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.
The Donaciinae are a subfamily of the leaf beetles, or Chrysomelidae, characterised by distinctly long antennae. They are found in mainly the Northern Hemisphere, with some species found in the Southern Hemisphere.
Cassida is a large Old World genus of tortoise beetles in the subfamily Cassidinae. The natural history of Cassida sphaerula in South Africa is a typical life cycle. Several species of Cassida are important agricultural pests, in particular C. vittata and C. nebulosa on sugar beet and spinach. The thistle tortoise beetle has been used as a biological control agent against Canada thistle.
Syneta is a genus of leaf beetles in the subfamily Synetinae. There are about 11 described species in Syneta. The genus is entirely holarctic in distribution, with species appearing in North America, Siberia, East Asia and Northern Europe.
Phratora is a genus of leaf beetles. It is synonymous to Phyllodecta . European Phratora species can be distinguished based on morphology of female genitalia., but they differ little in size and body form and most show metallic coloration.
Artipus floridanus, the little leaf notcher, is a species of broad-nosed weevil in the beetle family Curculionidae. It is found in North America.
Cryptocephalus downiei, or Downie's spotted leaf beetle, is a species of case-bearing leaf beetle in the family Chrysomelidae. It is found in North America. The specific epithet downiei honors American psychologist and coleopterist Norville Downie.
Chrysomela crotchi, the aspen leaf beetle, is a species of leaf beetle in the family Chrysomelidae. It is found in North America.
Phaedon desotonis, known generally as the desoto leaf beetle or coreopsis leaf beetle, is a species of leaf beetle in the family Chrysomelidae. It is found in North America.
Lygistus is a genus of leaf beetles in the family Chrysomelidae. There is one described species in Lygistus, Lygistus streptophallus.
Oomorphus is a genus of leaf beetles in the family Chrysomelidae. There are about 18 described species in Oomorphus.
Chrysomela sonorae is a species of leaf beetle in the family Chrysomelidae. It is found in Central America and North America.
Cryptocephalus defectus is a species of case-bearing leaf beetle in the family Chrysomelidae. It is found in North America.
Charidotella is a genus of tortoise beetles in the family Chrysomelidae. There are at least 100 described species in Charidotella.
Cryptocephalus binotatus is a species of case-bearing leaf beetle in the family Chrysomelidae. It is found in North America.
Brachypnoea clypealis is a species of leaf beetle. It is found in the Eastern United States.
Cadiz is a genus of leaf beetles in the subfamily Chrysomelinae, found in North America. It contains only one species, Cadiz hardyi, which was described from the Cadiz Dunes in San Bernardino County, California.
Phratora hudsonia, the birch leaf beetle, is a species of leaf beetle in the family Chrysomelidae. It is found in North America. This species is known from Canadian populations at the Great Slave Lake and north shore of Lake Superior. It feeds on birch and is metallic brown in color. It is relatively small in size, like other Phratora species.
Coleothorpa dominicana is a species of case-bearing leaf beetle in the family Chrysomelidae. It is found in North America. These case-bearing leaf beetles lay eggs and the female beetle constructs a funnel structure that helps protect the eggs. The larvae lasts for 5 to 8 months and it takes about one year to fully develop the beetles to adulthood.
Brachypnoea puncticollis, the rose leaf beetle, is a species of leaf beetle. It is distributed from the Eastern United States to the Rocky Mountains.
