Core Points - The article discusses the emergence of the "hidden wing bug" in Shandong, highlighting its potential danger and providing a safety manual for the public [2][4]. Identification and Characteristics - The hidden wing bug measures 0.6-0.8 cm in length, resembling a large ant, with a black head and abdomen, orange-yellow thorax and legs, and inconspicuous wings [4]. - It prefers light and moisture, often found in rice fields, grasslands, and forests, and is attracted to light at night [4]. Behavior and Effects - The bug does not bite but releases a strong acidic venom (pH 1-2, comparable to concentrated sulfuric acid) when crushed [6]. - The venom causes delayed reactions: redness and burning on the first day, increased swelling and pain on the second day, and possible yellow pus and severe itching on the third day [7][8]. Prevention and Response - To avoid contact, individuals are advised to gently blow or use a card to remove the bug instead of swatting it [9][10]. - In case of contact, immediate washing with plenty of water or soap is recommended to neutralize the venom [11]. - For initial symptoms, treatments include applying calamine lotion for itching and using saline solution for blisters [12]. - If severe symptoms occur, such as pus or intense pain, seeking medical attention is crucial [13]. Preventive Measures - Maintain cleanliness by clearing debris and weeds around homes to reduce habitats for the bug [14]. - Close windows and curtains at night to minimize light attraction [14]. - Wear long sleeves and pants when outdoors to protect skin [14]. - Use insecticides containing "permethrin" or "pyrethroids" in key areas to create a protective barrier [14].

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].
