Chrysomelidae
The insects of the beetle family Chrysomelidae are commonly known as leaf beetles, and include over 37,000 (and probably at least 50,000) 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. Leaf beetles are partially recognizable by their tarsal formula, which appears to be 4-4-4, but is actually 5-5-5 as the fourth tarsal segment is very small and hidden by the third. As with many taxa, no single character defines the Chrysomelidae; instead, the family is delineated by a set of characters. Some lineages are only distinguished with difficulty from longhorn beetles (family Cerambycidae), namely by the antennae not arising from frontal tubercles. Adult and larval leaf beetles feed on all sorts of plant tissue, and all species are fully herbivorous. Many are serious pests of cultivated plants, ...

Cereal Leaf Beetle
The cereal leaf beetle (''Oulema melanopus'') is a significant crop pest, described by Carl Linnaeus in 1758. Life history One generation of this beetle is produced a year. Adults feed before winter and spend most of their overwintering time in protected areas such as wind rows, crop stubble, and tree bark crevices. Adults mate once the temperature warms to above 9–10 degrees Celsius (or 44.6 degrees F) and females have a relatively long laying period (about 45–60 days), when they deposit eggs on the undersides of leaves. The larvae hatch in 7–15 days, and start the most damaging eating of the entire lifecycle. These larvae mature in 12–20 days. Larvae are the greatest threat to crops, as they eat the superficial layer of leaves, hindering the leaves' photosynthetic potential. According to Kon, Zabik, Webster, and Leavitt, a chemical factor attracts the beetles to leaves, and that chemical factor is directly related to hydrophobicity. Pupation occurs in soil, with the adu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colorado Potato Beetle
The Colorado potato beetle (''Leptinotarsa decemlineata''), 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 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. Taxonomy The Colorado potato beetle was first observed in 1811 by Thomas Nuttall and was formally described in 1824 by American entomologist Thomas Say.see pp. 453–454: "Doryphora, Illig.: D. 10-lineata"./ref> The beetles were collected in the Rocky Mountains, where they were feeding on the buffalo bur, '' Solanum rostratum''. The genus ''Leptinotarsa'' is assigned to the chrysolmelid beetle tribe Chrysomelini (in subfamily Chrysomelinae). Description Adult beetles typically are in length and in width. They weigh 50-170 mg. The beetles ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donaciinae
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. Life cycle Female Donaciinae lay eggs between aquatic plant stems and leaf sheaths. When larvae hatch they are aquatic, and attach themselves to underwater stems and roots of their plant hosts, primarily '' Potamogeton'', for food and oxygen. Adults live in vegetation bordering ponds, marshes, lakes, and brackish water environments. While most Donaciinae have the ability to fly, fully aquatic and flightless species such as '' Macroplea mutica'' exhibit the ability to disperse long distance by surviving the passage though the gut of water birds. Genera These six genera belong to the subfamily Donaciinae: * '' Donacia'' Fabricius, 1775 * '' Donaciella'' Reitter, 1920 * '' Macroplea'' Samouelle, 1819 * '' Neohaemonia'' Székessy, 1941 * '' Plateumaris'' Thomson, 1859 ...

Chrysomelinae
The Chrysomelinae are a subfamily of leaf beetles (Chrysomelidae), commonly known as broad-bodied leaf beetles or broad-shouldered leaf beetles. It includes some 3,000 species around the world. The best-known member is the notorious Colorado potato beetle (''Leptinotarsa decemlineata''), an important agricultural pest. Description Adults of Chrysomelinae are beetles with the following features: antennae inserted on or adjacent to anterior edge of head; inner face of each mandible with large membranous prostheca; each wing with only one anal cell (sometimes the wings are reduced or absent); metendosternite lateral arms without lobes; femora without internal spring sclerite; tibial spurs absent; tarsi without bifid setae; stridulatory mechanism absent; male aedeagus without tegminal ring and the testes not fused within a common membrane; female kotpresse absent.

Cassidinae
The Cassidinae (tortoise and leaf-mining beetles) 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. Description The "cassidoids" have a rounded outline with the edges of the pronotum and elytra expanded, spreading out to cover the legs and head. They are often colourful and metallic, with ornate sculpturing; a few species have the ability to change the colour due to water movements within the translucent cuticle. All members of the subfamily have the mouthparts reduced into a cavity in the head capsule, the legs have four segmented tarsi. The hispoids have larvae that are leaf miners, while the cassidoids feed on the plant surfaces, sometimes covering their bodies with faecal shi ...

