What's Happening?
The Blackburn’s sphinx moth and the Hawaiian damselfly, two endangered insect species, have been rediscovered on Hawaiian islands where they were previously thought to be extinct. The Department of Land and Natural Resources' Division of Forestry and Wildlife
(DOFAW) staff found new populations of these species on Lana‘i, Moloka‘i, and Hawai‘i Island. The Blackburn’s sphinx moth, once widespread across the Hawaiian Islands, was believed extinct in the late 1970s but was rediscovered in 1984 on East Maui. Recent sightings in Lana‘i City and Moloka‘i suggest a sustained population. Similarly, the Hawaiian damselfly was spotted on Hawai‘i Island for the first time since 1923. These discoveries are significant as they indicate potential recovery for these species, which have been declining due to habitat loss and competition with non-native species.
Why It's Important?
The rediscovery of these endangered species is crucial for biodiversity conservation in Hawaii. It highlights the resilience of native species and the importance of ongoing conservation efforts. The presence of these insects can help maintain ecological balance, as they play roles in pollination and as part of the food web. The findings also underscore the need for continued habitat protection and restoration to support these and other native species. The success of these efforts could serve as a model for similar conservation initiatives globally, emphasizing the importance of preserving native habitats and addressing threats from invasive species.
