The insect that has appeared in large numbers at the Osaka Expo venue is a type of chironomid called <strong>Cricotopus sylvestris<\/strong>.

Chironomid midges are believed to spawn in brackish waters where freshwater and seawater mix. The Association has confirmed, based on previous on-site surveys by specialist operators, that the source of the large numbers of chironomid midges in the Expo site is the Water Plaza and the Sea of Connections.<\/p>\n<p style=\"text-align: right;\">\u5f15\u7528\uff1a<a href=\"https:\/\/www.expo2025.or.jp\/en\/news\/news-20250527-02\/\" target=\"_blank\" rel=\"noopener\">EXPO 2025<\/a><\/p>\n<\/blockquote>\n<div class=\"cardlink\"><a href=\"https:\/\/minnano-rakuraku.com\/contents\/en\/expo2025-null2-en-19333\/\"><div class=\"cardlink_thumbnail\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/minnano-rakuraku.com\/contents\/wp-content\/uploads\/2025\/04\/image-117-300x300.png\" alt=\"Expo 2025 Osaka: Yoichi Ochiai\u2019s \u201cnull2 (Nurunuru)\u201d Signature Pavilion \u2013 Concept, Highlights, and Reservation Guide\" width=\"300\" height=\"300\"><\/div><\/a><div class=\"cardlink_content\"><span class=\"cardlink_timestamp\">2025.04.25<\/span><div class=\"cardlink_title\"><a href=\"https:\/\/minnano-rakuraku.com\/contents\/en\/expo2025-null2-en-19333\/\">Expo 2025 Osaka: Yoichi Ochiai\u2019s \u201cnull2 (Nurunuru)\u201d Signature Pavilion \u2013 Concept, Highlights, and Reservation Guide<\/a><\/div><div class=\"cardlink_excerpt\">Expo 2025 Osaka, Kansai (2025 Japan International Exposition) finally opened on April 13, 2025.\r\n\r\nThe theme of Expo 2025 Osaka is &quot;Designing Fut...<\/div><\/div><div class=\"cardlink_footer\"><\/div><\/div>\n<h2>What is Cricotopus sylvestris?<\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/minnano-rakuraku.com\/contents\/wp-content\/uploads\/2025\/06\/\u30e6\u30b9\u30ea\u30ab.png\" alt=\"Clip art of chironomid\" width=\"300\" height=\"225\" class=\"aligncenter\" \/><\/p>\n<p><strong>Cricotopus sylvestris<\/strong> is <strong>a type of fly<\/strong> that lives in brackish water, where seawater and freshwater mix.<\/p>\n<p><strong>Chironomids are a type of fly.

But, with the help of experts and companies that make insect control products, we are developing new ways to deal with this.<\/p>\n<p>People often misunderstand these flies. They have emerged in large numbers, but <strong>they do not bite people<\/strong>. Therefore, <strong>there is no need to worry about infections or transmissible diseases<\/strong>.<\/p>\n<p>But there&#8217;s a small chance that insect carcasses could cause allergies or asthma if they get in your eyes or mouth or stick to your clothes. So, it&#8217;s important to take steps to control any insects that might be attracted to the area.<\/p>\n<p>If you don&#8217;t like bugs, it&#8217;s best to stay away from waterfront areas. Try to stick to areas with fewer insects, or visit before dusk when chironomids are more likely to appear.<\/p>\n<p>Take steps to control any insects and enjoy yourself at the Osaka Expo!<\/p>\n<p>&nbsp;<\/p>\n<div class=\"cardlink\"><a href=\"https:\/\/minnano-rakuraku.com\/contents\/en\/osaka-expo-pavilion-en-17280\/\"><div class=\"cardlink_thumbnail\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/minnano-rakuraku.com\/contents\/wp-content\/uploads\/2025\/03\/\u30ce\u30e2\u306e\u56fd_\u5927\u962a\u4e07\u535a-300x300.webp\" alt=\"Which pavilion is the most popular at the Osaka Expo?
