The abundance of butterflies in the US slumped 22% between 2000 and 2020, the new analysis of more than 76,000 mostly regional surveys, published in Science, found. For every five butterflies fluttering daintily around at the start of the century, just four remain today.<\/p>\n<p>The new research drew together more than 30 scientists to pore over reams of data detailing sightings of butterflies across the US. More than 340 species had enough information on them to ascertain their population trends. This work didn\u2019t identify exact causes for the declines, although scientists have been clear that habitat loss, pesticide use and the climate crisis are the main culprits for insect losses, with other problems such as light pollution affecting fireflies and moths in particular.<\/p>\n<p>For butterflies, the threats vary by region \u2013 in the more arid US south-west, drought worsened by global heating is causing butterflies to desiccate and for host plants to wither. In the agricultural heartland of the midwest, meanwhile, the rampant use of insecticides on fields is the leading cause of butterfly mortality.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.theguardian.com\/us-news\/2025\/mar\/06\/declining-butterfly-populations\">Guardian<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/5-684\/\">Butterfly population in US shrinking by 22% over last 20 years, study shows<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[3761,575,2005,574],"class_list":["post-138091","post","type-post","status-publish","format-standard","hentry","category-news","tag-butterfly","tag-environmental-news-en","tag-population","tag-us"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/138091","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/comments?post=138091"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/138091\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=138091"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=138091"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=138091"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
