Tristiridae
The Tristiridae are a family of grasshoppers, in the Orthoptera: suborder Caelifera. Species in this family can be found in the Americas The Americas, which are sometimes collectively called America, are a landmass comprising the totality of North and South America. The Americas make up most of the land in Earth's Western Hemisphere and comprise the New World. Along with th .... Genera The ''Orthoptera Species File'' (31 March 2010) lists: * Atacamacridinae Carbonell & A. Mesa, 1972 *** '' Atacamacris'' Carbonell & Mesa, 1972 * Tristirinae Rehn, 1906 ** Elasmoderini Cigliano, 1989 *** '' Elasmoderus'' Saussure, 1 ...

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. Thi ...

Acridoidea
Acridoidea is the largest superfamily of grasshoppers in the order Orthoptera with 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 deviations from the standar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Under ...

With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.
