Grasshopper Club Zürich Players
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are among what is possibly the most ancient living group of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago. Grasshoppers are typically ground-dwelling insects with powerful hind legs which allow them to escape from threats by leaping vigorously. As hemimetabolous insects, they do not undergo complete metamorphosis; they hatch from an egg into a nymph or "hopper" which undergoes five moults, becoming more similar to the adult insect at each developmental stage. The grasshopper hears through the tympanal organ which can be found in the first segment of the abdomen attached to the thorax; while its sense of vision is in the compound eyes, the change in light intensity is perceived in the simple eyes (ocelli). At high population densities and under certain environmental conditions, some grasshopper species can change color and behavior and form swarms. Under ...

Induan
The Induan is the first age of the Early Triassic epoch in the geologic timescale, or the lowest stage of the Lower Triassic series in chronostratigraphy. It spans the time between 251.902 Ma and Ma (million years ago). The Induan is sometimes divided into the Griesbachian and the Dienerian subages or substages. The Induan is preceded by the Changhsingian (latest Permian) and is followed by the Olenekian. The Induan is roughly coeval with the regional Feixianguanian Stage of China. Geology Stratigraphy The Triassic is the first period of the Mesozoic era. It is subdivided into the Lower, Middle, and Upper Triassic series, which are further subdivided into stages. The Induan is the first stage of the Lower Triassic, from 251.9 million to 251.2 million years ago, spanning the first 700,000 years after the Permian–Triassic extinction event. Stages can be defined globally or regionally. For global stratigraphic correlation, the International Commission on Stratigrap ...

Nymph (biology)
In biology, a nymph is the immature form of some invertebrates, particularly insects, which undergoes gradual metamorphosis ( hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph's overall form already resembles that of the adult, except for a lack of wings (in winged species). In addition, while a nymph moults, it never enters a pupal stage. Instead, the final moult results in an adult insect. Nymphs undergo multiple stages of development called instars. This is the case, for example, in Orthoptera ( crickets, grasshoppers and locusts), Hemiptera ( cicadas, shield bugs, whiteflies, aphids, leafhoppers, froghoppers, treehoppers etc.), mayflies, termites, cockroaches, mantises, stoneflies and Odonata ( dragonflies and damselflies). Nymphs of aquatic insects, as in the Odonata, Ephemeroptera, and Plecoptera, are also called naiads, an Ancient Greek name for mythological water nymphs. Usage of the term 'naiad' is no longer popular among ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bush-cricket
Insects in the family Tettigoniidae are commonly called katydids (especially in North America), or bush crickets. They have previously been known as "long-horned grasshoppers". More than 8,000 species are known. Part of the suborder Ensifera, the Tettigoniidae are the only extant (living) family in the superfamily Tettigonioidea. They are primarily nocturnal in habit with strident mating calls. Many species exhibit mimicry and camouflage, commonly with shapes and colors similar to leaves. Etymology The family name Tettigoniidae is derived from the genus '' Tettigonia'', first described by Carl Linnaeus in 1758. In Latin ''tettigonia'' means a kind of small cicada, leafhopper; it is from the Greek τεττιγόνιον ''tettigonion'', the diminutive of the imitative (onomatopoeic) τέττιξ, ''tettix'', cicada. All of these names such as ''tettix'' with repeated sounds are onomatopoeic, imitating the stridulation of these insects. The common name ''katydid'' is also on ...

Acrididea
Acrididea including the Acridomorpha is an infraorder of insects that describe the grasshoppers (thus also locusts) and ground-hoppers. It contains a large majority of species in the suborder Caelifera and the taxon Acridomorpha may also be used, which excludes the Tetrigoidea. Both names are derived from older texts, such as Imms,Imms AD, rev. Richards OW & Davies RG (1970) ''A General Textbook of Entomology'' 9th Ed. Methuen 886 pp. which placed the "short-horned grasshoppers" and locusts at the family level (Acrididae). The study of grasshopper species is called acridology. Acridomorpha The ''Orthoptera Species File'' lists the following superfamilies: most families and species belong to the Acridoidea. *Acridoidea (MacLeay, 1821) *Eumastacoidea Burr, 1899 ** Chorotypidae Stål, 1873 ** Episactidae Burr, 1899 ** Eumastacidae Burr, 1899 ** Euschmidtiidae Rehn, 1948 ** Mastacideidae Rehn, 1948 ** Morabidae Rehn, 1948 ** † Promastacidae Kevan & Wighton, 1981 ** Thericl ...

