Bidens Kiribatiensis
''Bidens'' is a genus of flowering plants in the aster family, Asteraceae.''Bidens''.
Flora of North America.
The genus include roughly 230 species which are distributed worldwide.Knope, M. L., Funk, V. A., Johnson, M. A., Wagner, W. L., Datlof, E. M., Johnson, G., ... & Carlquist, S. (2020). Dispersal and adaptive radiation of ''Bidens'' (Compositae) across the remote archipelagoes of Polynesia. ''Journal of Systematics and Evolution'', ''58''(6), 805-822. Despite their global distribution, the systematics and taxonomy of the genus has been described as complicated and unorganized.Ganders, F. R., Berbee, M., & Perseyedi, M. (2000).

Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ...

Plant Pathogen
Plant pathology (also phytopathology) is the scientific study of diseases in plants caused by pathogens (infectious organisms) and environmental conditions (physiological factors). Organisms that cause infectious disease include fungi, oomycetes, bacteria, viruses, viroids, virus-like organisms, phytoplasmas, protozoa, nematodes and parasitic plants. Not included are ectoparasites like insects, mites, vertebrate, or other pests that affect plant health by eating plant tissues. Plant pathology also involves the study of pathogen identification, disease etiology, disease cycles, economic impact, plant disease epidemiology, plant disease resistance, how plant diseases affect humans and animals, pathosystem genetics, and management of plant diseases. Overview Control of plant diseases is crucial to the reliable production of food, and it provides significant problems in agricultural use of land, water, fuel and other inputs. Plants in both natural and cultivated populat ...

Bidens Mottle Virus
''Bidens mottle virus'' (BiMoV) is a pathogenic plant virus in the plant virus family ''Potyviridae''. BiMoV is a flexuous filamentous particle, 720 nm long, and belongs to the Potyviridae genus ''Potyvirus''. Like other viruses in this genus, ''Bidens mottle virus'' is transmitted both mechanically by sap and by aphids in a stylet-borne fashion. BiMoV was first described in 1968 by Steve Christie, John Edwardson, and Bill Zettler from the Plant Pathology and Agronomy Departments at the University of Florida, Gainesville, Florida. This virus was originally isolated from a mottled plant of the common weed ''Bidens pilosa'' collected in Gainesville – hence the name ''Bidens mottle virus''. At the same time it was also found in pepperweed ('' Lepidium virginicum''). ''B. pilosa'' can be doubly infected with BiMoV and a second virus called '' Sonchus yellow net virus'' (SYNV). SYNV is asymptomatic in ''B. pilosa'' but it enhances the symptoms of BiMoV in this plant when ...

Vanessa Cardui
''Vanessa cardui'' is the most widespread of all butterfly species. It is commonly called the painted lady, or formerly in North America the cosmopolitan.

In Australia, ''V. cardui'' has a limited range around Bunbury, Fremantle, and Rottnest Island. However, its close relative, the Australian painted lady (''V. kershawi'', sometimes considered a subspecies) ranges over half the continent. Othe ...

Nymphalidae
The Nymphalidae are the largest family of butterflies, with more than 6,000 species distributed throughout most of the world. Belonging to the superfamily Papilionoidea, they are usually medium-sized to large butterflies. Most species have a reduced pair of forelegs and many hold their colourful wings flat when resting. They are also called brush-footed butterflies or four-footed butterflies, because they are known to stand on only four legs while the other two are curled up; in some species, these forelegs have a brush-like set of hairs, which gives this family its other common name. Many species are brightly coloured and include popular species such as the emperors, monarch butterfly, admirals, tortoiseshells, and fritillaries. However, the under wings are, in contrast, often dull and in some species look remarkably like dead leaves, or are much paler, producing a cryptic effect that helps the butterflies blend into their surroundings. Nomenclature Rafinesque introduced ...

Noctuidae
The Noctuidae, commonly known as owlet moths, cutworms or armyworms, are a family of moths. They are considered the most controversial family in the superfamily Noctuoidea because many of the clades are constantly changing, along with the other families of the Noctuoidea. It was considered the largest family in Lepidoptera for a long time, but after regrouping Lymantriinae, Catocalinae and Calpinae within the family Erebidae, the latter holds this title now. Currently, Noctuidae is the second largest family in Noctuoidea, with about 1,089 genera and 11,772 species. This classification is still contingent, as more changes continue to appear between Noctuidae and Erebidae. Description Adult: Most noctuid adults have drab wings, but some subfamilies, such as Acronictinae and Agaristinae, are very colorful, especially those from tropical regions (e.g. '' Baorisa hieroglyphica''). They are characterized by a structure in the metathorax called the nodular sclerite or epaulette, whic ...

Lepidoptera
Lepidoptera ( ) is an order (biology), order of insects that includes butterfly, butterflies and moths (both are called lepidopterans). About 180,000 species of the Lepidoptera are described, in 126 Family (biology), families and 46 Taxonomic rank, superfamilies, 10 percent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most wikt:speciose, speciose orders, along with the Hymenoptera, fly, Diptera, and beetle, Coleoptera. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, wings, and a proboscis. The scales are modified, flattened "hairs", and give ...

Caterpillar
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of caterpi ...
