Big camaras were, of course, common to everyone. If such a "helicopter" flies into the house, many are frightened, considering them very dangerous, although of all types of insects these are the most harmless. So who are these monsters?
The largest camar on the planet is a caramor, or long-legged mosquito. It is found in forests with high humidity. She feels equally well both in temperate climates and in North Africa. The karamor itself is essentially harmless in nature, since it does not bite animals or humans. Basically we see males that feed on nectar. But his larvae, eating plant food, can cause serious harm to crops.
Big camar - karamor - is not so gigantic in size. His body is from 2 mm to 6 cm long, there are specimens reaching 10 cm. But due to the fact that this insect has unusually long legs, it seems that it is much larger.
Another big camar is a dergun. It got its name because it often twitches its front legs.
People even breed this insect, or rather, its larvae - bloodworms that go to feed aquarium fish. In nature, a large camar-dergun lays eggs in wetlands, where, buried in silt, they develop, turning into larvae. If you collect water and soil from the bottom of a standing lake, then filter and rinse, you can always find a certain amount of bloodworms. He goes to feed not only domestic fish, but also the inhabitants of water bodies.
The mosquito-dergun lays eggs in a special translucent jelly-like cocoon. It is different in shape: round, oblong, long as a cord. It depends on where the female is going to attach it, so that it does not get washed away by the current, and the larvae could get to the bottom and have time to burrow before they become food for fish. The larva emerging from the egg is colorless, greenish and reddish in color as it grows after molting.
The bloodworm is adapted for life in water. He can swim, wriggling his whole body like a snake. The breathing process occurs in two ways. He has a respiratory organ, similar to gills and located in the tail of the body, he breathes with it when it turns into a pupa, in addition, he is able to absorb air throughout the surface. The larva has a red color due to the fact that hemoglobin is part of the blood.
Despite the apparent primitiveness, bloodworms are a very interesting creature. He lives and develops at the bottom of the lakes, but he moves not just like that, but in special tubes, which he himself builds from silt, sand grains and pebbles, connecting them with saliva. The larva sits in the tube, periodically sticking out the “head”, that part of the body where the mouth is located, digs and searches for nutrient particles. All this is a way to survive to the state of an adult. If you do not take precautions, you can become easy prey for the inhabitants of the lake.
The bloodworm makes a pupa in the same place, in the tube, exposing the peculiar gills that absorb oxygen. And a big camar-dergun comes to the surface with the help of air. The process resembles the rise of a bathyscaphe, the chrysalis rises upward, under pressure it collapses, and the dergun, spreading its wings, takes off.
