Leaf Beetle
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, f ...

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 ...

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 ...

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.

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.

Leonard Gyllenhaal
Leonard Gyllenhaal (3 December 1752 – 13 May 1840) was a Swedish military officer and entomologist. Born on the Ribbingsberg manor in Västergötland in west Sweden, Leonard Gyllenhaal was son of an army officer and belonged to a family of the lower nobility. He went to school ( Skara trivialskola) in the cathedral town of Skara together with, among others, the future poet Johan Henrik Kellgren, and later renowned naturalists Anders Dahl and the brothers Adam and Johan Afzelius, with whom he went on natural excursions. Like some of his friends, he went to Uppsala to study under Linnaeus in 1769. He never matriculated and remained in Uppsala only one semester, before switching to a military career in accordance with the wishes and traditions of the family, enrolling in the '' Adelsfanan'' ( "Banner of Nobles") cavalry regiment, and a few years later transferring to the drabantkåren (Garde du Corps). Gyllenhaal, however, remained in contact with Linnaeus through an exte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pierre Latreille
Pierre is a masculine given name. It is a French form of the name Peter. Pierre originally meant "rock" or "stone" in French (derived from the Greek word πέτρος (''petros'') meaning "stone, rock", via Latin "petra"). It is a translation of Aramaic כיפא (''Kefa),'' the nickname Jesus gave to apostle Simon Bar-Jona, referred in English as Saint Peter Saint Peter; he, שמעון בר יונה, Šimʿōn bar Yōnāh; ar, سِمعَان بُطرُس, translit=Simʿa̅n Buṭrus; grc-gre, Πέτρος, Petros; cop, Ⲡⲉⲧⲣⲟⲥ, Petros; lat, Petrus; ar, شمعون الصفـا, Sham'un ....

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 ...

Prothorax
The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum (dorsal), the prosternum (ventral), and the propleuron (lateral) on each side. The prothorax never bears wings in extant insects (except in some cases of atavism), though some fossil groups possessed wing-like projections. All adult insects possess legs on the prothorax, though in a few groups (e.g., the butterfly family Nymphalidae) the forelegs are greatly reduced. In many groups of insects, the pronotum is reduced in size, but in a few it is hypertrophied, such as in all beetles (Coleoptera). In most treehoppers (family Membracidae, order Hemiptera), the pronotum is expanded into often fantastic shapes that enhance their camouflage or mimicry. Similarly, in the Tetrigidae, the pronotum is extended backward to cover the flight wings, supplanting the function of the tegmina. See also *Glossary of entomolo ...

Imago
In biology, the imago (Latin for "image") is the last stage an insect attains during its metamorphosis, its process of growth and development; it is also called the imaginal stage, the stage in which the insect attains maturity. It follows the final ecdysis of the immature instars.Carpenter, Geo. H., The Life-Story of Insects. Cambridge University Press 1913. May be downloaded from: https://www.gutenberg.org/ebooks/16410 or https://archive.org/details/thelifestoryofin16410gut In a member of the Ametabola or Hemimetabola, in which metamorphosis is "incomplete", the final ecdysis follows the last immature or '' nymphal'' stage. In members of the Holometabola, in which there is a pupal stage, the final ecdysis follows emergence from the pupa, after which the metamorphosis is complete, although there is a prolonged period of maturation in some species. The imago is the only stage during which the insect is sexually mature and, if it is a winged species, has functional wings. The i ...

Insect Collecting
Insect collecting refers to the collection of insects and other arthropods for scientific study or as a hobby. Most insects are small and the majority cannot be identified without the examination of minute morphological characters, so entomologists often make and maintain insect collections. Very large collections are conserved in natural history museums or universities where they are maintained and studied by specialists. Many college courses require students to form small collections. There are also amateur entomologists and collectors who keep collections. Historically, insect collecting has been widespread and was in the Victorian age a very popular educational hobby. Insect collecting has left traces in European cultural history, literature and songs (e.g., Georges Brassens's ''La chasse aux papillons'' (''The Hunt for Butterflies'')). The practice is particularly common among Japanese youths. Collecting techniques Insects are passively caught using funnels, pitfall tra ...
