Southern Festoon - Zerynthia polyxena
The Southern Festoon is a swallowtail butterfly belonging to the Papilionidae family. Its life cycle is closely aligned to the herbaceous plant Aristolochia clematitis, or European Birthwort, as sole fodder plant. (In German, this butterfly's common name is in fact "Osterluzeifalter", while the herb is called "Osterluzei".) The plant's poisonous substance is larval food and remains in the organism of the adult butterfly.
Great Capricorn Beetle - Cerambyx cerdo
With a body length of around 5cm, the Great Capricorn Beetle, one of the so-called Long-Horned beetles, is one of the largest native beetle species.
Stag Beetle - Lucanus cervus
The Stag Beetle is the largest beetle in the Donau-Auen National Park – and in all of Europe! There is a significant difference between males and females: the males have oversized "antlers" (like stags) which are really enlarged jaws, whereas the females are smaller overall and also much have smaller jaws without the "antlers".
Violet Oil Beetle - Meloe violaceus
The Violet Oil Beetle is a very conspicuous, slow-moving, and stout blister beetle (sometimes called oil beetle) which is metallic blue. It lacks the ability to fly but otherwise exhibits very interesting behaviour. The Violet Oil Beetle is the most poisonous animal in the wetlands!
Banded Demoiselle - Calopteryx splendens
A remarkable, butterfly-like flying dragonfly with metallic blue shimmering wing bars. In the Donau-Auen National Park, the Banded Demoiselle is most likely to be seen on slow-moving backwaters, if only in limited numbers.
Emperor Dragonfly - Anax imperator
This "Ruler of the Skies" above our waters is one of the largest among native dragonflies. On warm sunny days, the conspicuous males are usually on the wing and can fly for hours at a time. Within the National Park, the Emperor Dragonfly may be spotted more frequently in the Lobau than in other areas, where it is rarer.
