THE REAL WORLD

The real Autumn darter

Facts about the real animal.

It emerges at lowland ponds and marshes in early summer and spends the summer in the mountains. In autumn it comes back down to the lowlands.

Right after emerging, its chest is yellow and its abdomen orange. In autumn the male's whole abdomen turns red.

It is a typical 'red dragonfly'. The male and female stay joined together while laying eggs in the water.

In autumn, the female turns red just on the upper side of her abdomen.
