Cyphoderris
Hump-winged grigs are insects belonging to the genus ''Cyphoderris'', in the family Prophalangopsidae, and superfamily Grylloidea ( crickets). In modern times they are known only in northwestern North America and central Asia, but the fossil record indicates a wider distribution in the past. There are three species in North America: *''Cyphoderris buckelli'' - Buckell's grig *'' Cyphoderris monstrosa'' - Great grig *'' Cyphoderris strepitans'' - Sagebrush grig Hump-winged grigs are known for their unique mating habits. Males call at night by sitting on a tree trunk with their head down and emitting a short, high-pitched trill. When a female mounts the male, the male uses two hooks on its back to hold onto the underside of the female's abdomen while transfering spermatophore A spermatophore or sperm ampulla is a capsule or mass containing spermatozoa created by males of various animal species, especially salamanders and arthropods, and transferred in entirety to the female's ovip ...

Cyphoderris Monstrosa
''Cyphoderris monstrosa'', also known as the great grig, is a species of hump-winged grig in the family Prophalangopsidae The family Prophalangopsidae are insects belonging to the order Orthoptera. They are the only extant members of the superfamily Hagloidea. There is only one extant genus in North America, where they are known as grigs, four genera in Asia, an .... Though the fossil record shows at least 90 extinct species from this family, ''C. monstrosa'' is one of only 7 known species alive today. Morphology The species generally grow to about 20–30 mm in body length and approximately 1.5 grams in weight. Dorsally, these crickets have dark coloring, ranging from lighter hues of brown to black. Ventrally they are lighter in color, often being white or beige in color. This coloration likely evolved as a form of camouflage, helping the crickets blend in with the darker bark of coniferous trees, of which they spend a significant portion of their time on. Like many cric ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyphoderris Strepitans
''Cyphoderris strepitans'', the sagebrush cricket or sagebrush grig, is a one of only a few surviving species in the family Prophalangopsidae. Three of these species are in the genus ''Cyphoderris'' and all three are endemic to North America.Dodson, G.N., Morris, G.K., and Gwynne, D.T. (1983). Mating behavior of the primitive orthopteran genus ''Cyphoderris''. In Orthopteran mating systems: sexual competition in a diverse group of insects. Edited by D.T. Gwynne and G.K. Morris. Westview Press, Boulder, Colorado. pp. 305–318. ''C. strepitans'' name is from the Latin word 'strepitans' which means 'making a great noise', refers to their calling song during the mating season. Description Sagebrush crickets are robust, cold adapted grigs that are dark brown in colour with black markings and a cream coloured abdomen, known as a venter. They can grow between 17 and 26 cm and display sexual dimorphism with males having a pair of wings, while the females lack wings. The membranous ...

Prophalangopsidae
The family Prophalangopsidae are insects belonging to the order Orthoptera. They are the only extant members of the superfamily Hagloidea. There is only one extant genus in North America, where they are known as grigs, four genera in Asia, and many extinct genera (see below). The closest living relatives to the Prophalangopsidae are the family Tettigoniidae (katydids or bush-crickets), but the evolutionary split occurred more than 230 million years ago in the Permian. The female of the species consumes the wings of the male during mating. Haglidae is often used as a synonym of the family, but is used to refer to a distinct grouping of extinct hagloids by paleontologists. Subfamilies and genera The Orthoptera Species File lists the following: Archibald, Gu, and Mathewes (2022) removed the genera †'' Albertoilus'' and †'' Palaeorehnia'' from the family, moving them to a newly revised † Palaeorehniidae which they considered unplaced as to superfamily. * Cyphoderrinae Go ...

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 eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grylloidea
Grylloidea is the superfamily of insects, in the order Orthoptera, known as crickets. It includes the " true crickets", scaly crickets, wood crickets and other families, some only known from fossils. Grylloidea dates from the Triassic period and contains about 3,700 known living species in some 528 genera, as well as 43 extinct species and 27 extinct genera. Characteristics The features which distinguish crickets in the superfamily Grylloidea from other Ensiferans are long, thread-like antennae, three tarsal segments, slender tactile cerci at the tip of the abdomen and bulbous sensory bristles on the cerci. They are the only insects to share this combination of characteristics. The term cricket is popularly used for any cricket-like insect in the order Ensifera, being applied to the ant crickets, bush crickets (Tettigoniidae), Jerusalem crickets (''Stenopelmatus''), mole crickets, camel crickets and cave crickets (Rhaphidophoridae) and wētā (Anostostomatidae), and the re ...

Cricket (insect)
Crickets are orthopteran insects which are related to bush crickets, and, more distantly, to grasshoppers. In older literature, such as Imms,Imms AD, rev. Richards OW & Davies RG (1970) ''A General Textbook of Entomology'' 9th Ed. Methuen 886 pp. "crickets" were placed at the family level (''i.e.'' Gryllidae), but contemporary authorities including Otte now place them in the superfamily Grylloidea. The word has been used in combination to describe more distantly related taxa in the suborder Ensifera, such as king crickets and mole crickets. Crickets have mainly cylindrically-shaped bodies, round heads, and long antennae. Behind the head is a smooth, robust pronotum. The abdomen ends in a pair of long cerci; females have a long, cylindrical ovipositor. Diagnostic features include legs with 3-segmented tarsi; as with many Orthoptera, the hind legs have enlarged femora, providing power for jumping. The front wings are adapted as tough, leathery elytra, and some crickets ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spermatophore
A spermatophore or sperm ampulla is a capsule or mass containing spermatozoa created by males of various animal species, especially salamanders and arthropods, and transferred in entirety to the female's ovipore during reproduction. Spermatophores may additionally contain nourishment for the female, in which case it is called a nuptial gift, as in the instance of bush crickets. In the case of the toxic moth ''Utetheisa ornatrix'', the spermatophore includes sperm, nutrients, and pyrrolizidine alkaloids which prevent predation because it is poisonous to most organisms. However, in some species such as the Edith's checkerspot butterfly, the "gift" provides little nutrient value. The weight of the spermatophore transferred at mating has little effect on female reproductive output. Arthropods Spermatophores are the norm in arachnids and several soil arthropods. In various insects, such as bush crickets, the spermatophore is often surrounded by a proteinaceous spermatophylax. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
