Core Viewpoint - The article highlights the seasonal increase in cases of "winged sulfur" or blister beetle dermatitis as temperatures rise, emphasizing the importance of avoiding contact with the beetle to prevent skin reactions [1][2]. Group 1: Health Risks and Symptoms - Blister beetles contain a toxic compound called cantharidin, which can cause dermatitis characterized by linear red spots, pustules, and even ulceration upon contact with skin [2][6]. - The peak incidence of blister beetle dermatitis typically occurs from June to September, with a notable increase in cases during this period [2]. Group 2: Prevention and Treatment - Medical professionals advise against swatting the beetle, as this can increase the affected skin area by 3 to 5 times. Instead, it is recommended to gently brush or blow the beetle away [4][6]. - In case of contact, it is suggested to use adhesive tape to remove any remnants of the beetle and rinse the area with running water for 15 minutes, avoiding alcohol or other home remedies [6][8]. - For symptoms like redness and swelling, a 3% boric acid solution or 0.1% acridine solution can be used for wet compresses, while topical corticosteroids may help with itching [8]. Group 3: Environmental Considerations - Blister beetles thrive in warm, humid environments, particularly after rain or in areas with abundant vegetation, making it advisable to avoid such locations [12]. - Residents in areas with many trees and plants should ensure windows are properly screened to prevent beetles from entering homes, especially at night when they are attracted to light [9][14].

Core Viewpoint - The article discusses the rising incidence of injuries caused by the "flying sulfuric acid," known as the hidden winged insect, due to increased temperatures, leading to a significant rise in related skin conditions this year compared to last year [1][2]. Summary by Sections Incidence and Impact - As of April 20, a hospital in Wuhan reported over 200 cases of hidden winged insect dermatitis, with a single-day record of 20 cases on April 11, marking a 35% increase compared to the same period last year [1][2]. Characteristics of the Insect - The hidden winged insect contains strong acidic toxins throughout its body, which can cause severe skin reactions upon contact, including swelling, redness, and the formation of blisters or sores [6][9]. Treatment and Prevention - If the insect lands on the skin, it is advised to gently blow or shake it off rather than squashing it, which can release toxins [9]. In case of contact, washing the affected area with soap or a 4% baking soda solution is recommended to neutralize the toxins [11]. - Preventive measures include regular cleaning to avoid insect breeding, installing screens to block entry, and wearing long sleeves when outdoors [12][13].
