The Curculionidae are the family of the "true" weevils. They are one of the largest animal families, with 6,800 genera and 83,000 species described worldwide. They are the sister group to the subfamily Brentidae
A bark beetle is one of about 6,000 species in 247 genera of beetles in the subfamily Scolytinae. Previously, this was considered a distinct family (Scolytidae), but is now understood to be specialized clade of the "true weevil" family (Curculionidae). Although the term "bark beetle" refers to the fact that many species feed in the inner bark (phloem) layer of trees, the subfamily also has many species with other lifestyles, including some that bore into wood, feed in fruit and seeds, or tunnel into herbaceous plants. Well-known species are members of the type genus Scolytus, namely the European elm bark beetle S. multistriatus and the large elm bark beetle S. scolytus, which like the American elm bark beetle Hylurgopinus rufipes, transmit Dutch elm disease fungi (Ophiostoma). The mountain pine beetle Dendroctonus ponderosae, southern pine beetle Dendroctonus frontalis, and their near relatives are major pests of conifer forests in North America. A similarly aggressive species in Europe is the spruce ips Ips typographus. A tiny bark beetle, the coffee berry borer, Hypothenemus hampei is a major pest on coffee plantations around the world.
Chrysolopus spectabilis is a species of weevil found in south-eastern Australia. It was discovered during James Cook's first voyage, and became the first insect to be described from Australia. The weevil measures up to 25 mm (1.0 in) long and includes distinctive metallic green and black scales. It is found only on 28 species of the plant genus Acacia.
The coffee borer beetle or coffee berry borer is a small beetle native to Africa. It is among the most harmful pests to coffee crops across the world where coffee is cultivated. Spanish common names of the insect include barrenador del café, gorgojo del café, and broca del café.
Dendroctonus is a genus of bark beetles. It includes several species notorious for destroying trees in the forests of North America. The genus has a symbiotic relationship with many different yeasts, particularly those in the genera Candida (fungus) and Pichia that aid in digestion and pheromone production.
Laemophloeidae, "lined flat bark beetles," is a family in the superfamily Cucujoidea characterized by predominantly dorso-ventrally compressed bodies, head and pronotal discs bordered by ridges or grooves, and inverted male genitalia. Size range of adults is 1–5 mm (0.04–0.2 in) in length. Currently, it contains 40 genera and about 450 species, and is represented on all continents except Antarctica; species richness is greatest in the tropics.
Ips is a genus of beetles in the family Curculionidae, the true weevils. They are bark beetles, members of the subfamily Scolytinae. Species are distributed throughout the Northern Hemisphere. Some are known as introduced species in Australia and Africa. Many species are pests of forest trees, especially pines and spruces. They are known commonly as engraver beetles, ips engraver beetles, and pine engravers.
Scolytus schevyrewi, the banded elm bark beetle, is a 3–4 mm long elm bark beetle species in the genus Scolytus native from Asia and accidentally introduced to North America. It is a vector of the Dutch elm disease, caused by the Ascomycota Ophiostoma ulmi and Ophiostoma novo-ulmi. In North America, it is displacing both the native elm bark beetle and the previously introduced smaller European elm bark beetle, which are becoming less common in their range with the expansion of S. schevyrewi.
Metamasius callizona, or the Mexican bromeliad weevil, is in an invasive species in Florida, USA that targets several species of bromeliad. This species is native to southern Mexico, Guatemala, and Panama, and was first documented in Florida in 1989.
Scolytini is a tribe of typical bark beetles in the family Curculionidae. There are at least 50 genera and 160 described species in Scolytini.
Hypothenemus seriatus is a species of typical bark beetle in the family Curculionidae.
Hypothenemus dissimilis is a species of typical bark beetle in the family Curculionidae. It is found in North America.
Hypothenemus crudiae is a species of typical bark beetle in the family Curculionidae. It is found in North America and Europe.
Hypothenemus birmanus, the kiawe scolytid, is a species of typical bark beetle in the family Curculionidae. It is found in North America.
Xyloterinus is a genus of typical bark beetles in the family Curculionidae. This is a monotypic genus and the one described species is Xyloterinus politus. It is native to North America where it infests both hardwood and softwood trees, as well as stacks of logs.
Hypothenemus obscurus, the apple twig beetle, is a species of typical bark beetle in the family Curculionidae. It is found in North America.
Hypothenemus areccae is a species of typical bark beetle in the family Curculionidae. It is found in North America.
Hypothenemus eruditus is a species of typical bark beetle in the family Curculionidae. It is found in North America, temperate Asia, and Europe.
Cnestus mutilatus, commonly known as the camphor shot borer, camphor shoot borer, or sweetgum ambrosia beetle, is a species of ambrosia beetle in the subfamily Scolytinae of the weevil family Curculionidae. It is native to Asia, but has been established as an invasive species in the United States since 1999.
