Lilypad Whiteface (Leucorrhinia caudalis)
Denmark
Status: Bern Convention. EU Habitat Directive IV. In Denmark known since the 18th century from several localities on Sjælland, but died out during the first half of the 20th century, last confirmed in 1910. Recently however, 2018, a single male was discovered on Falster, and in 2023, several males and females were seen at Horreby Lyng, also Falster, giving promise to the re-introduction of the species. None were seen in 2024 and only two in 2025, but being an up to 3-years species 2026 is the year to have eyes on! Rare in Norway but common in both Sweden and Finland.
