Hawker dragonflies need to warm themselves in the sunshine to fly in lower air temperatures. You have to see them land to spot them as they align themselves with the stems

Despite the poor weather the brief periods of sunshine brought out a few dragonflies. They are getting a bit tatty now following encounters with blackberry thorns etc., but worth a few outdoor images on-the-wing. It is really only possible when they hover for a moment - here two frames about 150mS apart as he drifted forward a little.

We saw this pair of Southern Hawker dragonflies land in this 'Wheel' configuration in a willow behind duck pond and spend 63 minutes hanging on there being blown around in the wind before finally parting in two stages.
The male is at the top using his tail clasper to hold the female behind the head. She brings her vulva opening up to the male to pick up the sperm. They were very determined - the wind was blowing them about from this position to almost horizontal.

About 3 minutes before separating she has had enough and drops into 'tandem'. Some species then go on to lay eggs in this configuration, but not these.

The moment of separation probably and she flew off we know not where. He flew off a few minutes later

This is a Hawker dragonfly - the largest type. In the words of an old TV documentary we saw a couple of weeks ago, it will kill and eat 'anything smaller than itself'! Our experts differ on whether this is a male or female.

The male Southern Hawker Dragonflies continue to patrol the pond in search of females. Here one is taking a rest in the sunshine on an otherwise cold day, hanging from the seed heads of one of the types of Mallow.

This a mid-sized pair of dragonflies in the 'wheel' position in which they mate. The male is the red insect on the top clasping the female by the neck. They can actually fly coupled like this.
