The Colorado potato beetle, also known as the Colorado beetle, the ten-striped spearman, the ten-lined potato beetle, or the potato bug, is a major pest of potato crops. It is about 10 mm long, with a bright yellow/orange body and five bold brown stripes along the length of each of its elytra. Native to the Rocky Mountains, it spread rapidly in potato crops across America and then Europe from 1859 onwards.
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 Tansy beetle is a species of leaf beetle. The common name derives from its main foodplant, Tansy, but it can also use other wetland plants such as Gypsywort and Water Mint. It measures 7.7–10.5 mm in length and has a characteristic bright metallic green colouration, with pitted elytra and a coppery tinge. In addition to the nominotypical subspecies, which repeats the specific name, C. graminis graminis, there are five further distinct subspecies of Tansy beetle, which, collectively, have a Palearctic distribution, although in the majority of countries where it is found the species is declining. In the United Kingdom it is designated as 'Nationally Rare'. The stronghold population here is located along the banks of the river Ouse in York, North Yorkshire. Other, small, fenland populations exist at Woodwalton Fen and at Welney Wildfowl and Wetlands Trust (WWT) reserve.
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 Cassidinae are a subfamily of the leaf beetles, or Chrysomelidae. The antennae arise close to each other and some members have the pronotal and elytral edges extended to the side and covering the legs so as to give them the common name of tortoise beetles. Some members, such as in the tribe Hispini, are notable for the spiny outgrowths to the pronotum and elytra.
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.
Gastrophysa viridula, known as the green dock beetle, green dock leaf beetle or green sorrel beetle, is a species of beetle native to Europe.
Chrysomela populi is a species of broad-shouldered leaf beetle belonging to the family Chrysomelidae, subfamily Chrysomelinae.
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.
Paropsides is a genus of beetles commonly called leaf beetles and in the subfamily Chrysomelinae. They are distributed from eastern Asia to eastern Australia. Paropsides are small and specialist feeders on native Australian plants. There are 21 species in Australia and they occur mainly on the south-eastern states. The green Paropsides calypso is a native species which commonly attacks the lillipilli genus Syzygium. Paropsides opposita feeds on Tea tree Melaleuca sp.
Phratora laticollis is a species of leaf beetle found in Europe and Asia. This beetle is found on Populus species and the chemistry and production of its larval defensive secretions and host plant relationships have been studied extensively.
Leptinotarsa peninsularis is a species of leaf beetle in the family Chrysomelidae. It is found in Central America and North America.
Leptinotarsa rubiginosa, the reddish potato beetle, is a species of leaf beetle in the family Chrysomelidae. It is found in Central America and North America.
Phratora purpurea, the aspen skeletonizer, is a species of leaf beetle in the family Chrysomelidae. It is found across North America, including Maryland, New York, Ontario, British Columbia, and the Northwest Territories. It feeds on willows and poplars, and is deep purple or coppery red in color.
Lamprolina is an Australian genus of leaf beetles (Chrysomelidae) found in Victoria, New South Wales, and Queensland.
Parasyrphus melanderi is a flower fly that is best known as a larval predator on the leaf beetle Chrysomela aeneicollis in the Sierra Nevada range of California.
Phratora tibialis is a species of leaf beetle found in Europe and parts of Asia. This beetle is found on willows and the chemistry and production of its larval defensive secretions and host plant relationships have been studied extensively.
Phola is a genus of leaf beetles in the family Chrysomelidae, subfamily Chrysomelinae. It occurs in east and south-east Asia, the south-west pacific, eastern and northern Australia. It was formerly a synonym of Chalcolampra. It is distinguished from other chrysomeline genera in Australia by the twisted epipleura, but its recognition may render either Chalcolampra or Phyllocharis paraphyletic.
Calomela bartoni is a beetle in the Chrysomelidae family, which is found in New South Wales and Victoria.
Doryphora is a genus of leaf beetles in the family Chrysomelidae. It includes nine species from Central and South America.
