A drop of rain does not kill a mosquito because he knows it, "to merge"

In the new study, scientists have tried to understand the basic principles of interaction with a drop of mosquito. To work, they used a high-speed camera that was filming the flight of a mosquito in the installation where a special pump to simulate rain.

According to scientists, the average linear dimensions of the mosquito are about 3 mm with a mass of 2 milligrams. In turn, the diameter of the droplet of water is up to 8 mm at a weight of up to 100 milligrams. The vertical component of the drop speed in up to 9 meters per second. Drop falls into the mosquito on average once every 20 seconds.

The researchers were able to determine that the drop in contact with the presser foot mosquito tumbles sideways, almost without changing direction. Thus in contact with the body of the mosquito drops within a short period of time moves with the drop down to a distance of about 60 millimeters, and then leaves it.

Scientists say that the energy drops is enough to kill a mosquito when hit, if he is on a solid surface, but meeting the air passes to the mosquito almost without consequences (in this case, however, the mosquito is experiencing an overload of 100 g, but they did not harm him ). Physicists attribute this to the fact that the motion, together with a drop to minimize the transfer of energy from the insect drops - the speed drops almost unchanged after a meeting with the mosquito.
