Lindenia tetraphylla, or bladetail, is a species of dragonfly from the family Gomphidae found in Central and Southwest Asia, and parts of the Mediterranean. It is the only extant representative of the monotypic genus Lindenia. A fossil relative, †Lindenia heeri Boderau, Engel, Stössel & Nel, 2024, is known from the Middle Miocene-aged Oehningen fossil site of Germany.
Adults are easily recognizable due to their impressive body size with 69–80 mm length, the leaf-shaped flaps on the bottom side of the abdomen tip which are unique in European species, and wing venation. The flaps give the narrow and long abdomen club-shaped appearance. Basic color is pale yellow with dark brown or black markings of variable size. The pterostigma is also similarly colored. In south Croatia and Montenegro, it is possible to observe completely black individuals, which is probably a consequence of them developing in cold springs.
The adults fly in the summer, from the end of May until August. Bladetail breeds in larger lakes and larger, slowly flowing rivers. Adults tend to wander far from where they hatched, and may colonize new bodies of water, such as... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Bladetail is recorded against all the insects logged in Rostov-on-Don (5 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
