Milkweed Leaf Beetle
The milkweed leaf beetle (''Labidomera clivicollis'') is a species of beetle from the family Chrysomelidae. Description ''L. clivicollis'' is a small, rounded beetle 8–11 mm in length. It has a black head and pronotum, but brightly coloured elytra; variable from dark orange to bright yellow. The elytra are mottled with black patches throughout. The larva of ''L. clivicollis'' is bright orange, with a prominent row of black spiracles. Diet There are a number of host plants associated with ''L. clivicollis'': milkweeds, especially swamp milkweed (''Asclepias incarnata'') and common milkweed ('' A. syriaca''); swallow-wort ('' Cynanchum''); twinevine (''Funastrum ''Funastrum'' is a genus of flowering plant now in the family Apocynaceae.

William Kirby (entomologist)
William Kirby (19 September 1759 – 4 July 1850) was an English entomologist, an original member of the Linnean Society and a Fellow of the Royal Society, as well as a country rector, so that he was an eminent example of the "parson-naturalist". The four-volume ''Introduction to Entomology'', co-written with William Spence, was widely influential. Family origins and early studies Kirby was a grandson of the Suffolk topographer John Kirby (author of ''The Suffolk Traveller'') and nephew of artist-topographer Joshua Kirby (a friend of Thomas Gainsborough's). He was also a cousin of the children's author Sarah Trimmer. His parents were William Kirby, a solicitor, and Lucy Meadows. He was born on 19 September 1759 at Witnesham, Suffolk, and studied at Ipswich School and Caius College, Cambridge, where he graduated in 1781. Taking holy orders in 1782, he spent his entire working life in the peaceful seclusion of an English country parsonage at Barham in Suffolk, working at th ...

Beetle
Beetles are insects that form the order Coleoptera (), in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 described species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently, with estimates suggesting that there are between 0.9 and 2.1 million total species. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae (ladybirds or ladybugs) eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops. Beetles typically have a particularly hard e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ...

Integrated Taxonomic Information System
The Integrated Taxonomic Information System (ITIS) is an American partnership of federal agencies designed to provide consistent and reliable information on the taxonomy of biological species. ITIS was originally formed in 1996 as an interagency group within the US federal government, involving several US federal agencies, and has now become an international body, with Canadian and Mexican government agencies participating. The database draws from a large community of taxonomic experts. Primary content staff are housed at the Smithsonian National Museum of Natural History and IT services are provided by a US Geological Survey facility in Denver. The primary focus of ITIS is North American species, but many biological groups exist worldwide and ITIS collaborates with other agencies to increase its global coverage. Reference database ITIS provides an automated reference database of scientific and common names for species. As of May 2016, it contains over 839,000 scientific names, ...

Pronotum
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 ...

Elytron
An elytron (; ; , ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs (Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometimes alternatively spelled as "hemielytra"), and in most species only the basal half is thickened while the apex is membranous, but when they are entirely thickened the condition is referred to as "coleopteroid". An elytron is sometimes also referred to as a shard. Description The elytra primarily serve as protective wing-cases for the hindwings underneath, which are used for flying. To fly, a beetle typically opens the elytra and then extends the hindwings, flying while still holding the elytra open, though many beetles in the families Scarabaeidae and Buprestidae can fly with the elytra closed (e.g., most Cetoniinae; ). In a number of groups, the elytra are reduced to various degrees, (e.g., the beetle families Staphylinidae and Ripiphoridae), o ...

Spiracle (arthropods)
A spiracle or stigma is the opening in the exoskeletons of insects and some spiders to allow air to enter the trachea. In the respiratory system of insects, the tracheal tubes primarily deliver oxygen directly into the animals' tissues. The spiracles can be opened and closed in an efficient manner to reduce water loss. This is done by contracting closer muscles surrounding the spiracle. In order to open, the muscle relaxes. The closer muscle is controlled by the central nervous system, but can also react to localized chemical stimuli. Several aquatic insects have similar or alternative closing methods to prevent water from entering the trachea. The timing and duration of spiracle closures can affect the respiratory rates of the organism. Spiracles may also be surrounded by hairs to minimize bulk air movement around the opening, and thus minimize water loss. Although all insects have spiracles, only some spiders have them, such as orb weavers and wolf spiders. Ancestrally, spiders ...

Asclepias Incarnata
''Asclepias incarnata'', the swamp milkweed, rose milkweed, rose milkflower, swamp silkweed, or white Indian hemp, is a herbaceous perennial plant species native to North America. It grows in damp through wet soils and also is cultivated as a garden plant for its flowers, which attract butterflies and other pollinators with nectar. Like most other milkweeds, it has latex containing toxic chemicals, a characteristic that repels insects and other herbivorous animals. Description Swamp milkweed is an upright, tall plant, growing from thick, fleshy, white roots. Typically, its stems are branched and the clump forming plants emerge in late spring after most other plants have begun growth for the year. The oppositely arranged leaves are long and wide and are narrow and lance-shaped, with the ends tapering to a sharp point. The plants bloom in early through mid-summer, producing small, fragrant, pink to mauve (sometimes white) colored flowers in rounded umbellate racemes. The flo ...

Asclepias Syriaca
''Asclepias syriaca'', commonly called common milkweed, butterfly flower, silkweed, silky swallow-wort, and Virginia silkweed, is a species of flowering plant. It is native to southern Canada and much of the United States east of the Rocky Mountains, excluding the drier parts of the prairies. It is in the genus ''Asclepias'', the milkweeds. It grows in sandy soils as well as other kinds of soils in sunny areas. Description ''A. syriaca'' is a clonal perennial plant, perennial forb growing up to tall. Individual plants grow from rhizomes. All parts of common milkweed plants produce a white latex when cut.

Cynanchum
''Cynanchum'' is a genus of about 300 species including some swallowworts, belonging to the family Apocynaceae. The taxon name comes from Greek ''kynos'' (meaning "dog") and ''anchein'' ("to choke"), hence the common name for several species is dog-strangling vine. Most species are non-succulent climbers or twiners. There is some evidence of toxicity. Morphology These plants are perennial herbs or subshrubs, often growing from rhizomes. The leaves are usually oppositely arranged and sometimes are borne on petioles. The inflorescences and flowers come in a variety of shapes. Like other species of the milkweed family, these plants bear follicles, which are podlike dry fruits. Distribution These species are found throughout the tropics and subtropics. Several species also grow in temperate regions. Importance The root of '' Cynanchum atratum'' is used in Chinese traditional medicine and called ''Bai wei''. Several other species had traditional Chinese medicinal uses. ''Cynanc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
