Army Cutworm
The army cutworm is the immature form of ''Euxoa auxiliaris''. The adult moth is called a "miller moth" because of the fine scales on its wings that rub off easily and remind people of the dusty flour that covers the clothing of a miller. These native North American larvae consume emerging small grains, alfalfa, and canola in the southern Great Plains and southern Canada. Larvae feed above ground at night and usually hide in soil during daylight, but will also feed on cloudy days. On dry, low elevation rangelands of the U.S. Intermountain West, army cutworms consume exotic cheatgrass (''Bromus tectorum'') and mustards to produce cheatgrass "die-offs." Within these bare areas, the larvae also defoliate native shrubs including four-wing saltbush (''Atriplex canescens'') and sagebrush (''Artemisia'' spp.). The miller moth is a seasonal nuisance in the spring in states including Colorado, Wyoming, New Mexico and Kansas, as they hatch in the low-lying farmlands, then migrate to hi ...

Augustus Radcliffe Grote
Augustus Radcliffe Grote (February 7, 1841 – September 12, 1903) was a British entomologist who described over 1,000 species of butterflies and moths.Osborn, H. 1937. Fragments of Entomological History. Columbus, OH: Published by the author. He is best known for his work on North American Noctuidae. A number of species were named after him, including the moth '' Horama grotei''. Early life and family Grote was born in Aigburth, a suburb of Liverpool, in 1841. His mother was English, and his maternal grandfather, Augustus Radcliffe, was a partner in the house of Sir Joseph Bailey. Grote was a first cousin on his mother's side to Ethel Romanes. Grote's father was born in Danzig, and his paternal lineage traced back to Dutch philosopher Hugo Grotius. His family name was changed from 'Grohté' to 'Grote' when his father became an English citizen. Augustus Grote came to New York at age 7, one year after his parents had moved there from England, and spent his youth on St ...

Euxoa Auxiliaris Caterpillar
''Euxoa'' is a genus of moths of the family Noctuidae raised to Genus by the German entomologist, Jacob Hübner. The Genus is mostly confined to dry and semi dry areas in the Northern Hemisphere. There 130 species in Eurasia, a few in Africa, and 175 in North America. There are no species in the Genus in South-East Asia or in Australia. In North America, most species are found in Western regions. Of the North American species, 4 are endemic to Mexico. There is one species recorded from Chile, but this may be a mislabeled specimen. In real terms, species numbers do not equal species abundance. Some areas with few species have large numbers of the ones that do live there. In North America there are 7 subgenera - ''Chorizagrotis'', ''Palaeoeuxoa'', ''Heteroeuxoa'',''Longivesica'', ''Pleuonectopoda'', ''Orstagrotis'', and ''Euxoa''. The larvae of this ''Genus'' are Cutworms, living in the soil but feeding on the surface. A few species also climb. Most larval Euxoa hatch from egg ...

Cheatgrass
''Bromus tectorum'', known as downy brome, drooping brome or cheatgrass, is a winter annual grass native to Europe, southwestern Asia, and northern Africa, but has become invasive in many other areas. It now is present in most of Europe, southern Russia, Japan, South Africa, Australia, New Zealand, Iceland, Greenland, North America and western Central Asia. In the eastern US ''B. tectorum'' is common along roadsides and as a crop weed, but usually does not dominate an ecosystem. It has become a dominant species in the Intermountain West and parts of Canada, and displays especially invasive behavior in the sagebrush steppe ecosystems where it has been listed as noxious weed. ''B. tectorum'' often enters the site in an area that has been disturbed, and then quickly expands into the surrounding area through its rapid growth and prolific seed production. The reduction of native plants and the increased fire frequency caused by ''B. tectorum'' prompted the United States Fish and Wil ...

