Brachaspis
''Brachaspis'' is a genus of grasshoppers belonging to the family Acrididae. The species of this genus are found in New Zealand. In 2023 all species in this genus were moved to the genus '' Sigaus''.

Brachaspis Robustus
''Sigaus robustus'' is a New Zealand species of grasshopper classified as Threatened: Nationally Endangered. It is restricted to open stony habitat of the Mackenzie Basin of the South Island. Although a grasshopper, it is a poor jumper, relying on camouflage to hide from predators. It is threatened by introduced mammals such as stoats, hedgehogs, and rats. The New Zealand entomologist Tara Murray told '' North & South'' magazine in 2019: “They can actually jump, they just don’t land very well. On a hot day, an adult male can jump up to 1.5m, multiple times. Females are bulkier, so they don’t jump as far. These grasshoppers freeze as a first defence. If they do jump, it often ends as a back flop, belly flop or general ‘thock’ on the ground.” Species description ''Sigaus robustus'' is extremely well camouflaged, often relying on visual crypsis as passive defense against predation. It is also sexually dimorphic; adult males have a body length of 18–22 mm (0.71� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachaspis Nivalis
''Sigaus nivalis'', is an alpine short-horned grasshopper, Endemism, endemic to the South Island of New Zealand. ''Sigaus nivalis'' is brachypterous and flightless, therefore they travel by hopping. They bask during the day so need open habitat. Taxonomy/history 'Sigaus' means silent and 'nivalis' means of the snow, so the name translates as the Quiet snow grasshopper. The species was first reported and described by Frederick Hutton (scientist), Captain Frederick Wollaston Hutton from the Aoraki / Mount Cook, Mount Cook area and Marlborough Region, Marlborough in 1897, but was put in the genus ''Pezotettix'' with some synonyms at that time.Hutton, F.W. (1897).The Grasshoppers and Locusts of New Zealand and the Kermadec Islands. ''Proceedings and Transactions of the New Zealand Institute'' 30: 135–150. In 1898, Hutton proposed a new genus ''"Brachaspis"'' (from its short and broad sternal shield) and put in ''B. nivalis''.Hutton, F.W. (1898). ''Proceedings and Transactions of ...

Brachaspis Collinus
The Green Rock-hopper grasshopper, ''Sigaus collinus'' is an alpine species of short-horned grasshopper in the family Acrididae. It is found in New Zealand in the mountains of northern South Island, above the tree line and as high as 2000 m asl. In New Zealand alpine grasshoppers can freeze solid at any time of the year and are alive when they thaw out when temperatures rise. ''Sigaus collinus'' is flightless and adults are relative large (females 32 mm), and common amongst scree and tussock. Although widespread in 2020, about 97% of the habitat of the green rock-hopper grasshopper will be lost due to global warming by 2070. The species is variable in colour; most individuals are green with yellow markings, but some are olive-grey. In the Kaikoura ranges (Mt Luxford) ''S. collinus'' hybridises with ''S. nivalis'', but elsewhere the two species are well differentiated. An endemic species of mite (''Erythrites jacksoni'') is an ectoparasite of this grasshopper. References ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catantopinae
The subfamily Catantopinae is a group of insects classified under family Acrididae. Genera such as '' Macrotona'' may sometimes called "spur-throated grasshoppers", but that name is also used for grasshoppers from other subfamilies, including the genus ''Melanoplus'' from the Melanoplinae. Indeed, the delimitation of these two subfamilies needs restudy: the Podismini for example are sometimes placed here, sometimes in the Melanoplinae.

Grasshoppers
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. Und ...

Acrididae
The AcrididaeMacLeay WS (1821) ''Horae Entomologicae or Essays on the Annulose Animals'' 2 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, 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 (12 genera, 90 species), Africa, Europe, Asia # Caryandinae Yin & Liu, 1987 (3 genera, 100 species), Afric ...
