Locusts 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.
The Pentatomoidea are a superfamily of insects in the suborder Heteroptera of the order Hemiptera. As hemipterans, they possess a common arrangement of sucking mouthparts. The roughly 7000 species under Pentatomoidea are divided into 21 families. Among these are the stink bugs and shield bugs, jewel bugs, giant shield bugs, and burrower bugs.
The Rocky Mountain locust is an extinct species of grasshopper that ranged through the western half of the United States and some western portions of Canada with large numbers seen until the end of the 19th century. Sightings often placed their swarms in numbers far larger than any other locust species, with one famous sighting in 1875 estimated at 198,000 square miles (510,000 km2) in size, weighing 27.5 million tons and consisting of some 12.5 trillion insects, the greatest concentration of animals ever speculatively guessed, according to Guinness World Records.
Grasshoppers are a group of insects belonging to the suborder Caelifera. They are amongst what are possibly the most ancient living groups of chewing herbivorous insects, dating back to the early Triassic around 250 million years ago.
The Thunder Basin National Grassland is located in northeastern Wyoming in the Powder River Basin between the Big Horn Mountains and the Black Hills. The Grassland ranges in elevation from 3,600 to 5,200 feet, and the climate is semi-arid. The Grassland provides opportunities for recreation, including hiking, sightseeing, hunting, and fishing. There are no developed campgrounds; however, camping is allowed. Land patterns are very complex because of the intermingled federal, state, and private lands.
The Asilidae are the robber fly family, also called assassin flies. They are powerfully built, bristly flies with a short, stout proboscis enclosing the sharp, sucking hypopharynx. The name "robber flies" reflects their expert predatory habits; they feed mainly or exclusively on other insects and, as a rule, they wait in ambush and catch their prey in flight.
The differential grasshopper is a species of grasshopper belonging to the genus Melanoplus. It is found throughout northern Mexico, the central United States and southern Ontario, Canada. It is considered a pest over most of its range.
Entomological warfare (EW) is a type of biological warfare that uses insects to interrupt supply lines by damaging crops, or to directly harm enemy combatants and civilian populations. There have been several programs which have attempted to institute this methodology; however, there has been limited application of entomological warfare against military or civilian targets, Japan being the only state known to have verifiably implemented the method against another state, namely the Chinese during World War II. However, EW was used more widely in antiquity, in order to repel sieges or cause economic harm to states. Research into EW was conducted during both World War II and the Cold War by numerous states such as the Soviet Union, United States, Germany and Canada. There have also been suggestions that it could be implemented by non-state actors in a form of bioterrorism. Under the Biological and Toxic Weapons Convention of 1972, use of insects to administer agents or toxins for hostile purposes is deemed to be against international law.
Six-Legged Soldiers: Using Insects as Weapons of War is a nonfiction scientific warfare book written by author and University of Wyoming professor, Jeffrey A. Lockwood. Published in 2008 by Oxford University Press, the book explores the history of bioterrorism, entomological warfare, biological warfare, and the prevention of agro-terrorism from the earliest times to modern threats. Lockwood, an entomologist, preceded this book with Ethical issues in biological control (1997) and Locust: The devastating rise and mysterious disappearance of the insect that shaped the American frontier (2004), among others.
The Fauna of Saskatchewan include several diverse land and aquatic animal species. From the multiplicity of invertebrates and vertebrates, two have been chosen as symbols of Saskatchewan. Cenozoic vertebrate fossils reveal the geological evolution of the interior plains and its prehistoric biogeography. Today, Saskatchewan's ecosystems range from the sub-arctic tundra of the Canadian Shield in north Saskatchewan to aspen parkland, the Mid-Continental Canadian forests in the centre of the province and grassland prairie. Fauna inhabit areas unique to their own specific and varied breeding, foraging and nesting requirements. With a large land and water area, and small population density, the ecoregions of Saskatchewan provide important habitat for many animals, both endangered and not. Naturalists observing wildlife have enumerated shrinking and growing wildlife populations. They advocate programs and methods to preserve or re-introduce endangered species and identify programs of control for outbreaks of wildlife populations. A broad diversity of wildlife habitats are preserved as parks and reserves protecting the feeding and breeding grounds of protected and indigenous fauna of Saskatchewan.
Schistocerca americana is a species of grasshopper in the family Acrididae known commonly as the American grasshopper and American bird grasshopper. It is native to North America, where it occurs in the eastern United States, Mexico, and the Bahamas. Occasional, localized outbreaks of this grasshopper occur, and it is often referred to as a locust, though it lacks the true swarming form of its congener, the desert locust.
Orphulella speciosa, commonly known as the slant-faced pasture grasshopper, is a species of short-horned grasshopper in the family Acrididae.
Melanoplus chiricahuae, the Chiricahua short-wing grasshopper, is a species of spur-throated grasshopper in the family Acrididae. It is found in North America.
Melanoplus stonei, known generally as the Stone's grasshopper or Stone's locust, is a species of spur-throated grasshopper in the family Acrididae. It is found in North America.
Melanoplus militaris, the military spur-throat grasshopper, is a species of spur-throated grasshopper in the family Acrididae. It is found in North America.
Melanoplus frigidus, known generally as the Nordic mountain grasshopper or narrow-winged locust, is a species of spur-throated grasshopper in the family Acrididae. It is found in Europe and Northern Asia.
Monteithiella humeralis, commonly known as the pittosporum shield bug is a species of herbivorous shield bug native to Australia and introduced in New Zealand. As its common name suggests, it is most commonly observed feeding on Pittosporum plants.