Acridology
Orthopterology is the scientific study of the order Orthoptera, which includes grasshoppers, crickets, locusts and some other insects. Someone that studies in this field is an orthopterist. The term is derived from the Ancient Greek words and , meaning ''straight'' and ''wing'' respectively, with the English suffix ''-logy''.This ultimately derives from Greek , but via Latin ''-logia'' and French ''-logie''. Orthopterology as a science A notable branch of orthopterology is , which focuses on locusts and grasshoppers in the family Acrididae and is relevant to famine prevention. Orthopterological societies * Association for Applied Acridology International * Orthopterists' Society * German Society for Orthopterology Orthopterological Journals * Journal of Orthoptera Research A journal, from the Old French ''journal'' (meaning "daily"), may refer to: *Bullet journal, a method of personal organization * Diary, a record of what happened over the course of a day or other period ...

History Of Ancient Israel And Judah
The history of ancient Israel and Judah begins in the Southern Levant during the Late Bronze Age and Early Iron Age. "Israel" as a people or tribal confederation (see Israelites) appears for the first time in the Merneptah Stele, an inscription from ancient Egypt that dates to about 1208 BCE. According to modern archaeology, ancient Israelite culture developed as an outgrowth from the Canaanites. Two related Israelite polities known as the Kingdom of Israel and the Kingdom of Judah had emerged in the region by Iron Age II. According to the Hebrew Bible, a " United Monarchy" (consisting of Israel and Judah) existed as early as the 11th century BCE, under the reigns of Saul, David, and Solomon; the country later would have split into two separate kingdoms: Israel (containing the cities of Shechem and Samaria) in the north and Judah (containing Jerusalem and the Jewish Temple) in the south. The historicity of the United Monarchy is debated as there are no archaeological rema ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasitoid
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host (biology), host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionarily stable strategy, evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation. Among parasitoids, strategies range from living inside the host (''endoparasitism''), allowing it to continue growing before emerging as an adult, to Paralysis, paralysing the host and living outside it (''ectoparasitism''). Hosts can include other parasitoids, resulting in hyperparasitism; in the case of oak galls, up to five levels of parasitism are possible. Some parasitoids Behavior-altering parasite, influence their host's behaviour in ways that favour the propagation of the parasitoid. Parasitoids are found in a variety of Taxon, taxa across the insect superorder Endopterygota, whose compl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warning Coloration
Aposematism is the advertising by an animal to potential 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 coloration, sounds, odours, or other 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 possesses chemical or physical defences is not the only way ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Deimatic Behaviour
Deimatic behaviour or startle display means any pattern of bluffing behaviour in an animal that lacks strong defences, such as suddenly displaying conspicuous eyespots, to scare off or momentarily distract a predator, thus giving the prey animal an opportunity to escape. The term deimatic or dymantic originates from the Greek δειματόω (deimatóo), meaning "to frighten". Deimatic display occurs in widely separated groups of animals, including moths, butterflies, mantises and phasmids among the insects. In the cephalopods, different species of octopuses, squids, cuttlefish and the paper nautilus are deimatic. Displays are classified as deimatic or aposematic by the responses of the animals that see them. Where predators are initially startled but learn to eat the displaying prey, the display is classed as deimatic, and the prey is bluffing; where they continue to avoid the prey after tasting it, the display is taken as aposematic, meaning the prey is genuinely dist ...

Camouflage
Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate, as well as making general aiming easier. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Predator
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate ...
