Grasshopper
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. Unde ...

Locust
Locusts (derived from the Vulgar Latin ''locusta'', meaning grasshopper) are various species of short-horned grasshoppers in the family Acrididae that have a swarming phase. These insects are usually solitary, but under certain circumstances they become more abundant and change their behaviour and habits, becoming gregarious. No taxonomic distinction is made between locust and grasshopper species; the basis for the definition is whether a species forms swarms under intermittently suitable conditions; this has evolved independently in multiple lineages, comprising at least 18 genera in 5 different acridid subfamilies. Normally, these grasshoppers are innocuous, their numbers are low, and they do not pose a major economic threat to agriculture. However, under suitable conditions of drought followed by rapid vegetation growth, serotonin in their brains triggers dramatic changes: they start to breed abundantly, becoming gregarious and nomadic (loosely described as migratory) ...

Caelifera
The Caelifera are a suborder of orthopteran insects. They include the grasshoppers and grasshopper-like insects, as well as other superfamilies classified with them: the ground-hoppers (Tetrigoidea) and pygmy mole crickets ( Tridactyloidea). The latter should not be confused with the mole crickets ( Gryllotalpidae), which belong to the other Orthopteran sub-order Ensifera. The name of this suborder comes from Latin meaning ''chisel-bearing'' ("chisel" in Latin: ''caelum''), referring to the "stout" shape of its species' ovipositors. Subdivisions and their distribution The Caelifera include some 2,400 valid genera and about 12,000 known species. Many undescribed species probably exist, especially in tropical forests. The Caelifera have a predominantly tropical distribution (as with most Orthoptera) with fewer species known from temperate climate zones. Caelifera are divided into two infraorders: the more basal Tridactylidea and the Acrididea or grasshopper-like species. Th ...

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 ...

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] |
Pyrgomorphidae
Pyrgomorphidae is a family of grasshoppers in the order Orthoptera; it is the only family in the superfamily Pyrgomorphoidea, with a pan-tropical distribution. Their name is probably derived from ''pyrgos'' (Greek: ''Πύργος'') meaning "tower": a reference to the form (''morph'') of the head in the type genus '' Pyrgomorpha'' and other genera. They may sometimes be known as "gaudy grasshoppers", due to the striking, often aposematic colouration of a number of genera; however many others are camouflaged or cryptic, including the genus '' Pyrgomorpha''.

Insect
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Pneumoroidea
The Pneumoridae are a family of nocturnal short-horned grasshoppers in the order Orthoptera, commonly known as the bladder grasshoppers and the sole representative of the superfamily Pneumoroidea. Their centre of diversity is in southern Africa, but one species occurs as far north as South Sudan. Most adult males acquire an inflated abdomen, a specialization for amplified sound production, which is likely its primary function. Most genera display striking sexual dimorphism, and several species exhibit a dual male phenotype. Description They are nocturnal, specialized herbivores which (with few exceptions) are endemic to coastal regions of southern Africa. The smallest species is '' Pneumoracris browni'' occurring in the Succulent Karoo ecoregion, while the largest is the wide-ranging Afromontane forest species, '' Physophorina livingstoni''. Sexual dimorphism The body length of adult males vary from 11.5 to 68.0 mm, and that of females from 22.0 to 107 mm. Males of a ...

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 ...
