Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts. They are usually small – less than 6 mm in length – and herbivorous. Approximately 97,000 species of weevils are known. They belong to several families, with most of them in the family Curculionidae. It also includes bark beetles, which while morphologically dissimilar to other weevils in lacking the distinctive snout, is a subfamily of Curculionidae. Some other beetles, although not closely related, bear the name "weevil", such as the biscuit weevil, which belongs to the family Ptinidae.
The longhorn beetles (Cerambycidae), also known as long-horned or longicorns, are a large family of beetles, with over 35,000 species described.
Dermestidae are a family of Coleoptera that are commonly referred to as skin beetles. Other common names include larder beetle, hide or leather beetles, carpet beetles, and khapra beetles. There are over 1,800 species described.
The khapra beetle, also called cabinet beetle, which originated in South Asia, is one of the world's most destructive pests of grain products and seeds. It is considered one of the 100 worst invasive species in the world. Infestations are difficult to control because of the insect's ability to survive without food for long periods, its preference for dry conditions and low-moisture food, and its resistance to many insecticides. There is a federal quarantine restricting the importation of rice into the U.S. from countries with known infestations of the beetle. Khapra beetle infestation can spoil otherwise valuable trade goods and threaten significant economic losses if introduced to a new area. Handling or consuming contaminated grain and seed products can lead to health issues such as skin irritation and gastrointestinal distress.
Tenebrioninae is the largest subfamily of the darkling beetles (Tenebrionidae), containing flour beetles, among others. Tenebrioninae contains more than 20 tribes.
Trogoderma is a genus of beetles in the family Dermestidae, the skin beetles. There are about 135 species worldwide.
Megatominae is a subfamily of the beetle family Dermestidae. This subfamily contains several of the most well-known household and stored-product pest beetles, in the genera Anthrenus and Trogoderma.
Ctesias is a genus of beetles in the family Dermestidae, the skin beetles. They are distributed in the Palearctic, including Europe. There are about 23 species.
The Ommatidae are a family of beetles in the suborder Archostemata. The Ommatidae are considered the extant beetle family that has most ancestral characteristics. There are only seven extant species, confined to Australia and South America. However, the geographical distribution was much wider during the Mesozoic spanning across Eurasia and Australia, suggesting that they were widespread on Pangea. So far, over 26 extinct genera containing over 170 species of these beetles have been described. Three extant genera have been assigned to this family: Omma,Tetraphalerus and Beutelius. The family is considered to be a subfamily of Cupedidae by some authors, but have been found to be more closely related to Micromalthidae in molecular phylogenies. A close relationship with Micromalthidae is supported by several morphological characters, including those of the mandibles and male genitalia. Due to their rarity, their ecology is obscure, it is likely that their larvae feed on deadwood.
Anthrenocerus australis is a species of beetle belonging to the Dermestidae family. It is commonly known as the Australian carpet beetle and is one of the most researched of the thirty-one species in the Anthrenocerus genus. This is generally attributed to its prevalence throughout Australia and New Zealand and the negative economic and agricultural impact it has as a pest. It is the larvae that causes damage to products, not the adult beetle. The total life cycle of this insect is around three years, most of which is spent as a larva. Once the beetle reaches maturity, it only lives for between two and six weeks.
Anthrenus flavipes is a species of beetle in the family Dermestidae known by the common name furniture carpet beetle. It has a cosmopolitan distribution, occurring throughout the world, being most active in warmer climates. It is a pest that damages household materials such as textiles.
Dermestes ater is a species of beetle in the family Dermestidae, the skin beetles. It is known commonly as the black larder beetle or incinerator beetle. It is native to North America, but today it is found nearly worldwide. Like several other dermestid beetles, this species is a common pest of stored products.
Trogoderma inclusum, the larger cabinet beetle, is a species of carpet beetle in the family Dermestidae. It is found in Africa, Europe and Northern Asia, North America, Oceania, and Southern Asia.
Trogoderma glabrum, known generally as the glabrous cabinet beetle or colored cabinet beetle, is a species of carpet beetle in the family Dermestidae. It is found in Europe and Northern Asia and North America.
Dearthrus is a genus of carpet beetles in the family Dermestidae local to North America. There are at least two described species in Dearthrus.
Trogoderma primum is a species of carpet beetle in the family Dermestidae. It is found in North America, where it is known from Oklahoma and Texas in the United States, and from Veracruz and Chiapas in Mexico.
The Megatomini are a tribe of insects in the family Dermestidae.
Nathrenus is a subgenus of the genus Anthrenus of the subfamily Megatominae within the family of skin beetles. The most well-known species from the subgenus, varied carpet beetle, is distributed in most parts of the world, whereas the vast majority of other species are only present in regions of Africa and Asia.
Trogoderma angustum is a species of beetle in the family Dermestidae native to South America. It has been introduced to several regions including Europe, Asia, United States, New Zealand, and possibly Congo.
Eurhopalus is a genus of beetles in the family Dermestidae. The genus was revised in 2022 to include several genera, along with species previously placed in the genus Trogoderma.
