In recent news from Epoch Times on October 8, 2025, reports have emerged of hidden-winged insects appearing in various locations in Henan Province. In Luoyang, these insects have infested a construction site’s scaffolding, causing widespread concern. A young girl in Nanyang came into contact with the venom of these insects, resulting in severe swelling and ulceration on her neck that has persisted for over 20 days without healing. This incident has surged to the top of the trending searches. In addition, there have been numerous cases of people in Hebei, Shandong, and other areas being injured by the venom of these hidden-winged insects. Reports from Chinese media describe these insects as “flying sulfur.”
According to Extreme Eye News, on October 7, Mr. Duan from a rural village in Renqiu, Hebei, woke up with a slight red swelling on his neck, initially thinking it was a minor scratch. However, as his symptoms worsened, he visited the hospital on the 7th, where doctors diagnosed him with an infection from the venom of hidden-winged insects.
Ms. Li from Shandong similarly stated that many people in her area have been affected by the venom of these insects recently. Additionally, numerous netizens have shared their experiences of being affected.
Recently, hidden-winged insects have been reported in various locations in Henan Province. Mr. Lu, who works at a construction site in Luoyang, mentioned that the scaffolding and large screens on the site, reaching fifty meters high and dozens of meters long, were crawling with these insects. Furthermore, Ms. Wang from Nanyang shared that her four-year-old daughter accidentally came into contact with the venom of hidden-winged insects 25 days ago, resulting in a swollen and ulcerated wound on her neck that has scabbed over but not yet healed.
Since September, multiple media outlets in Henan Province have reported on citizens encountering these hidden-winged insects. According to a report from Luoyang Daily on September 18, residents in Luoyang have found these insects in their homes. The bodily fluids of hidden-winged insects are highly acidic, earning them the nickname “flying sulfur.” Several hospitals in the city have recently treated numerous cases of hidden-winged insect dermatitis.
In a report by Dahe News, it was revealed that the venom of the poisonous hidden-winged insects contains a highly acidic toxin known as hidden-winged insect toxin. This is a contact poison that, when in contact with the skin, causes hidden-winged insect dermatitis, leading to itching, stinging, and burning sensations, linear red rashes or blisters on the skin, scabbing, and scarring after healing. For a very small number of individuals with allergies, it may provoke more severe reactions.
