Eunota striga, commonly known as the Elusive Tiger , is a rarely encountered to coastal of the southeastern United States. The species has earned its through its strictly activity pattern—apparently nobody has observed it during daylight hours. It is reliably detected only through its attraction to ultraviolet "blacklights," making it one of the most specialized tiger beetles in North America in terms of survey methodology. The species occurs in salt marshes, mud flats, and openings in coastal pine forest, with the "Road to Nowhere" site in Florida's Dixie County representing one of the most reliable locations for encountering this species.
