Ruddy Darter dragonflies tend to perch on the tips of sticks and vegetation overhanging the water's edge, flying away and returning repeatedly.

Darter Dragonflies do like to perch on items low over the water. Here a Ruddy Darter Dragonfly hunts and patrols from a turned-over Iris leaf.

The seed heads mean no more to this male Ruddy Darter dragonfly than a convenient place to perch to warm in the sunshine.

A Few Ruddy Darters are stationed around the ponds. This one was perched on a dead Blackberry stem ready to leap out to catch any passing midge.

A mature female Ruddy Darter Dragonfly on the tip of a cut Blackberry stem shows the sun shining through the orange pterostigma - the coloured patches near the tips of the wings - that are present but takes many forms in the various Odonata species.

This female Southern Hawker Dragonfly individual has frequented a sunny and sheltered section of the meadow for several October days. We know her from her torn wing and tatty wing tips, but she can fly well.

Dragonflies end their 2 or 3 year life as predatory aquatic larvae by crawling up a plant stem and emerging from a pupal case (Exuvia) to expand into the flying insect. This image shows the intricacy of the case including transparent eyes and the strands which are insides of the breathing spiracles. The insect exited out of the upper back. Thanks for Rory for the gift of the Exuvia from his garden pond.
If you are interested in more detail we photographed an exit sequence of a different dragonfly species in 1999 (with far inferior equipment) which you can see at Dragonfly Emergence sequence

Dragonflies really are incredible creatures. Unlike the one shown a few days ago this is definitely a female. Sexing can be difficult - the colours change with maturity and even with temperature and other characteristics don't appear in photos

Finally the hot weather has brought out the first dragons - well Hawker Dragonflies at least!
This female Southern Hawker Dragonfly is perched on a twig basking in the hot sunshine.

Here is a head shot with an inset showing the compound eye.
Compound eyes are an array of uni-directional cells rather than lens and retina. Resolution is poor but they have huge angle of view, are lightweight, detect movement quickly, and some detect polarisation (used to navigate by skylight).
More info at Wiki Compound Eye
.
The streaks on the eye in the main image are Moire (artificial digital patterning) effects at the reduced resolution used in these archives.

Female Southern hawker dragonflies don't systematically patrol ponds like the males do, but hunt around the hedges and rank grass. Here she is hung up on a dead stem.

Our first (and so far only) sighting this year of a Southern Hawker Dragonfly. This is a female hanging on stinging nettle flowers.

4 images of a female Southern Hawker Dragonfly in this pic, if you can only find them spread across the confusing ground flying right to left.

This is a detail of the last image in the montage (far left).
The male of the Southern Hawker Dragonfly is our most commonly seen large Hawker, but we don't often see the females like this one except when depositing eggs at the edge of a pond, so a pleasing moment.

This female Southern Hawker dragonfly was flying into a strong wind allowing an unusual 3 images in succession to be in reasonable focus. You can see from the difficulty of seeing the wings against complex background the reason we use a simple 'blue sky' background in the indoor 'flight tunnel'
