Ms. Yuan came to Changsha from other places to travel, when playing in a park, she suddenly felt a small bug parked on her neck, she patted it casually, and saw that it was a small black worm that was killed. The next morning, Ms. Yuan woke up and felt burning and painful in her head and neck, looked in the mirror and found a large red spot on her neck, and hurried to the dermatology department of Changsha Central Hospital (Changsha Central Hospital affiliated to the University of South China).

20-year-old Xiao Wang and his classmates went to the suburbs to play together, and when they sat on the grass to rest, they suddenly felt an itch in the back of their neck. The classmate saw a small black flying insect resting on her neck and quickly slapped it with her hand. Not long after the insect was knocked out, Xiao Wang felt that the back of his neck was burning and painful, and his skin was red, and he was also diagnosed with cryptoptera dermatitis.
Zhang Li, chief physician of the Department of Dermatology of Changsha Central Hospital (Changsha Central Hospital Affiliated to the University of South China), introduced that Cryptoptera is a small black flying insect, which is more active in summer and autumn, often flies around the lights at night, and after the insect body that stays on the skin is slapped, the strong acidic venom in its body will cause dermatitis. Cryptoptera dermatitis is characterized by the local appearance of striped, flaky, or dotted clusters of edematous erythema on the skin, with dense papules, blisters, or pustules, which may be secondary to erosions, crusting, and epidermal necrosis, with itching, burning, and burning sensations. If it occurs in areas such as the eyelids, there is also significant swelling. Patients with large erythema may have symptoms such as fever, dizziness, and regional lymphadenopathy.
"Cryptoptera does not bite, causing dermatitis because the skin is exposed to a strong acidic venom in its body. Therefore, never use your hands to slap cryptoptera that rests on your skin. Zhang Li suggested that it is best to wear long clothes and trousers when playing in green, apply anti-mosquito water on exposed parts of the body, and do not stay in grass and bushes for a long time. If symptoms associated with Cryptoptera dermatitis develop, you should seek immediate medical attention to avoid causing a bacterial infection.
