Calliptamus italicus, the Italian locust, is a species of 'short-horned grasshopper' belonging to the family Acrididae, subfamily Calliptaminae.
This species is native of the steppes of Central Asia, but it is also present in most of Europe, in the eastern Palearctic realm, in North Africa, and in the Near East.
Calliptamus italicus is found in Western Europe and Central Asia. [1] Its range extends from North Africa and the countries bordering the Mediterranean Sea to Central Europe, Central Asia, Mongolia and western Siberia. [2] These grasshoppers can be encountered from July through October. It thrives in warm dry habitats with sparse vegetation cover such as grasslands and rocky steppes, old quarries, gravel pits, rock-strewn areas beside rivers, sand dunes and fallow land. [3]
Calliptamus italicus is a medium-sized grasshopper characterized by a significant sexual dimorphism. The adult males grow up to 14–26 millimetres (0.55–1.02 in) long, while females reach 21–40 millimetres (0.83–1.57 in) of length. This species is quite variable in size and colour. The basic coloration of the body varies from gray to brownish-reddish. The wings have a characteristic reddish or pinkish coloration, better visible when the insect is in flight. Quite evident is the dilating membrane ('pallium') of the subgenital plate of males. [3]
Calliptamus italicus is a polyphagous species, able to feed upon various wild plants, but also on crops, especially legumes. Alfalfa (Medicago sativa) is among the species preferred by juveniles, but there have been reported sporadic cases of infestation on grains and grapevine. It feeds on a variety of plants in the families Asteraceae, Chenopodiaceae and Poaceae. [2]
Their life cycle lasts one year. The egg-laying takes place in late August - early September, usually in rocky areas exposed to the south. The female lays eggs in the soil within an ootheca that can hold 25 to 55 eggs wrapped in a spongy secretion. The appearance of the larvae takes place in May–June; the first adults appear in July.
In certain circumstances this species may develop a tendency to gregariousness with formation of very numerous aggregates, potentially harmful to crops. It normally occurs in low densities in undisturbed sparse grassland but disappears when the land is cultivated. It occurs in high densities in uncultivated land that is invaded by Artemisia , and on overgrazed pastures with weeds and bare ground. Under these conditions it can become gregarious and form locust swarms. After the breakup of the USSR in 1991, much agricultural land was left uncultivated. This gave ideal conditions for the Italian locust to breed and build up in numbers, and Kazakhstan suffered a devastating locust plague between 1998 and 2001. [4]
The following subspecies proposed in the past are no longer accepted. They are currently included in the nominal subspecies.
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.
Bandwings, or band-winged grasshoppers, are the subfamily Oedipodinae of grasshoppers classified under the family Acrididae. They have a worldwide distribution and were originally elevated to full family status as the Oedipodidae. Many species primarily inhabit xeric weedy fields, and some are considered to be important locusts:
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 wart-biter is a bush-cricket in the family Tettigoniidae. Its common and scientific names derive from the eighteenth-century Swedish practice of allowing the crickets to nibble at warts to remove them.
The blue-winged grasshopper, Oedipoda caerulescens, is a grasshopper in the genus Oedipoda.
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.
Arcyptera fusca, the large banded grasshopper, is a species of 'short-horned grasshoppers' belonging to the family Acrididae subfamily Gomphocerinae.
Calliptamus siciliae, commonly known as the pygmy pincer grasshopper, is a species of short-horned grasshoppers belonging to the family Acrididae subfamily Calliptaminae.
Oedipoda germanica, sometimes known as the "red-winged grasshopper", is a species of short-horned grasshoppers belonging to the family Acrididae subfamily Oedipodinae.
Podisma pedestris is a species of 'short-horned grasshoppers' belonging to the family Acrididae subfamily Melanoplinae.
Dactylotum bicolor, also known as the rainbow grasshopper, painted grasshopper, or the barber pole grasshopper, is a species of grasshopper in the family Acrididae. It is native to the United States, Canada and northern Mexico and exhibits aposematism. It was first described by the German entomologist Toussaint de Charpentier in 1843.
Aularches miliaris is a grasshopper species of the monotypic genus Aularches, belonging to the family Pyrgomorphidae. A native of South and Southeast Asia, the bright warning colours of this fairly large grasshopper keep away predators and their defense when disturbed includes the ejection of a toxic foam.
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.
Valanga nigricornis, the Javanese grasshopper, is a species of grasshopper in the subfamily Cyrtacanthacridinae of the family Acrididae. It is found in southeastern Asia, the type location being Singapore. It was first described by the German zoologist Hermann Burmeister in 1838. There are more than twenty subspecies, most of which are endemic to different island groups; the subspecies V. nigricornis nigricornis is the type for the genus Valanga.
Locusta migratoria manilensis, commonly known as the Oriental migratory locust, is a subspecies of the migratory locust in the family Acrididae. It is sufficiently different in size and structure from the African migratory locust to be considered a distinct subspecies of the migratory locust. It is found in southeastern Asia and is an important agricultural pest in the region. It is normally a solitary insect but when conditions are suitable, it enters into a gregarious phase when the young form into bands which move together and the adults into swarms. Although outbreaks may have recently been fewer in number and size because of changes in agricultural practices and better locust detection, the insects remain active as crop pests and the potential for outbreaks is still present.
Anacridium moestum, the camouflaged tree locust, is a species of grasshopper belonging to the family Acrididae, that is native to Africa south of the equator. It is similar in appearance to the Southern African desert locust, Schistocerca gregaria flavicentris. It is likewise brownish, large and slender, but mostly arboreal in its habits.
Calliptamus is a genus of grasshoppers in the family Acrididae. Species of Calliptamus are found in Africa and the northern Palearctic realm through to Japan.
Calliptamus barbarus is a species of short-horned grasshopper in the family Acrididae. It is found in the Palearctic.
Cyrtacanthacris tatarica, the brown-spotted locust, is a species of bird grasshopper in the family Acrididae. It is found in the Afrotropics and Indomalaya.
