Acrotylus insubricus


RED-WINGES GRASSHOPPER

Kingdom: Animalia.
Phylum: Arthropoda.
Class: Insecta.
Order: Orthoptera.
Suborder: Caelifera.
Superfamily: Acridoidea.
Family: Acrididae.
Subfamilia: Oedipodinae.
Genre: Acrotylus.
Species: Acrotylus insubricus.

This is the most common and widespread of the three Iberian species of the genus Acrotylus. The black spot of the hind wing is small and well separated from the edge of the wing and the wing tip is stained dark.

It is found in dry, sunny and in the Iberian Peninsula is often seen between April and November.
It can be found almost anywhere in our land, always in low and medium altitudes.
They measure between 3 and 8 cm in length as adults.
The young resemble adults but lack wings.
You may experience seasonal changes in color and are green at certain times and other red or brown.
Grasshoppers are very close relatives of crickets and the males produce sounds similar to these.
Females also produce sounds of various species.

Females lay eggs in holes drilled into the ground in the fall.
The eggs hatch in spring and the young reach maturity in July or August.
When a non-migratory grasshopper like this is played too fast for the available food resources, and experiences of migration becomes major changes in its shape.



Family Features

It belongs to the family of the locust (Acrididae) whose main features are:

They are known locally as lobsters or grasshopper , are a family of Orthoptera bugger characterized by its ease to migrate from one place to another and, in certain circumstances, reproduce very rapidly reaching devastating pests to be able to destroy the vegetation of large areas of land.

Lobster is called each of the Members of large groups of grasshoppers. Grasshoppers usually do not fly much, despite that they have wings. Only when large groups of individuals together in the same species release pheromones to enable appropriate development in the migratory behavior and further growth of the wings and thus spread to other territories, preventing intraspecific competition for food.

Lobsters have long hind legs for jumping and chewing mouthparts and eat leaves. Its activity is mainly nocturnal and use their antennae and eyes to explore the field.

Like many insects, grasshoppers have two pairs of wings (although some species are unable to fly). When the insect is at rest, its strong protective forewings aa serve their delicate hind wings, which are below those folded like a fan. The hind wings may have bright colors to produce a flash of color when the insect jumps in the air (this show will ahyuda to confuse predators). Some lobsters can close their wings in mid-air and falling through the air in order to escape their enemies.

The young lobsters are unable to fly until they become adults. Change color when they are grouped, acquiring a shade of orange, bright yellow and black.

Generally, lobsters produce only a new generation per year. After mating, the female lays eggs in small groups of the ground or in vegetation. Some species produce a special foam progtegar eggs. When they hatch, the nymphs of insects look like miniature adults. Move the cuticle between 5 and 15 vesca before reaching maturity.

To skip the lobster, has its long, slender hind tibia of its very close to the body near the center of gravity. The large muscles of the thickest part of the leg (femur) are connected with the head of the tibia. When these muscles contract, straightening the leg throwing the insect into the air.

In order to get as high as possible, lobster puts your body in streamlined position, with closed wings, and legs stiff and folded under the body. The muscles of his legs are a thousand times more powerful than an equal weight of human muscle, so jumping locusts can reach a height of 50 cm, equivalent to ten times the length of his body, also can jump twenty times its length.

Once the lobster has jumped as high as possible, opens its two pairs of wings all you can, keep the legs fully strained, the hind wings bent upward and curved to the previous capture as much air as possible and begin to beat them quickly, propelling with increasing speed. Take the hind legs skin-tight, aerodynamic position, whereas when you go to rest, put the past tense deployed and ready to withstand the impact of your body where it rests. In the air the lobster moves its wings to the unbeatable seafront speed of 20 wing beats per second, reaching a speed of 3.7 km / h, reaching over 100 km travel per day.

Bonjour Lucas,
Je sais que les sauterelles ne suscitent pas grand intérêt, mais je suis toujours heureuse de voir présentée une espèce bien documentée et présentée. Une image simple et présentée avec une bonne netteté.
Merci!
Anne
