Curiously Isolated Hairstreak
Satyrium curiosolus
Satyrium curiosolus, also known as curiously isolated hairstreak, is a species of butterfly in the family Lycaenidae that was first described in 2025. It is an isolated species found only on Blakiston Fan in Waterton Lakes National Park, Alberta, Canada. Long considered an isolated population of the half-moon hairstreak, genomic and ecological studies revealed it to be a distinct species that has likely been separated from its closest relatives for more than 40,000 years.
