For those living in the Arctic, especially those scientific workers who conduct deep field investigations, some insects are daunting and quite scary. For example, Arctic mosquitoes often gather in large swarms, like a moving dark cloud, rushing in and biting in turn. If not strictly protected, they can often kill people. There is also a kind of black fly, which has a very sensitive sense of smell. It can smell the scent of people from a long distance, and then it flies in in groups, buzzing, and stalks the target like a desperado. Even if you wear thick clothes, it will not help, because its steel-needle-like mouth can even bite through the old skin on the feet, and then pierce deeply into the flesh, sucking blood, and at the same time spitting out a poisonous juice that makes people feel uncomfortable. You have a big bump on your body that is painful, swollen, or even ulcerated. The scene is quite scary.
