Acridoidea is the largest superfamily of grasshoppers in the order Orthoptera with over 11,000 species found on every continent except Antarctica. [2]
Orthoptera Species File includes the following families: [2]
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. [3] [4] 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♀. [4] However, chromosomal rearrangements are frequently found as deviations from the standard acrocentric karyotype. In the subfamily Ommexechinae most species show a unique karyotype (2n = 23♂/24♀, FN = 25♂/26♀) due to the occurrence of a large autosomal pair (L1) with submetacentric morphology. [4] There is some support for 'Mesa's hypothesis' of an ancestral pericentric inversion in the ancestor of Ommexechinae to explain this karyotype variation. [5] [6] [4] [7]
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 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, and tympana on the side of the first abdominal segment.
The grasshopper subfamily Acridinae, sometimes called silent slant-faced grasshoppers, belong of the large family Acrididae in the Orthoptera: 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 caatinga vesper mouse is a rodent species in the family Cricetidae from South America. It is endemic to eastern Brazil, where it is found in open savanna (cerrado) and thorny scrub (caatinga) habitats. Its karyotype has 2n = 66 and FN = 68. It was formerly synonymized with C. callosus, but the latter has 2n = 50 and FN = 66. Karyologic analysis of C. expulsus has shown that the X chromosome is large and submetacentric while the Y chromosome is either acrocentric or submetacentric. Predators include the barn owl. Sexual dimorphism in shape and size occurs; the former is present mainly before the age of 20 days. Males are smaller before age 50 days and larger thereafter, which becomes less prominent after 200 days.
The African rice grasshopper, Hieroglyphus daganensis is a medium-sized grasshopper species found in the Sahel region. Although not called a locust in English, this species shows gregarious behaviour and some morphological change on crowding and may become a moderately important pest species for small-holder farmers in the region.
Acrida is a genus of grasshoppers in the family Acrididae. The genus contains around 40 species which are found in Africa, Europe, Asia, North America, Hawaii, and Australia. Insects of this genus are omnivorous and a well-known pest of many agricultural crops.
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. It was first described by the German entomologist Toussaint de Charpentier in 1843.
Acridini is a tribe of insects in the subfamily Acridinae, of the insect family Acrididae and are sometimes called "silent slant-faced grasshoppers". It was firstly described as Truxalis Conicus in 1781
Tropidacris is a Neotropical genus of grasshopper in the family Romaleidae. They are among the largest grasshoppers in the world by length and wingspan, reaching up to 14.5 cm (5.7 in) and 24 cm (9.4 in) respectively. They are variably colored in green, brown, black, reddish or yellowish, and have wings that usually are conspicuously blue or red in flight. The gregarious and flightless nymphs have bright aposematic colors and are presumed to be toxic; a researcher who tasted one noted that it was very bitter, similar to a monarch butterfly.
Phymateus aegrotus, sometimes called the blue bush locust or East African bush locust, is a pest species of grasshopper in the family Pyrgomorphidae. Unlike "locusts" the adults are not known to change their morphology on crowding, but at the hopper stage, marching behaviour of small bands may occur.
Anacridium moestum, the camouflaged tree locust, is a species of grasshopper belonging to the family Acrididae, that is native to Africa south of the equator. It is similar in appearance to the Southern African desert locust, Schistocerca gregaria flavicentris. It is likewise brownish, large and slender, but mostly arboreal in its habits.
Pamphagidae is a family of grasshoppers belonging to the superfamily Acridoidea. The species in this family can be found in Africa, Europe and Asia.
Xiphoceriana atrox is a species of grasshoppers belonging to the family Pamphagidae.
Acrididea including the Acridomorpha is an infraorder of insects that describe the grasshoppers 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, which placed the "short-horned grasshoppers" and locusts at the family level (Acrididae). The study of grasshopper species is called acridology.
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.
The Trigonopterygoidea are an insect superfamily in the Orthoptera: Caelifera. Sometimes described as leaf grasshoppers, American species in the Xyronotidae have also been called razor-backed bush-hoppers.
The Lathiceridae are a family of grasshoppers, in the Orthoptera: suborder Caelifera. Species in this family can be found in the desert regions of southern Africa where they resemble the stony ground on which they live. They are characterized by their apterous (wingless) bodies, which are dorsoventrally depressed and often excessively widened in the metathoracic region, giving them a spindle-like appearance. Their integument is sculptured and rugose, and their coloration varies from white to brown and purple, harmonizing with the color of the substratum on which they live.
The Ommexechidae are a family of grasshoppers, in the Orthoptera: suborder Caelifera. Species in this family can be found in the Americas.
The Hemiacridinae are a subfamily of Acrididae in the Orthoptera: Caelifera. Species can be found in Africa and Asia.
Phymateus karschi is a locust in the family Pyrgomorphidae.
