Anabrus Simplex
The Mormon cricket (''Anabrus simplex'') is a large insect native to western North America in rangelands dominated by sagebrush and forbs. ''Anabrus'' is a genus in the Tettigoniinae, shield-backed katydid subfamily in the Tettigoniidae family, commonly called katydids, bush crickets, and previously "long-horned grasshoppers." Its common name, "Mormon cricket," is a misnomer: Cricket (insect), true crickets are of the family Gryllidae. The Mormon cricket takes its common name from the prominent role it played in the miracle of the gulls after the Mormon settlers in Utah had encountered them while pushing westward. Although flightless, the Mormon cricket may travel up to two kilometres a day in its Swarm behavior, swarming phase during which it may be a serious agricultural pest and sometimes a traffic hazard. Description Mormon crickets can grow to almost in length. Individuals vary in coloration: the overall color may be black, brown, red, purple or green. The pronotum, the D ...

Samuel Stehman Haldeman
Samuel Stehman Haldeman (August 12, 1812 – September 10, 1880) was an American natural history, naturalist and philologist. During a long and varied career he studied, published, and lectured on geology, conchology, entomology and philology. He once confided, "I never pursue one branch of science more than ten years, but lay it aside and go into new fields." Early life and education Haldeman was born in Locust Grove (Bainbridge, Pennsylvania), Locust Grove, Pennsylvania on August 12, 1812, the oldest of seven children of Henry Haldeman and Frances Stehman Haldeman. Locust Grove was the family estate on the Susquehanna River, twenty miles below Harrisburg, Pennsylvania, Harrisburg. His father was a prosperous businessman and his mother was an accomplished musician who died when Haldeman was twelve years old. In 1826, he was sent to Harrisburg to attend school at the Classical Academy, run by John M. Keagy. After two years in the academy, he enrolled at Dickinson College where his ...

Dorsal (anatomy)
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek language, Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and anatomical axes, axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graminoid
In botany and ecology, a graminoid refers to a herbaceous plant with a grass-like morphology, i.e., elongated culms with long, blade-like leaves. They are contrasted with forbs, herbaceous plants without grass-like features. The plants most often referred to include the families Poaceae (grasses in the strict sense), Cyperaceae (sedges), and Juncaceae (rushes). These are not closely related but belong to different clades in the order Poales. The grasses (Poaceae) are by far the largest family, with some 12,000 species. Ecology Besides their similar morphology, graminoids share a widespread occurrence and often dominance in open habitats such as grasslands or marshes. They can, however, also be found in the understory of forests. Sedges and rushes tend to prefer wetter habitats than grasses.

Swarm Behavior
Swarm behaviour, or swarming, is a collective behaviour exhibited by entities, particularly animals, of similar size which aggregate together, perhaps milling about the same spot or perhaps moving ''en masse'' or migrating in some direction. It is a highly interdisciplinary topic. As a term, ''swarming'' is applied particularly to insects, but can also be applied to any other entity or animal that exhibits swarm behaviour. The term '' flocking'' or ''murmuration'' can refer specifically to swarm behaviour in birds, ''herding'' to refer to swarm behaviour in tetrapods, and ''shoaling'' or ''schooling'' to refer to swarm behaviour in fish. Phytoplankton also gather in huge swarms called ''blooms'', although these organisms are algae and are not self-propelled the way animals are. By extension, the term "swarm" is applied also to inanimate entities which exhibit parallel behaviours, as in a robot swarm, an earthquake swarm, or a swarm of stars.

Mormon Crickets In Nevada
Mormons are a religious and cultural group related to Mormonism, the principal branch of the Latter Day Saint movement started by Joseph Smith in upstate New York during the 1820s. After Smith's death in 1844, the movement split into several groups following different leaders; the majority followed Brigham Young, while smaller groups followed Joseph Smith III, Sidney Rigdon, and James Strang. Most of these smaller groups eventually merged into the Community of Christ, and the term ''Mormon'' typically refers to members of the Church of Jesus Christ of Latter-day Saints (LDS Church), as today, this branch is far larger than all the others combined. People who identify as Mormons may also be independently religious, secular, and non-practicing or belong to other denominations. Since 2018, the LDS Church has expressed the desire that its followers be referred to as "members of The Church of Jesus Christ of Latter-day Saints", or more simply as "Latter-day Saints".

Nuptial Gift (animal Behavior)
Formally, a nuptial gift is a material presentation to a recipient by a donor during or in relation to sexual intercourse that is not simply gametes in order to improve the reproductive fitness of the donor. Often, such a gift will improve the fitness of the recipient as well. This definition implies neutral gifts, costly gifts and beneficial gifts regarding the fitness of the recipient. Nuptial gifting is at the intersection of sexual selection, nutritional ecology, and life history theory, creating a link between the three. Edible and inedible nuptial gifts Many nuptial gifts are a source of nutrition for the recipient. In many species of animals, including birds, insects, and spiders, this takes the form of a food item that is transferred from a male to a female just prior to copulation. This is a behavior known as courtship feeding. Inedible tokens may include items such as a fragment of leaf or twig, a seed tuft, or a silk balloon. How gifts are received There are three ...

Spermatophore
A spermatophore, from Ancient Greek σπέρμα (''spérma''), meaning "seed", and -φόρος (''-phóros''), meaning "bearing", 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 arachnid Arachnids are arthro ...

Instar
An instar (, from the Latin '' īnstar'' 'form, likeness') is a developmental stage of arthropods, such as insects, which occurs between each moult (''ecdysis'') until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or ny ...

Nymph (biology)
In biology, a nymph (from Ancient Greek wikt:νύμφα, νύμφα ''nūmphē'' meaning "bride") is the juvenile (organism), juvenile form of some invertebrates, particularly insects, which undergoes gradual metamorphosis (biology), metamorphosis (hemimetabolism) before reaching its adult stage. Unlike a typical larva, a nymph's overall form already resembles that of the adult, except for a lack of wings (in winged species) and the emergence of genitalia. In addition, while a nymph ecdysis, moults, it never enters a pupal stage. Instead, the final moult results in an adult insect. Nymphs undergo multiple stages of development called instars. Taxa with nymph stages Many species of Arthropod, arthropods have nymph stages. This includes the insect orders such as Orthoptera (cricket (insect), crickets, grasshoppers and locusts), Hemiptera (cicadas, shield bugs, Whitefly, whiteflies, aphids, leafhoppers, froghoppers, treehoppers), mayfly, mayflies, termites, cockroaches, mantises, ...

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 ...

Stinger
A stinger (or sting) is a sharp organ found in various animals (typically insects and other arthropods) capable of injecting venom, usually by piercing the epidermis of another animal. An insect sting is complicated by its introduction of venom, although not all stings are venomous. Bites, which can introduce saliva as well as additional pathogens and diseases, are often confused with stings, and vice versa. Specific components of venom are believed to give rise to an allergic reaction, which in turn produces skin lesions that may vary from a small itching weal, or slightly elevated area of the skin, to large areas of inflamed skin covered by vesicles and crusted lesions. Stinging insects produce a painful swelling of the skin, the severity of the lesion varying according to the location of the sting, the identity of the insect and the sensitivity of the subject. Many species of bees and wasps have two poison glands, one gland secreting a toxin in which formic acid is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
