That was unusual due to the rarity of observing the species, as well as its status as an endangered insect.<\/p>\n<p>On L\u0101na\u02bbi City alone, <strong>there have only been two prior record sightings<\/strong> of Blackburn\u2019s Sphinx Moth since 2009, including 2025 when a single caterpillar was reported.<\/p>\n<p>Collectively, these sightings suggest that there continues to be a viable population of Blackburn\u2019s Sphinx Moth on L\u0101na\u02bbi.<\/p>\n<p>However, the news didn\u2019t stop here. During May and June, <strong>the same crews discovered Blackburn\u2019s Sphinx Moth caterpillars<\/strong> in Halawa Valley and Kalae on the island of Moloka\u02bbi.<\/p>\n<p>Those were the first recorded instances of the species being found on the island of Moloka\u02bbi since the 1940s.<\/p>\n<p>Observing multiple sites for caterpillars suggests that the <strong>moth had likely remained present but undiscovered<\/strong>.<\/p>\n<h2>Blackburn&#8217;s Sphinx Moth: a species resisting extinction<\/h2>\n<p>Blackburn\u2019s Sphinx Moth used to exist throughout most of the main islands in Hawaii. Native insects in Hawaii continually experience pressures from <a href=\"https:\/\/www.ecoportal.net\/en\/florida-woman-boa-hurricane-andrew\/29016\/\">habitat destruction, predation, and non-native competitors<\/a>.<\/p>\n<p>At the close of the 1970s, <strong>scientists concluded that the species was extinct<\/strong>. In 1984, the species was rediscovered on the eastern side of Maui.<\/p>\n<p>Afterward, additional populations were located on Kaho\u02bbolawe and the Big Island.<\/p>\n<p>Other islands had seemingly eradicated the moth entirely. <strong>Therefore, these recent finds made them noteworthy<\/strong>.<\/p>\n<p>Officials with <a href=\"https:\/\/dlnr.hawaii.gov\/blog\/2026\/07\/17\/nr26-85\/\" target=\"_blank\" rel=\"noopener\">Hawaii&#8217;s Department of Land and Natural Resources<\/a> referred to the discoveries as surprising yet exciting.<\/p>\n<p>They demonstrated that <strong>endangered insect populations can remain intact for<\/strong> long periods of time without documented confirmations.<\/p>\n<p>The newly recorded sightings also updated researchers&#8217; knowledge of where the moth currently exists, providing state wildlife officials with insight to inform future monitoring and recovery efforts.<\/p>\n<p><strong>This ultimately led to an inquiry<\/strong> as to what this elusive insect was like.<\/p>\n<h2>Hawaii\u2019s giant, fast-moving native pollinator<\/h2>\n<p>The moth is commonly referred to as Blackburn\u2019s Sphinx Moth. It is regarded as one of Hawaii\u2019s larger native insects.<\/p>\n<p><strong>Adult moths possess a wingspan nearing five inches<\/strong>.<\/p>\n<p>Many describe flying patterns similar to that of hummingbirds. The moth has the ability to hover while consuming nectar from flowers.<\/p>\n<p>The brown and gray coloration <strong>allows it to easily blend into its surroundings<\/strong>.<\/p>\n<p>Due to its size and camouflage capabilities, spotting this moth is typically uncommon.<\/p>\n<p><strong>Similar characteristics apply to its larvae<\/strong>.<\/p>\n<p>Each caterpillar features a horn projecting from its posterior area. The horn is characteristic of many sphinx moth species.<\/p>\n<p>Sphinx moth caterpillars <strong>consume only specific host plant material<\/strong>.<\/p>\n<p>Adult moths are able to obtain nutrition by consuming nectar from flowers as they travel between various food sources, helping to <a href=\"https:\/\/www.ecoportal.net\/en\/roughly-7-000-panels-fill-eleven\/32091\/\">pollinate native plants along the way<\/a>.<\/p>\n<h3>A new direction for island conservation<\/h3>\n<p>Prior to its discovery on East Maui in 1984, Blackburn\u2019s Sphinx Moth <strong>was believed to exist across all<\/strong> major Hawaiian Islands.<\/p>\n<p>Recent discoveries indicate that it continues to inhabit areas where officials believed it had completely disappeared.<\/p>\n<p>Confirming that these populations persist on L\u0101na\u02bbi and Moloka\u02bbi changes the outlook for island conservation. <span style=\"font-size: inherit;\">It gives wildlife crews concrete target zones to <\/span><a style=\"font-size: inherit;\" href=\"https:\/\/www.ecoportal.net\/en\/red-wolves-return-north-carolina\/29686\/\">focus host-plant restoration and habitat protection<\/a><span style=\"font-size: inherit;\"> moving forward.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Wildlife workers searching for rare native insects in Hawaii did not expect to find an endangered moth surviving on islands where it was thought to have vanished.
