With a wing span of up to 11 cm, the emperor dragonfly takes the title of largest dragonfly in these parts. In both the English and the Latin name (Anax imperator) we find the word emperor, and behaving like an emperor is exactly what this animal does. It can stay in the air for hours at a time, claims and defends its own territory; and all those who dare trespass on this domain are swiftly banished or devoured.
