet Beetle. Females are capable of laying 50 to 100 eggs.
The whole life cycle under ideal conditions takes about 4 to 5 months, or less if given protein-rich food, such as pet food. The adult females will lay more eggs if water is present in small amounts.

Attagenus unicolor es una especie de coleóptero de la familia Dermestidae.
Mide 2.5–5.5 mm. Se alimenta de material animal y cereales. Los adultos comen polen. Se los encuentra en nidos de aves y roedores, en lugares de almacenaje de alimentos. Originarios del Paleártico (pero no de Europa), ahora están distribuidos por todo el mundo, excepto los polos. En Norteamérica es considerado una de las peores plagas de productos almacenados, también atacan ejemplares de museo.[1][2][3][4]

Attagenus unicolor, l'attagène des tapis, est une espèce d'insectes coléoptères de la famille des Dermestidae. Cet insecte, à répartition cosmopolite, de 3 à 5 mm de long, est un ravageur domestique, qui peut être une menace sérieuse également pour les denrées stockées. La larve, de couleur brun rougeâtre et couverte de poils, peut atteindre 7 mm de long. C'est la forme larvaire qui cause le plus de dégâts. Elle se nourrit de fibres naturelles d'origine végétale ou animale, et peut endommager les tapis, les meubles et les vêtements.
Selon BioLib (5 juin 2021)[2] :
Attagenus unicolor a une aire de répartition cosmopolite[3]. Cet insecte aurait été importé aux États-Unis en provenance d'Europe au début du xixe siècle[4].

Синонимы ПодвидыКовровый кожеед, или ковровый жук (лат. Attagenus unicolor) — вид жесткокрылых насекомых из подсемейства Dermestinae внутри семейства кожеедов (Dermestidae). Распространён в Европе, Азии, а также Канаде, США, Мексике[1][2] и Австралии[3]. Подвид A. u. japonicus распространён в Хабаровском и Приморском краях, в Амурской области, Японии, Корейском полуострове, северо-восточном Китае и Монголии[4].
В природных условиях встречается заселяя гнёзда птиц, живущих в дуплах деревьев.
Тело жука овальное длиной 2,5—5,5 мм. Окрас равномерный от светло-коричневого до чёрного. Ковровый кожеед — довольно распространённый синантропный вид кожеедов. Живёт в том числе в домах, питаясь органическими остатками в домашней пыли.
Является серьёзным вредителем кожи, меха и шерсти, а также изделий из них. Также может повреждать перья, шёлк, зерно, муку и другие растительные продукты. Вред наносят только личинки.