Asparagus Beetle
''Crioceris'', or asparagus beetle, is a genus of the family Chrysomelidae of beetles. The name is neo-Latin from Greek , ram and , horn. Not all species in the genus ''Crioceris'' feed on asparagus (e.g., ''C. nigropicta''). Some studies have found low genetic diversity among groups of isolated Chrysomelidae, and use ''Wolbachia'' species as a genetic marker. Species *'' Crioceris asparagi'' (Linnaeus, 1758), common asparagus beetle *'' Crioceris bicruciata'' ( Sahlberg, 1823) *'' Crioceris duodecimpunctata'' (Linnaeus, 1758), spotted asparagus beetle *'' Crioceris macilenta'' Weise, 1880 *'' Crioceris nigropunctata'' Lacordaire, 1845 *'' Crioceris paracenthesis'' (Linnaeus, 1767) *'' Crioceris quatuordecimpunctata'' (Scopoli, 1763) *'' Crioceris quinquepunctata'' (Scopoli Giovanni Antonio Scopoli (sometimes Latinized as Johannes Antonius Scopolius) (3 June 1723 – 8 May 1788) was an Italian physician and naturalist.

Lilioceris Lilii
''Lilioceris'' is a genus of beetles in the leaf beetle family, Chrysomelidae. The genus was first scientifically described in 1912 by Edmund Reitter. ''Lilioceris'' belongs to the subfamily Criocerinae and tribe Criocerini (Latreille, 1807). The family of beetles are of importance in horticulture because of their impact on the cultivation of lilies. ''Lilioceris cheni'' was introduced into Central Florida by biologists to try to control the spread of invasive air potato plants. Description Species of ''Lilioceris'' are between 4 and 10 mm long. The body has a long narrow shape, with a pronounced shoulder between the elytra and pronotum. Both the larvae and the adult (imago) beetles feed on plants. Lifecycle ''Lilioceris'' species are holometabolism, holometabolous, having a complete metamorphosis. The larvae proceed to a pupation stage to develop into adults. Diversity Well over 100 species are described, with 80 in Asia alone.Tishechkin, A. K., et al. (2011)Review of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flea Beetle
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. Though most tribes of the Galerucinae are suspect of rampant paraphyly in the present delimitation, the Alticini seem to form a good clade. Description and ecology The adults are very small to moderately sized Chrysomelidae (i.e. among beetles in general they are on the smallish side). They are similar to other leaf beetles, but characteristically have the hindleg femora greatly enlarged. These enlarged femora allow for the springing action of these insects when disturbed. Flea beetles can also walk normally and fly. Many flea beetles are attractively colored; dark, shiny and often metallic colors predominate. Adult flea beetles feed externally on plants, eating the surface of the leaves, stems and petals. Under heavy feeding the small round h ...

Cryptocephalinae
The Cryptocephalinae are a subfamily of the leaf beetles (Chrysomelidae), and belong to the group of case-bearing leaf beetles called the Camptosomata. The tribes Fulcidacini and Clytrini The Clytrini are a tribe within the leaf beetle subfamily Cryptocephalinae, though historically they were often treated as a distinct subfamily, Clytrinae. As the other Cryptocephalinae, they belong to the group of case-bearing leaf beetles know ... were formerly considered subfamilies of their own, and are presently treated only as tribes. Species in at least 14 genera of Clytrini and Cryptocephalini are myrmecophilous, living with ants.Agrain F.A., M. Buffington, C.S. Chaboo, M.L. Chamorro, & M.E. Schöller. 2015.

Bruchinae
The bean weevils or seed beetles are a subfamily (Bruchinae) of beetles, now placed in the family Chrysomelidae, though they have historically been treated as a separate family. They are granivores, and typically infest various kinds of seeds or beans, living most of their lives inside a single seed. The subfamily includes about 1,650 species and are found worldwide. Bean weevils are generally compact and oval in shape, with small heads somewhat bent under. Sizes range from 1 to 22 mm for some tropical species. Colors are usually black or brown, often with mottled patterns. Although their mandibles may be elongated, they do not have the long snouts characteristic of true weevils. Adults deposit eggs on seeds, then the larvae chew their way into the seed. When ready to pupate, the larvae typically cut an exit hole, then return to their feeding chamber. Adult weevils have a habit of feigning death and dropping from a plant when disturbed. Host plants tend to be legumes, but ...
