quiet summer evening, near lakes or rivers, and maybe on the footpath in the woods you probably watched the swarming mosquitoes.Incidentally, the randomly moving mass consists only of male mosquito.In science, described the swarms, which have dimensions of up to 5 m wide and 7 m in height.
the male mosquito mating holds
All swarm of mosquitoes waiting for the next will be female.This method requires a large space pairing is called "evrigamiya", ie at the time of mating swarm.Males, in an amount up to 100 000 individuals are pounded, making the sound of wings, which attract females.The first one who manages to grab a curious lady, had entered into a swarm, fertilize it in the air.
But the city produces the male mosquito mating without digging.This is called "stenogamiya" and allows urban insect produce offspring in the cellars, which usually have limited size.
How wakes bloodlust
ready to mate the male finds the female mosquito by using antennae covered mikrovoloskami, they serve it to human ears, able to capture the sounds of the female.Squeak mature female mosquito is more active than the sounds produced by young individuals.
From the moment when there was fertilization, the female mosquito starts in desperate need of blood.Without it, it can not lay eggs and bring the full-fledged offspring.Therefore, the female looks for an object to feed.Hungry fertilized individual can feel the presence of a warm-blooded object at a distance of 3 km!And in one go bloodthirsty "lady" can drink serving more than their initial weight.
Why is the male mosquito - a vegetarian?
Perhaps, for anybody not news that we only females bite.And without exception, involve male mosquito species that feed on nectar, pollen or not eating.For example, as chironomids, who live only 3 days and did not even have a mouth opening.And though they itch as nasty as their ladies bloodsuckers, but the man did not cause any harm.
way, if for some reason the female mosquito can not find the blood, it becomes a forced vegetarian.True, and the ability to lay eggs, she also loses.
protein found in human or animal blood, invigorates komariha to lay eggs that can produce a healthy mosquitoes.The male mosquito, whose photos you see in this article, does not need such a solid-fueled.It is enough carbohydrates, and to enjoy life.
And what are they for?
Take the time to talk: "bite hurt, squeak disgusting - they interfere with life!" Well, yes, to some extent in the way.Mosquitoes - males and females - as if created to annoy people and animals.Yes, and the disease is transferred!But the disappearance of this important link in the natural food chain would lead to incredible disasters.
For example, in areas with harsh climatic conditions sometimes only mosquito larvae are catering for a huge number of birds.The disappearance of a mosquito - the death of birds ... And then, perhaps, do not need to tell.In addition, their little bodies, these insects carry a number of trace elements necessary for the growth and blades of grass and giant trees that arguments about the need for a mosquito in our world moving away to the side.In nature, there is nothing superfluous!
