The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 species in more than 2,500 genera, making up one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research.
Alnus glutinosa, the common alder, black alder, European alder, European black alder, or just alder, is a species of tree in the family Betulaceae, native to most of Europe, southwest Asia and northern Africa. It thrives in wet locations where its association with the bacterium Frankia alni enables it to grow in poor quality soils. It is a medium-sized, short-lived tree growing to a height of up to 30 metres (98 feet). It has short-stalked rounded leaves and separate male and female flowers in the form of catkins. The small, rounded fruits are cone-like and the seeds are dispersed by wind and water.
The flea beetle is a small, jumping beetle of the leaf beetle family (Chrysomelidae), that makes up the tribe Alticini which is part of the subfamily Galerucinae. Historically the flea beetles were classified as their own subfamily.
Acalymma is a genus of leaf beetles found mainly in the New World. Approximately 72 species have been described in the Western Hemisphere.
Neochlamisus is a genus of leaf beetles in the tribe Fulcidacini. They are members of the case-bearing leaf beetle group, the Camptosomata. Measuring 3–4 millimeters in length as adults, they are cryptic, superficially resembling caterpillar frass. Seventeen, sometimes 18 species are presently accepted in this genus, all of them occurring in North America.
The Megalopodidae are a small family of leaf beetles, previously included as a subfamily within the Chrysomelidae. One of its constituent subfamilies, Zeugophorinae, has also frequently been treated as a subfamily within Chrysomelidae. The family contains approximately 30 genera worldwide, primarily in the nominate subfamily Megalopodinae, and mostly circumtropical.
Chrysomela populi is a species of broad-shouldered leaf beetle belonging to the family Chrysomelidae, subfamily Chrysomelinae.
Parasyrphus nigritarsis is a species of hoverfly, from the family Syrphidae, in the order Diptera. It is known from northern Europe and North America, and has been considered to be a rare species in parts of its range. Adults visit flowers as a source of nutrition, and females lay their eggs on clutches of eggs of leaf beetles. When the Parasyrphus larvae hatch, they first consume leaf beetle eggs and then consume immature beetles until they reach the pupal stage. This species is related to hoverflies that prey on aphids as larvae, and has been investigated in studies of chemical ecology and food web ecology.
Menippus is a genus of leaf beetles (Chrysomelidae).
Galerucella is a genus of leaf beetles in the family Chrysomelidae described by George Robert Crotch in 1873. It is widely distributed but absent in the Neotropics. Some species feed on waterlilies and are used as biocontrol of introduced, invasive waterlilies. Galerucella tenella feed on strawberry plants.
Xanthogaleruca is a genus of beetles belonging to the family Chrysomelidae. These elm leaf beetles are pests that feed on ornamental plants until they are stripped of their leaves entirely.
Pyrrhalta is a genus of beetles in the leaf beetle family, Chrysomelidae. Species are distributed throughout much of the world, including much of the Northern Hemisphere and the Australian region.
Phratora vitellinae, the brassy leaf beetle, formerly Phyllodecta vitellinae, is a beetle of the family Chrysomelidae found in Europe and Asia. It feeds on Populus and Salix species. The evolution of its host plant preferences and the mechanism by which it uses host plant chemicals to make a larval defensive secretion have been the subject of intense study by research groups in Europe and the Nordic countries.
Chrysolina coerulans, also known as the blue mint beetle or blue mint leaf beetle, is a species of beetle in the family Chrysomelidae. It is a member of the subgenus Synerga of the genus Chrysolina. It is native to a wide range of countries between mid and eastern Europe and lives alongside rivers and in meadows, it feeds on various plant members of the mint family.
Luperus flavipes is a species of skeletonizing leaf beetle belonging to the family Chrysomelidae, subfamily Galerucinae.
Mantura floridana is a species of flea beetle in the family Chrysomelidae. It is found in North America. Larvae feed on Fallopia scandens. They appear yellow through the leaf epidermis, as the larvae are leaf miners.
Phyllotreta chalybeipennis is a species of flea beetle in the family Chrysomelidae. It is found in the Caribbean Sea and North America. Larvae are leaf miners of Cakile edentula, and adults feed on leaves of the same host.
Trirhabda flavolimbata, also called the coyote brush leaf beetle, is a species of skeletonizing leaf beetle in the family Chrysomelidae. It is found in California in coastal scrublands or chaparral habitats. Its main host plant is coyote brush, but it has been noted to feed on other species of Baccharis, as well as Aster, Senecio, Artemisia, Solidago, and Eriodictyon.
Calligrapha alni, the russet alder leaf beetle, is a species of leaf beetle in the family Chrysomelidae. It is found in North America.
Luperus viridipennis is a species of skeletonizing leaf beetle belonging to the family Chrysomelidae, subfamily Galerucinae.
