Acrididae
Acrididae are the predominant family of grasshoppers, comprising some 10,000 of the 11,000 species of the entire suborder Caelifera. The Acrididae are best known because all locusts (swarming grasshoppers) are of the Acrididae. The subfamily Oedipodinae is sometimes classified as a distinct family Oedipodidae in the superfamily Acridoidea. Acrididae grasshoppers are characterized by relatively short and stout antennae (so they may be called "short-horned grasshoppers"Borror, Donald J. and Richard E. White. ''A Field Guide to the Insects of America North of Mexico.'' Houghton Mifflin, Boston: 1970. p. 78), and tympanal organ, tympana on the side of the first abdominal segment. Subfamilies The ''Orthoptera Species File'' (September 2021) lists the following subfamilies of Acrididae. The numbers of genera and species are approximate and may change over time. * Acridinae MacLeay, 1821 (140 genera, 470 species), Worldwide: temperate and tropical * Calliptaminae Jacobson, 1905 ...

Locust
Locusts (derived from the Latin ''locusta'', locust or lobster) 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 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) when their populat ...

Grasshopper
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are amongst what are possibly the most ancient living groups 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. Their front legs are shorter and used for grasping food. As hemimetabolous insects, they do not undergo complete metamorphosis; they hatch from an egg into a Nymph (biology), 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, a change in light intensity is perceived in the simple eyes (ocelli). At high population densities and under certain environmental conditions, som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euryphyminae
The Euryphyminae are a subfamily of grasshoppers in the family Acrididae Acrididae are the predominant family of grasshoppers, comprising some 10,000 of the 11,000 species of the entire suborder Caelifera. The Acrididae are best known because all locusts (swarming grasshoppers) are of the Acrididae. The subfamily Oedi ..., based on the type genus '' Euryphymus'' and may be called "agile grasshoppers"; it was erected by Vitaly Michailovitsh Dirsh in 1956. Species have been recorded from parts of sub-Saharan Africa including Madagascar (but the distribution may be incomplete).

Acridoidea
Acridoidea is the largest superfamily of grasshoppers in the order Orthoptera with over 11,000 species found on every continent except Antarctica. Classification ''Orthoptera Species File'' includes the following families: * Acrididae MacLeay, 1821 * Dericorythidae Jacobson & Bianchi, 1905 * Lathiceridae Dirsh, 1954 * Lentulidae Dirsh, 1956 * Lithidiidae Dirsh, 1961 * Ommexechidae Bolívar, 1884 * Pamphagidae Burmeister, 1840 * Pamphagodidae Bolívar, 1884 * Pyrgacrididae Kevan, 1974 * Romaleidae Pictet & Saussure, 1887 * Tristiridae Rehn, 1906 Chromosomes Among the families Acrididae, Ommexechidae and Romaleidae there is reported to be chromosomal stability with a high frequency of species harbouring diploid number (2n) of 23♂/24♀ chromosomes. In species of Acrididae and Romaleidae it is common to have acrocentric chromosomes with a fundamental number (FN), i.e. number of chromosome arms, of 23♂/24♀. However, chromosomal rearrangements are frequently found as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
