Sting of a bug of plavunets
Zhuk-plavunets is a widespread inhabitant of fresh reservoirs with a large number of vegetation and other living creatures. Therefore everyone who is approached to such water sources can meet it. From features of a bug-plavuntsa it is possible to allocate his rather big sizes (about 3-5 cm), a convex surface and an oval form, existence of firm wings. He carries out the basis life cycle in water. Sometimes it can be seen and on the land near a reservoir. Bug-plavuntsa stings happen in water more often.
Even memories of a sting of a bug-plavuntsa cause fear in people who were exposed to its attack. The moment of a sting is felt, how sharp sudden pain. It remains and after the termination of direct contact with a bug. The sting reminds a skin puncture a sharp subject with localization of pain only in one place.

Sting of a bug of a strigun
Zhuk-strigun treats the insects living on the land. Has firm wings at the expense of what moves by air. Its appearance quite characteristic also corresponds to the name of this insect. The average sizes make 2,5 – 3 cm. The bug has black coloring and long moustaches. Its approach when flying is shown by a characteristic crash and hum. The bug-strigunets eats exclusively vegetable young escapes. Bites the person extremely seldom though contact with it happens repeatedly.
These bugs very often purposefully fall on the head to the person during flight. Thus the bug flies in hair, getting confused in them. The bug strigunets can bite the person only at his direct extraction from hair. Similar stings are absolutely safe and besides short-term morbidity cause nothing. Wounds after them superficial also begin to live independently. So, what to be afraid of these bugs, giving in to negative emotions and a panic, is not necessary.

Toxin gets on skin in attempt of the person to remove a bug from its surface. Thus it is crushed owing to the fragility. Kontaridin gets on skin and through microcracks extends in its depth. In such places in some hours peculiar abscesses with purulent allocations and formation of wounds are formed. On this background there can be also general reactions of immune system in the form of temperature increase of a body, the general weakness, headache nausea. If such toxin in a large number gets to intestines, it can cause death of the person. Therefore in the ancient time poison of a bug-naryvnika was used as toxic agent.
