A rider is an insect that provides unquestionable help to a person

A rider is an insect that differs from othersrepresentatives of their class place of laying eggs. When the time comes for reproduction, the female searches for the victim. Having noticed a suitable larva, she thrusts the ovipositor into the victim's body and instantly lays an egg. One attempt is not enough - and she has to attack several times, sustaining an open dangerous battle, which a slow victim, as a rule, loses to a smart opponent.

Insect-rider can amaze and openlyliving larvae, and leading a hidden lifestyle, for example, in wood or stems. In such cases, the female ovipositor, like a drill, picks up an obstacle. Some riders lay eggs not on the body of the victim, but on its surface. The larva, which appeared on the light, firmly holding, gnaws the outer shell of the victim and feeds on its juices.

A rider is an insect with a thin body, with an elongatedabdomen, with a long needle-like ovipositor at the end. The thickness of the ovipositor is comparable to horsehair. Inside it there are three filiform villi, with the wiggling of which the egg moves. A distinctive feature is the long antennae with which the surface probes and the slightest vibration is detected by the rider (insect). The photo shows it well.

Interestingly behaves Dinocampus coccinellae(an insect rider with a size of about 4 mm, belonging to the family of braconids) parasitizing on a seven-point ladybug. The laid egg begins to develop in the body of the victim. Larva from the egg

leaves in a few days.She begins to eat fatty and connective tissues, without affecting the internal organs of the cow, which as if does not notice the changes that have occurred. This lasts about 25 days.

When it's time to leave the body of the carrier,the larva of the rider gnaws the nerves that go to the limbs of the cow, so that she can not escape. Having got out of the body, the larva is located between the legs of its "canned", i.e. under her body, interlace the cocoon, which develops further. It's amazing, but the ladybird has been alive all this time. Pupa grows about a week, and then leaves the cocoon. Scientists at the University of Montreal have proved that in every fourth case the carrier remains alive, moreover, after this incident, he returns to the ordinary way of life.

Currently, about 40 thousand kinds of riders are known. Despite the multiplicity, people rarely encounter them. This is due to the fact that

habitats insects choose poorly,calm. They vary in size (from a few millimeters to 5 cm), by habitat, color and behavior. Their victims are also different. They can be asparagus tweezers, bedbugs, cotton weevils, apple fruit boats and many others. But no matter how he behaved and wherever the rider lived, the insect always provides his offspring with food. Considering that the overwhelming majority of their victims are insect pests of agricultural crops, ruining them, riders provide undoubted assistance to a person, preventing their spread. It is on this unusual method of reproduction that the biological method of combating many pests is based.
