Locusts are a group of certain 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.
Cymbopogon, also known as lemongrass, barbed wire grass, silky heads, Cochin grass, Malabar grass, oily heads or fever grass, is a genus of Asian, African, Australian, and tropical island plants in the grass family. Some species are commonly cultivated as culinary and medicinal herbs because of their scent, resembling that of lemons . The name cymbopogon derives from the Greek words kymbe and pogon "which mean [that] in most species, the hairy spikelets project from boat-shaped spathes."
Glareolidae is a family of birds in the wader suborder Charadrii. It contains two distinct groups, the pratincoles and the coursers. The atypical Egyptian plover, traditionally placed in this family, is now known to be only distantly related.
The black-winged red bishop, formerly known in southern Africa as the fire-crowned bishop, is a resident breeding bird species in tropical Africa from Senegal to Sudan and south to Angola, Tanzania, Zimbabwe and Mozambique.
The desert locust is a species of locust, a periodically swarming, short-horned grasshopper in the family Acrididae. They are found mainly in Africa, through Arabia and West Asia, and extending into parts of South Asia. During population surge years, they may extend into parts of western Spain. The desert locust shows periodic changes in its body form and can change, in response to environmental conditions, over generations, from a solitary, shorter-winged, highly fecund, nonmigratory form to a gregarious, long-winged, and migratory phase in which they may travel long distances into new areas. In some years, they may thus form locust plagues, invading new areas, where they may consume all vegetation including crops, and at other times, they may live unnoticed in small numbers.
The antlions are a group of about 2,000 species of insect in the family Myrmeleontidae, known for the fiercely predatory habits of their larvae, which in many species dig pits to trap passing ants or other prey. The adult insects are less well known, due to their relatively short lifespans compared to the larvae. Adults mostly fly at dusk or after dark, and may be mistakenly identified as dragonflies or damselflies; they are sometimes known as antlion lacewings. In North America, the larvae are sometimes referred to as doodlebugs because of the strange marks they leave in the sand.
The migratory locust is the most widespread locust species, and the only species in the genus Locusta. It occurs throughout Africa, Asia, Australia and New Zealand. It used to be common in Europe but has now become rare there. Because of the vast geographic area it occupies, which comprises many different ecological zones, numerous subspecies have been described. However, not all experts agree on the validity of some of these subspecies.
The red locust is a large grasshopper species found in sub-Saharan Africa. Its name refers to the colour of its hind wings. It is sometimes called the criquet nomade in French, due to its nomadic movements in the dry season. When it forms swarms, it is described as a locust.
The Indian desert jird or Indian desert gerbil is a species of jird found mainly in the Thar Desert in India. Jirds are closely related to gerbils.
The Brachyceran family Vermileonidae is a small family of uncertain affinities and unusual biology. It includes fewer than 80 described species, most of them rare and with restricted distribution, in 10 genera. Historically the vermileonids had been regarded as belonging to the family Rhagionidae, possibly in a subfamily Vermileoninae. Their biology and morphology is so markedly distinct from the main Rhagionidae sensu stricto however, that the placement as a separate family has been widely accepted.
The wattled starling is a nomadic resident bird in eastern and southern Africa. It is a species of grassland, open woodland, and cultivation.
The freckled nightjar is a species of nightjar in the family Caprimulgidae. It has a wide yet patchy distribution throughout the Afrotropics.
The southern red bishop or red bishop is a small passerine bird belonging to the bishop and widowbird genus Euplectes in the weaver family, the Ploceidae. It is common in wetlands and grassland in Africa south of the Equator. North of the Equator, it is replaced by the northern red bishop or orange bishop which was formerly regarded as a subspecies of this species.
The Australian plague locust is a native Australian insect in the family Acrididae, and a significant agricultural pest.
The Senegalese grasshopper is a medium-sized grasshopper species found in the Sahel region of Africa, the Canary Islands, Cape Verde Islands, and West Asia. Although not called a locust in English, this species shows gregarious behaviour and some morphological change on crowding. In many parts of the Sahel, this species may cause greater year-on-year crop damage than better-known locusts, attacking crops such as the pearl millet.
The brown locust is a medium-sized small locust species in the monotypic genus Locustana. It is found in Southern Africa and shows classic gregarious behaviour with phase polymorphism on crowding.
Dociostaurus maroccanus, commonly known as the Moroccan locust, is a grasshopper in the insect family Acrididae. It is found in northern Africa, southern and eastern Europe and western Asia. It lives a solitary existence but in some years its numbers increase sharply, and it becomes gregarious and congregates to form swarms which can cause devastation in agricultural areas. The species was first described by Carl Peter Thunberg in 1815.
Locusta migratoria migratorioides, commonly known as the African migratory locust, is a subspecies of the migratory locust in the family Acrididae.
Banyutus lethalis is an African antlion. It is proposed as the mimic for the gregarious African antlion, Hagenomyia tristis, but can be identified based on the longer antennae and single dorsal stripe on the pterothorax. Both species fly gregariously through long grass and can be collected together. The larvae of B. lethalis are non-pit building, whereas those of H. tristis are pit-builders.
Schistocerca cancellata is a species of locust in the subfamily Cyrtacanthacridinae. It is the major swarming species in subtropical South America. This species shows typical locust phase polymorphism. Solitarious nymphs are green, but gregarious ones are yellow with a black pattern. There are morphological differences between solitarious and gregarious adults. For many years the two phases were believed to be different species and the gregarious form was mistakenly identified as S. paranensis. The solitary phase is found in South America between 18°S and 35°S. Plagues originate in a desert and semi-desert zona permanente in NW Argentina, SE Bolivia and W Paraguay, when good rains allow successful breeding, followed by gregarisation. Swarms of gregarious adults may then migrate into crop growing regions.
