Asclepias Tuberosa
''Asclepias tuberosa'', commonly known as butterfly weed, is a species of milkweed native to eastern and southwestern North America. It is commonly known as butterfly weed because of the butterflies that are attracted to the plant by its color and its copious production of nectar.(1) (2) Description It is a perennial plant growing to tall. The leaves are spirally arranged, lanceolate, long, and broad. From April to September, in the upper axils, –wide umbels of orange, yellow or red flowers wide appear. They each have five petals and five sepals. It is uncertain if reddish flowers are due to soil mineral content, ecotype genetic differentiation, or both. A cultivar named 'Hello Yellow' typically has more yellowish flowers than ordinary examples of this plant. The fruit pod is long, containing many long-haired seeds. Similar species The plant looks similar to the lanceolate milkweed ('' Asclepias lanceolata''), but is uniquely identified by the larger number of flower ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Becker County, Minnesota
Becker County is a county in the U.S. state of Minnesota. As of the 2020 census, the population was 35,183. Its county seat is Detroit Lakes. Part of the White Earth Indian Reservation extends into the county. The county was created in 1858 and organized in 1871. History Becker County became a county on March 18, 1858. It was named for George Loomis Becker, one of three men elected to Congress when Minnesota became a state. Since Minnesota could only send two, Becker elected to stay behind, and he was promised to have a county named after him. Colonel George Johnston founded the city of Detroit Lakes in 1871. It grew quickly with the construction of the Northern Pacific Railroad. Johnston led settlers from New England to settle in this region. An 1877 election decided that Detroit Lakes, then known as Detroit, would become the county seat. Detroit won the election by a 90% majority. Frazee, Lake Park, and Audubon were also in the running. In 1884, Detroit Lakes had many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cardenolide
A cardenolide is a type of steroid. Many plants contain derivatives, collectively known as cardenolides, including many in the form of cardenolide glycosides (cardenolides that contain structural groups derived from sugars). Cardenolide glycosides are often toxic; specifically, they are heart-arresting. Cardenolides are toxic to animals through inhibition of the enzyme Na+/K+‐ATPase, which is responsible for maintaining the sodium and potassium ion gradients across the cell membranes. Etymology The term derives from ''card-'' "heart" (from Greek καρδία ''kardiā'') and the suffix ''-enolide'', referring to the lactone ring at C17. Cardenolides are a class of steroids (or aglycones if viewed as cardiac glycoside constituents), and cardenolides are a subtype of this class (see MeSH D codes list). Structure Cardenolides are C(23)-steroids with methyl groups at C-10 and C-13 and a five-membered lactone (specifically a butenolide) at C-17. They are aglycone constituents of ...

Milkweed Tussock Moth
''Euchaetes egle'', the milkweed tiger moth or milkweed tussock moth, is a moth in the family Erebidae and the tribe Arctiini, the tiger moths. The species was first described by Dru Drury in 1773. It is a common mid- through late summer feeder on milkweeds and dogbane. Like most species in this family, it has chemical defenses it acquires from its host plants, in this case, cardiac glycosides. These are retained in adults and deter bats, and presumably other predators, from feeding on them.Hristov, N. L. & Conner, W. E. (2005). "Effectiveness of tiger moth (Lepidoptera, Arctiidae) chemical defenses against an insectivorous bat (''Eptesicus fuscus'')". ''Chemoecology''. 15 (2): 105–113. Only very high cardiac glycoside concentrations deterred bats, however. Adults indicate their unpalatability to bats with ultrasonic clicks from their tymbal organs. Range It is found from southern Canada and south through Texas and Florida in North America.*Wagner, D. L. (2005). ''Caterpillars ...

Dogbane Tiger Moth
''Cycnia tenera'', the dogbane tiger moth or delicate cycnia, is a moth in the family Erebidae. It occurs throughout North America, from southern British Columbia to Nova Scotia southwards to Arizona and Florida. The species is distasteful and there is evidence that it emits aposematic ultrasound signals; these may also jam bat echolocation, as the functions are not mutually exclusive. Ecology It is a common feeder on ''Apocynum cannabinum'' (dogbane, Indian hemp) which produces a milky latex containing cardenolides, toxic cardiac glycoside that defend against herbivores. It also feeds on milkweed species, ''Asclepias'', at least in parts of its range, but is most commonly reported from dogbane. Its interactions with bats have been much studied, but are an area of dispute regarding whether the clicks emitted by adult moths are disruptive of bat echolocation, or merely aposematic warning signals. The two functions are not mutually exclusive, however, so it may not be possible to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monarch Butterflies
The monarch butterfly or simply monarch (''Danaus plexippus'') is a milkweed butterfly (subfamily Danainae) in the family Nymphalidae. Other common names, depending on region, include milkweed, common tiger, wanderer, and black-veined brown. It is amongst the most familiar of North American butterflies and an iconic pollinator, although it is not an especially effective pollinator of milkweeds. Its wings feature an easily recognizable black, orange, and white pattern, with a wingspan of . A Müllerian mimic, the viceroy butterfly, is similar in color and pattern, but is markedly smaller and has an extra black stripe across each hindwing. The eastern North American monarch population is notable for its annual southward late-summer/autumn instinctive migration from the northern and central United States and southern Canada to Florida and Mexico. During the fall migration, monarchs cover thousands of miles, with a corresponding multigenerational return north in spring. The western ...

Queen (butterfly)
The queen butterfly (''Danaus gilippus'') is a North and South American butterfly in the family Nymphalidae with a wingspan of . It is orange or brown with black wing borders and small white forewing spots on its dorsal wing surface, and reddish ventral wing surface fairly similar to the dorsal surface. The ventral hindwings have black veins and small white spots in a black border. The male has a black androconial scent patch on its dorsal hindwings. It can be found in meadows, fields, marshes, deserts, and at the edges of forests. This species is possibly a close relative to the similarly colored soldier butterfly (or tropical queen, '' D. eresimus''), in any case, it is not close to the plain tiger ('' D. chrysippus'', African queen) as was long believed. There are seven subspecies. Females lay one egg at a time on larval host plants. Larvae use these plants as a food source, whereas adult butterflies feed mainly on nectar from flowers. Unpalatability to avian predators is a fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
