Rainbow Grasshopper
''Dactylotum bicolor'', also known as the rainbow grasshopper, painted grasshopper, or the barber pole grasshopper, is a species of grasshopper in the family Acrididae. It is native to the United States, Canada and northern Mexico and exhibits aposematism (warning coloration). It was first described by the German entomologist Toussaint de Charpentier in 1843. Description ''Dactylotum bicolor'' grows to an average length of about for males and for females. It is mainly black with distinctive reddish and yellowish markings, a pale green prothorax and pale green wingpads. The tibia of the hind leg bears six to eight spines. This species does not develop wings and is unable to fly. Three subspecies are recognised: * ''D. b. bicolor'' – Northern Texas, New Mexico and Mexico * ''D. b. pictum'' – Northern and eastern part of range * ''D. b. variegatum'' – Southern Arizona and western part of range The coloring varies across the insect's range, with ''D. b. pictum'' being bl ...

Centromere
The centromere links a pair of sister chromatids together during cell division. This constricted region of chromosome connects the sister chromatids, creating a short arm (p) and a long arm (q) on the chromatids. During mitosis, spindle fibers attach to the centromere via the kinetochore. The physical role of the centromere is to act as the site of assembly of the kinetochores – a highly complex multiprotein structure that is responsible for the actual events of chromosome segregation – i.e. binding microtubules and signaling to the cell cycle machinery when all chromosomes have adopted correct attachments to the spindle, so that it is safe for cell division to proceed to completion and for cells to enter anaphase. There are, broadly speaking, two types of centromeres. "Point centromeres" bind to specific proteins that recognize particular DNA sequences with high efficiency. Any piece of DNA with the point centromere DNA sequence on it will typically form a centromere if pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aposematic Animals
Aposematism is the Advertising in biology, advertising by an animal to potential predation, predators that it is not worth attacking or eating. This unprofitability may consist of any defences which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature. These advertising signals may take the form of conspicuous animal coloration, coloration, sounds, odours, or other perception, perceivable characteristics. Aposematic signals are beneficial for both predator and prey, since both avoid potential harm. The term was coined in 1877 by Edward Bagnall Poulton for Alfred Russel Wallace's concept of warning coloration. Aposematism is exploited in Müllerian mimicry, where species with strong defences evolve to resemble one another. By mimicking similarly coloured species, the warning signal to predators is shared, causing them to learn more quickly at less of a cost. A genuine aposematic signal that a species actually ...

Insects Described In 1843
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orthoptera Of North America
Orthoptera () is an order of insects that comprises the grasshoppers, locusts, and crickets, including closely related insects, such as the bush crickets or katydids and wētā. The order is subdivided into two suborders: Caelifera – grasshoppers, locusts, and close relatives; and Ensifera – crickets and close relatives. More than 20,000 species are distributed worldwide. The insects in the order have incomplete metamorphosis, and produce sound (known as a "stridulation") by rubbing their wings against each other or their legs, the wings or legs containing rows of corrugated bumps. The tympanum, or ear, is located in the front tibia in crickets, mole crickets, and bush crickets or katydids, and on the first abdominal segment in the grasshoppers and locusts. These organisms use vibrations to locate other individuals. Grasshoppers and other orthopterans are able to fold their wings (i.e. they are members of Neoptera).

Mutillidae
The Mutillidae are a family of more than 7,000 species of wasps whose wingless females resemble large, hairy ants. Their common name velvet ant refers to their dense pile of hair, which most often is bright scarlet or orange, but may also be black, white, silver, or gold. Their bright colors serve as aposematic signals. They are known for their extremely painful stings, (the sting of the species ''Dasymutilla klugii'' rated a 3 on the Schmidt pain index and lasts up to 30 minutes), and has resulted in the common name "cow killer" or "cow ant" being applied to the species '' Dasymutilla occidentalis.'' However, mutillids are not aggressive and sting only in defense. In addition, the actual toxicity of their venom is much lower than that of honey bees or harvester ants. Unlike true ants, they are solitary, and lack complex social systems. Distribution Mutillidae can be found worldwide with about 230 genera or subgenera and around 8,000 species worldwide. Over 400 species occur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lygaeoidea
The Lygaeoidea are a sizeable superfamily of true bugs, containing seed bugs and allies, in the order Hemiptera. There are about 16 families and more than 4,600 described species in Lygaeoidea, found worldwide. Most feed on seeds or sap, but a few are predators. The ash-gray leaf bug family ( Piesmatidae) is generally considered a member of the superfamily Lygaeoidea, but in the past it was sometimes placed in its own superfamily. Families These 16 families belong to the superfamily Lygaeoidea. The majority of them were considered to be part of the family Lygaeidae before Thomas J. Henry's work was published in 1997. * Artheneidae Stål, 1872 * Berytidae Fieber, 1851 (stilt bugs) * Blissidae Stål, 1862 * Colobathristidae Stal, 1865 * Cryptorhamphidae * Cymidae Baerensprung, 1860 * Geocoridae Baerensprung, 1860 (big-eyed bugs) * Heterogastridae Stål, 1872 * Lygaeidae The Lygaeidae are a family in the Hemiptera (true bugs), with more than 110 genera in four subfami ...

Little Striped Whiptail
The little striped whiptail (''Aspidoscelis inornatus'') is a species of lizard found in the southwestern United States (in Arizona, New Mexico and Texas) and in northern Mexico (in Chihuahua, Coahuila, Durango, Zacatecas, San Luis Potosí, and Nuevo León). A significant amount of research was done on the species during the mid-1990s, with several new subspecies being added, many of which some sources consider to be distinct enough to warrant full species status, and the research is ongoing. It is called ''little'' to distinguish it from many other species known as striped whiptails and to indicate that it is the smallest of those species. Description The little striped whiptail grows from 6.5 to 9.5 inches in length. It is typically black in color, with yellow or white striping from head to tail, and a light blue underside. It is slender bodied, with a blue colored tail approximately three times the body length. The blue coloration is much more pronounced on males ...

Thermoregulation
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation. The internal thermoregulation process is one aspect of homeostasis: a state of dynamic stability in an organism's internal conditions, maintained far from thermal equilibrium with its environment (the study of such processes in zoology has been called physiological ecology). If the body is unable to maintain a normal temperature and it increases significantly above normal, a condition known as hyperthermia occurs. Humans may also experience lethal hyperthermia when the wet bulb temperature is sustained above for six hours. The opposite condition, when body temperature decreases below normal levels, is known as hypothermia. It results when the homeostatic c ...
