More and more people went to the beach to play and fish in the summer, but many people were "recruited" at the beach, they were bitten by a mysterious bug, and the itch was incomparable. It is understood that this mysterious flying insect belongs to the midge class, commonly known as "small bite", midge flying speed and no rules, the body is smaller than the sesame seeds, because its trace is difficult to find, so it is often called "invisible".
Citizens are frequently bitten by mysterious insects at the beach
Not long ago, Ms. Li went to the beach in the morning to catch the sea, did not expect that the bare parts such as hands and legs were bitten into several bags, at first Ms. Li thought that she was bitten by mosquitoes, did not take it seriously, did not expect that the bitten part was extremely itchy. Ms. Li said that the area where she was bitten formed a red and swollen bag the size of a soybean grain, and there was a small blister on it, which was very different from ordinary mosquito bites. "The itch is particularly bad, I don't dare to scratch, it's not easy to be good, and it's not strong for a few days." Later, I asked about it, saying that this is not a mosquito bite, it should be bitten by a small insect on the seashore, what kind of bug is this? So powerful. Ms. Li said.
On August 2, the reporter came to the anti-wave dam between the fisherman's wharf and the stone trough to visit, and there were many people fishing on the dam that day, mentioning the biting bugs, and many anglers hated it, because they were deeply affected. "I thought it was a mosquito, but then I found out that it wasn't, it was a small black bug that could fly, it was particularly bad at biting people, it was really itchy, and it was particularly difficult to be good." "How many times have I been bitten, and I can't scratch the bag after biting, and every piece of it is red and swollen, and it is still out of the water." "I've been bitten by this bug, and now when I come fishing, no matter how hot it is, it's all long-sleeved, and it's spraying with dew."
The itch was unbearable for several days after being bitten
Mr. Sun, a citizen, told reporters that he stayed on the dam for a short time two days ago, suddenly felt a stinging pain coming from the bare part of the ankle, and finally found the black so-called "biting expert", they are smaller than sesame seeds, black, almost can not see the wings, the flight trajectory is hidden from time to time, and quietly.
After Mr. Sun was bitten, he did not appreciate its severity for the first few minutes. About half an hour later, the bite site appeared to itch, so scratching, did not want to scratch more and more itchy, it turned out that the ankle had been unconsciously bitten seven or eight times. That night, he slept until midnight, because the ankle was so itchy, he subconsciously scratched a few times, but he did not expect to scratch more and more itchy, and he did not sleep well. To this day, the pimples on his ankles continue to be red, swollen and itchy.
The "perpetrator" turned out to be a midge
What exactly is this biting little bug? The reporter interviewed Jiang Changyang, a professor at the School of Biology of Liaoning Normal University, who told reporters that this flying insect belongs to midges, commonly known as "small bites", and mainly breeds in dark and wet areas such as woods, weeds, and watersides. Midges are small, fast and irregular, and are commonly known as "invisible" because they are difficult to find.
The reporter learned that after being initially bitten by midges, it is often manifested as erythema, lumps, blisters and other symptoms, and the bite site is itchy or secondary infection, and the symptoms do not subside for several days, and the patient has to endure a lot of pain.
Jiang Changyang said that after being bitten by midges, there will be different degrees of symptoms due to different individual constitutions, at this time, it is necessary to apply some dermatitis ointment or syrup in time, and can also be rinsed with alkaline water such as sulfur soap, and remember not to scratch hard to avoid skin damage caused by other infections.
Liu Li, director of the Department of Traditional Chinese Medicine and Beauty of Dalian Dermatology Hospital, said that the current activity of various mosquitoes has soared, and the number of dermatitis patients due to insect bites has also increased recently. Liu Li reminded the public that once a bite papule occurs, do not scratch the affected area with your hands to avoid causing infection. Peninsula Morning News, 39 degrees video reporter Tong Liang
