Calliptamus italicus, the Italian locust, is a species of 'short-horned grasshopper' belonging to the family Acrididae, subfamily Calliptaminae.

Contents

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.

Distribution and habitat

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]

Description

Young Calliptamus italicus - esemplare giovane - 01.JPG
Young

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]

Ecology

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]

<span class="mw-page-title-main">Migratory locust</span> Species of grasshopper

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.

<span class="mw-page-title-main">Bandwing</span> Subfamily of grasshoppers

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:

<span class="mw-page-title-main">Red locust</span> Species of grasshopper

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.

<span class="mw-page-title-main">Wart-biter</span> Species of insect

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.

<i>Dociostaurus maroccanus</i> Species of grasshopper

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.

<i>Locusta migratoria manilensis</i> Subspecies of locust

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.
