Some species of mosquitoes don't feed on human blood
As soon as they see a mosquito, most people's reaction is to quickly "smash" it to avoid being sucked in blood or "revenge" for being sucked in blood. But few people know that it is possible that you have "slaughtered" wrongly. In fact, only female mosquitoes like to suck blood, not all mosquitoes feed on human blood "preference". There are other species of mosquitoes such as snow mosquitoes, snow mosquitoes, and midges,... that don't suck human blood but are often unjustly "slaughtered" by humans.
For example, to your normal eyes, midges look very similar to the mosquitoes that bite you every day. But in fact, Midge mosquitoes do not like to bite people and do not transmit diseases, they are completely harmless to humans. The snow mosquito is also a weak insect, they eat almost nothing or sometimes only eat the larvae of other mosquito species, they maintain life by drinking water in the snow.
