Tigrosa Aspersa
''Tigrosa aspersa'' is a large (up to one-inch (25 mm) body length) wolf spider that inhabits the eastern United States. Compared to its close relative ''Tigrosa helluo'', ''T. aspersa'' is much larger. This species was known as ''Hogna aspersa'' prior to 2012, when it was moved to ''Tigrosa''.

Nicholas Marcellus Hentz
Nicholas Marcellus Hentz (July 25, 1797 – November 4, 1856) was a French American educator and arachnologist. Biography Hentz was born in Versailles, France. He was the youngest child of Charles Nicholas Arnould Hentz and Marie-Anne Therese Daubree Hentz. He studied medicine and learned the art of miniature painting in Paris. His father was an active Republican and participant in the French Revolution. Upon the restoration of the Bourbons in 1815, his father was banished from France. So, in 1816, Marcellus immigrated with his family to the United States, where they settled in Wilkes-Barre, Pennsylvania. He taught French and miniature painting in Boston, Philadelphia, and other places. He became a member of the Academy of Natural Sciences of Philadelphia (ANSP) in 1819. His illustrations were published in their journal. Among these illustrations are three well known watercolors, two of which are of freshwater fish from Alabama (painted in 1847) and one is a miniature of Hentz's ...

Wolf Spider
Wolf spiders are members of the family Lycosidae (). They are robust and agile hunters with excellent eyesight. They live mostly in solitude, hunt alone, and do not spin webs. Some are opportunistic hunters, pouncing upon prey as they find it or chasing it over short distances; others wait for passing prey in or near the mouth of a burrow. Wolf spiders resemble nursery web spiders (family Pisauridae), but wolf spiders carry their egg sacs by attaching them to their spinnerets, while the Pisauridae carry their egg sacs with their chelicerae and pedipalps. Two of the wolf spider's eight eyes are large and prominent; this distinguishes them from nursery web spiders, whose eyes are all of roughly equal size. This can also help distinguish them from the similar-looking grass spiders. Description The many genera of wolf spiders range in body size (legs not included) from less than . They have eight eyes arranged in three rows. The bottom row consists of four small eyes, the middle ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

Tigrosa Helluo
''Tigrosa helluo'' is a species of spider belonging to the family Lycosidae, also known as wolf spiders. ''T. helluo'' was formerly known as ''Hogna helluo'' before differences between dorsal color patterns, habitat preferences, body structures, etc. were discovered. The species is native to the United States, Canada, and Mexico. It can be found across the eastern half of the United States, primarily in the Northeast and New England, and as far west as Nebraska and Kansas. ''T. helluo'' can be found in diverse habitats including woods, marshes, fields, and riparian areas. Typically, members of this species prefer to live in wetter areas as opposed to dry environments. Males tend to live for around a year and females will live for close to two years. The defining characteristic of ''T. helluo'' is its brown carapace and distinct yellow stripe starting from its anterior eyes extending down the cephalothorax. The underside of the abdomen has distinct black spots that d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tigrosa
''Tigrosa'' is a genus of spiders in the family Lycosidae, found in North America. Taxonomy The genus ''Tigrosa'' was erected by Allen R. Brady in 2012. Prior to 1990, many medium to large wolf spiders (family Lycosidae) from North America were placed in the genus ''Lycosa''. In 1990 it was accepted that ''Lycosa'' was a Mediterranean genus and did not occur in North America; seven species were transferred to ''Hogna''. A more detailed examination of the type species of ''Hogna'', ''Hogna radiata'', convinced Brady that a new genus was needed for some of the North American species that had been moved to ''Hogna''. Characters that distinguish ''Tigrosa'' from ''Hogna'' include the pattern on the upper (dorsal) surface of the cephalothorax, the arrangement of the eyes, and the shape of the female epigyne. The generic name ''Tigrosa'' is intended to mean "fierce like a tiger", referring to the patterning and behaviour of ''Tigrosa'' species. Species , the World Spider Catalog acc ...

Lycosa Implacida
''Lycosa'' is a genus of wolf spiders distributed throughout most of the world. Sometimes called the "true tarantula", though not closely related to the spiders most commonly called tarantulas today, ''Lycosa'' spp. can be distinguished from common wolf spiders by their relatively large size. This genus includes the European ''Lycosa tarantula'', which was once associated with tarantism, a dubious affliction whose symptoms included shaking, cold sweats, and a high fever, asserted to be curable only by the traditional tarantella dance. No scientific substantiation of that myth is known; the venom of ''Lycosa'' spiders is generally not harmful. As of November 2020, more than 200 species in this genus had been described.Planas, E., Fernández-Montraveta, C., & Ribera, C.

Hercule Nicolet
Hercule Nicolet (18 January 1801 Neuchâtel – 16 September 1872) born Louis-Ami-Hercule Nicolet, was a Swiss lithographer, natural history illustrator, librarian at ''École nationale vétérinaire d'Alfort'' from 1861 to 1870, and entomologist who specialized in Thysanura and Collembola. Hercule Nicolet was the son of Bénédict-Alphonse Nicolet (1743-1807). He was the business partner of Jean Coulin (1822-1883) in the lithographic firm of Hercule "Nicolet and Coulin fils", pressing the plates for ''Mémoires de la Société des Sciences Naturelles de Neuchâtel'' co-edited by Louis Agassiz and many other geological and natural history works. He wrote ''Recherches pour Servir á l'Histoire des Podurelles.'' ''Nouv. Mém. Soc. Helvet. Sci. Nat''., 6, p.1-88 (1842) and "Essai sur une classification des insectes aptères, de l'ordre des Thysanoures" (Séance du 25 Mars 1846) in the ''Annales de la Société Entomologique de France'', 2e Série, Tome V, p. 335-395 (1847).

Spiders Of The United States
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate t ...