Four-wing Saltbush
''Atriplex canescens'' (or chamiso, chamiza, four-wing saltbush) is a species of evergreen shrub in the family Amaranthaceae native to the western and midwestern United States. Description ''Atriplex canescens'' has a highly variable form, and readily hybridizes with several other species in the genus '' Atriplex''. The degree of polyploidy also results in variations in form. Its height can vary from 1 foot to 10 feet, but 2 to 4 feet is most common. The leaves are thin and 0.5 to 2 inches long. It is most readily identified by the fruits, which have four wings at roughly 90 degree angles and are densely packed on long stems. This species blooms from April to October. Habitat Fourwing saltbush is most common in early succession areas such as disturbed sites and active sand dunes. It is also found in more mature successions dominated by sagebrush—''Artemisia tridentata'' and shadscale. Uses Among the Zuni people, an infusion of dried root and blossoms or a poultice ...

Kansas
Kansas () is a state in the Midwestern United States. Its capital is Topeka, and its largest city is Wichita. Kansas is a landlocked state bordered by Nebraska to the north; Missouri to the east; Oklahoma to the south; and Colorado to the west. Kansas is named after the Kansas River, which in turn was named after the Kansa Native Americans who lived along its banks. The tribe's name (natively ') is often said to mean "people of the (south) wind" although this was probably not the term's original meaning. For thousands of years, what is now Kansas was home to numerous and diverse Native American tribes. Tribes in the eastern part of the state generally lived in villages along the river valleys. Tribes in the western part of the state were semi-nomadic and hunted large herds of bison. The first Euro-American settlement in Kansas occurred in 1827 at Fort Leavenworth. The pace of settlement accelerated in the 1850s, in the midst of political wars over the slavery deba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insect Migration
Insect migration is the seasonal movement of insects, particularly those by species of dragonflies, beetles, butterflies and moths. The distance can vary with species and in most cases, these movements involve large numbers of individuals. In some cases, the individuals that migrate in one direction may not return and the next generation may instead migrate in the opposite direction. This is a significant difference from bird migration. Definition All insects move to some extent. The range of movement can vary from within a few centimeters for some sucking insects and wingless aphids to thousands of kilometers in the case of other insects such as locusts, butterflies and dragonflies. The definition of migration is therefore particularly difficult in the context of insects. A behavior-oriented definition proposed is This definition disqualifies movements made in the search of resources and which are terminated upon finding the resource. Migration involves longer distance move ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpine Climate
Alpine climate is the typical weather ( climate) for elevations above the tree line, where trees fail to grow due to cold. This climate is also referred to as a mountain climate or highland climate. Definition There are multiple definitions of alpine climate. In the Köppen climate classification, the alpine and mountain climates are part of group ''E'', along with the polar climate, where no month has a mean temperature higher than . According to the Holdridge life zone system, there are two mountain climates which prevent tree growth : a) the alpine climate, which occurs when the mean biotemperature of a location is between . The alpine climate in Holdridge system is roughly equivalent to the warmest tundra climates (ET) in the Köppen system. b) the alvar climate, the coldest mountain climate since the biotemperature is between 0 °C and 1.5 °C (biotemperature can never be below 0 °C). It corresponds more or less to the coldest tundra climates and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brown Bear
The brown bear (''Ursus arctos'') is a large bear species found across Eurasia and North America. In North America, the populations of brown bears are called grizzly bears, while the subspecies that inhabits the Kodiak Islands of Alaska is known as the Kodiak bear. It is one of the largest living terrestrial members of the order Carnivora, rivaled in size only by its closest relative, the polar bear (''Ursus maritimus''), which is much less variable in size and slightly bigger on average. The brown bear's range includes parts of Russia, Central Asia, the Himalayas, China, Canada, the United States, Hokkaido, Scandinavia, Finland, the Balkans, the Picos de Europa and the Carpathian region (especially Romania), Iran, Anatolia, and the Caucasus. The brown bear is recognized as a national and state animal in several European countries. While the brown bear's range has shrunk, and it has faced local extinctions across its wide range, it remains listed as a least concern spec ...
