In the last few warm days of the year, dragonflies are making the most of it. Here are two common darters, but what are they doing? 

That's the brightly-coloured male on the right, followed by the female. When they're mating, he seizes her by the back of the head, and after the deed they fly around like a tiny helicopter tandem. They fly together as she flicks her tail into the water to deposit the fertilised eggs.
