Henry Ellsworth Ewing
Henry Ellsworth Ewing (11 February 1883 – 5 January 1951) was an American arachnologist. He worked at several universities, but spent most of his career at the Bureau of Entomology and Plant Quarantine. Ewing was considered an authority on arachnids, particularly mites. Early life and education Henry Ellsworth Ewing was born on 11 February 1883 in Arcola, Illinois. He attended Knox College and obtained a bachelor's degree at the University of Illinois in 1906. In 1908, he received a master's degree from the University of Illinois. In 1906 and 1907, he was a student at the University of Chicago. In 1910 and 1911, he was a Schuyler fellow at Cornell University, which is where he earned his PhD in 1911. Career From 1908 to 1909, Ewing taught high school. Ewing's first job in the biological sciences was as an Assistant Entomologist at Oregon State University. He held this position from 1911 to 1914. He then worked at Iowa State University as an assistant professor of zoology and e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mites
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are predators or parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two distinct groups of arachnids ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trombiculidae
Trombiculidae (); commonly referred to in North America as chiggers and in Britain as harvest mites, but also known as berry bugs, bush-mites, red bugs or scrub-itch mites, are a family of mites. Chiggers are often confused with Tunga penetrans, jiggers – a type of flea. Several species of Trombiculidae in their larva stage bite their animal or human host and by embedding their mouthparts into the skin cause "intense irritation" or "a wheal response, wheal, usually with severe itching and dermatitis". Trombiculidae live in forests and grasslands and are also found in the vegetation of low, damp areas such as woodlands, berry bushes, orchards, along lakes and streams, and even in drier places where vegetation is low, such as lawns, golf courses, and parks. They are most numerous in early summer when grass, weeds, and other vegetation are heaviest. In their larval stage, they attach to various animals, including humans, and feed on skin, often causing itching. These relatives of ...

Arizona Myotis
The Arizona myotis (''Myotis occultus'') is a vesper bat species inhabiting much of the southwestern United States and central Mexico as far south as the Distrito Federal. Taxonomy and etymology It was described as a new species in 1909 by American zoologist Ned Hollister. The holotype was collected near Needles, California, in 1905. Its specific name "''occultus''" is Latin for "hidden or concealed". Description It is a small species with a total length of — of the total length, consists of its tail. Its fur is glossy brown with a cinnamon tint. The ventral fur and its face are paler brown. Range and habitat Its range includes parts of the Southwestern United States and the Mexican state of Chihuahua. It is found in a range of elevations from near sea level to above sea level. Conservation As of 2018, it is evaluated as a least-concern species by the IUCN. It meets the criteria for this classification because it has a wide geographic range, its range includes protect ...

Little Brown Bat
The little brown bat or little brown myotis (''Myotis lucifugus'') is an endangered species of mouse-eared microbat found in North America. It has a small body size and glossy brown fur. It is similar in appearance to several other mouse-eared bats, including the Indiana bat, northern long-eared bat, and Arizona myotis, to which it is closely related. Despite its name, the little brown bat is not closely related to the big brown bat, which belongs to a different genus. Its mating system is polygynandrous, or promiscuous, and females give birth to one offspring annually. The offspring, called pups, are quickly weaned and reach adult size in some dimensions by three weeks old. The little brown bat has a mean lifespan of 6.5 years, though one individual in the wild reached 34 years old. It is nocturnal, foraging for its insect prey at night and roosting in hollow trees or buildings during the day, among less common roost types. It navigates and locates prey with echolocation. ...

Myotis Septentrionalis
''Myotis septentrionalis'', known as the northern long-eared bat or northern myotis, is a species of bat native to North America. There are no recognized subspecies. The northern long-eared bat is about 3–3.7 inches in length, with a wingspan of 9–10 inches. It is distinguishable by its long ears when comparing it to other bats in its genus. This species is commonly found in the northern United States and Southern Canada east of British Columbia. The geographic range includes 37 states. Description The northern long-eared bat is a small bat, measuring an average of in total length, including a tail about long. Adults weigh between . The fur and wing membranes are light brown in color, and the bat lacks the dark shoulder spots found in the closely related, and otherwise similar Keen's myotis (''Myotis keenii''). Compared to other ''Myotis'' species, these bats have long ears with a relatively long, pointed tragus; when folded forwards the ears extend well past the nose. The ...

Animals Described In 1929
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the ec ...
