Beetle weevil

Sometimes in a handful of hazelnuts will turn out to be wormy. Smack it out - it bitterens, instead of the nucleolus, there are some stubs. And it happens, you will see the tenant: a white legless larva with a yellow head is a weevil beetle. The same with acorns.

And it happens, you will see the tenant: a white legless larva with a yellow head is a weevil beetle

Everything begins at the beginning of summer, when a weevil beetle emerges from the ground: a small bug, dressed in a spotted reddish felt. But he is not that remarkable. The nose ... Oh, what a long nose! Slightly shorter than the beetle itself. Thin, slightly thicker horsehair. It turns out that at the very tip of the nose-proboscis is the mouth. In the middle of the proboscis cranial tendrils are attached, at the base - eyes. The head of the weevil beetle is strongly extended forward. This denoted the name of such beetles: their common name is the elephant ("trunk") or weevil ("nose"). There are a lot of them - different kinds of weevils of weevils about forty-five thousand.

The shell of the hazelnut is strong, inside - a stock of delicious food. Good housing for children beetle weevil - white larvae. But there is no entrance for this "home". A nut can be bad, and it can also happen that the "house" is already occupied. So the beetle borer crawls on nuts, looking for the right one. When the nut is selected, it is necessary to make a hole. The weevil beetle has jaws: two chitinous plates. They are tiny, but strong. Two hours later, a hole appears on the nut. Finally, the fossa becomes a hole.

Having pulled out their nut of proboscis, the female of the weevil beetle turns to a hole back. Pulls out a thin tube from the end of the abdomen, which is lowered into the hole, and an egg is slipped along the tube-ovipositor into the nut...

After a while, the larva of the weevil beetle is removed from the egg. It takes about a month, and the larva grows adult. Then it starts moving inside the nut. Crawls closer to its base, where the shell is not so dense and starts to gnaw the shell. Here she gnawed a round window in her shell. The window is small: just beyond the head of the larva of the weevil beetle. But the head is almost three times as big as the torso. And yet a thick larva leaves through a narrow door. How?

The trunk of the larva of the weevil beetle is very soft. In this - the solution. She can put a head in it, clad in a strong chitin sheath, protected like a strong horn box. The larva has no legs. She can not rest against the walls of her dwelling. Yes, and she does not need to do this. The larva bends, straightens, bends again. The larva of the weevil beetle is as if pulled in the middle: outside - the head with an inflated thoracic part, in the nut - a fat abdomen at the end. It looks like a strange eight: the upper circle is almost round, a wide waist and a long lower oval half. And here the front part of the trunk begins to stretch. Soft body, squeezing in a narrow window, gradually squeezes through it.

The larva of the weevil beetle does not linger for a moment on the threshold of his house. Slipping on the shell and falling to the ground, she begins to dig the ground.

Buried in a small cave, the larva of the weevil beetle will spend the winter there. Wintering inside the nut seems to be calmer than in the ground. In the nut, the larva is protected by a strong shell, and in the ground it lies naked. You can winter in a nut, and in the spring, before turning into a pupa, you can get out. Good and simple. Simply - yes, but there is not much good here. You can not winter in a walnut. A dangerous place is nuts on the ground. They are a delicious prey for mice and voles, the badger and bear will not refuse them. Nuts pick up, a heap of fallen leaves, landslides. The larva of the weevil beetle will die: her house-nut will attract enemies.

In the spring, the larva of the weevil beetle turns into a pupa. A few weeks pass, and a long-nosed weevil beetle is selected.
