Atlas of the European Dragonflies and Damselflies

Of the four European Emperor species, the Blue Emperor is easily the commonest and most widespread; only in Scandinavia is it still rare. Anax imperator is a large dragonfly and a formidable hunter, which regularly preys on smaller dragonflies. Its most distinguishing features include the male's striking light-blue abdomen (usually pale brownish green in the female, although quite a few of our photographs are of females with brown-and-blue abdomens) and the apple-green thorax. The female Anax imperator oviposits unguarded by the male - see photographs below.
