This Broad bodied Chaser is one of the unmistakable dragonflies. Only the male of this species has the blue pruinescence - a powdery blue coating that gets patchy over the weeks that the insect lives.

We include this static shot taken later to show the wonderful powder blue abdomen (and it really is powdery and gets worn off with 'living'). The blue is a strictly male feature - the female is orange and not a powder.

A first for us here is seeing both male and female Broad Bodies Chaser Dragonflies at the same time on one pond. This is the female some 5 metres from the male.

Our first Dragonfly (as opposed to Damselfly) sighting this year is a Broad-Bodied Chaser female (actually seen briefly on 9 May 2011). We think this is the first sighting in Buckinghamshire this year

Here we have a female Broad-bodied Chaser Dragonfly. The male of the same species has the back of the body covered in a powdery blue pruinescence.

A few minutes earlier 'grabbing' an image before going back to the house for the 'macro' kit, we caught this view of the abdomen's translucence.

This beautiful Broad-Bodied Chaser Dragonfly was using the withering flag iris as a vantage point - it has no interest in pollen or nectar. Shortly afterward an orange female flew by and he flew off after her.
The blue back (on the males only) is powdery and bright in Ultraviolet. If you are interested see Dragonflies in Ultraviolet from part way down & the top item on the page that follows. They are NOT dead - just cold, and like all the others flew off fine after warming in the sunshine.

A first for us here is seeing both male and female Broad Bodies Chaser Dragonflies at the same time on one pond. This is the male which you can see he has already damaged a wing. Our experience is that this sort of damage is most usually from being caught by brambles or wild rose thorns. Dragonflies seem to be able to fly fine with half their wing surface missing from encounters with thorns and bird beaks.
He is perched on a Yellow Flag Iris flower but he is not interested in nectar - he is a hunter using the flower only as the highest nearby perch.
The blue back is a powder that gradually gets rubbed off. It is very bright in UV light - see our UV section on the web site if interested.

This is the first dragonfly we have seen here, with beautiful powder blue (and powdery texture) abdomen. It has a wingspan of about 7cm.

A few days later we caught this female Brown Hawker Dragonfly, but events transpired that prevented us photographing her in flight. She needed a chance to warm herself up for flight, so we hung her in the hedge. The blurred tips of the wings is her vibrating them to raise the temperature of her flight muscles

After the indoor shoot we took her out for release and took some more studies in sunlight until she flew off. This detail is looking from the top of the head (eyes at the bottom) down the face at the top.
We estimated the number of eye segments at 30,000, couldn't believe it, but then found a reference to an exact count for the 'American Common Green Darner' at 28,672 in an excellent UK book by Steve Brooks ISBN 0-953-13990-5 page 8.
The cells do not form images (unlike the ridiculous Hollywood and nature documentary illustrations) so that IS the resolution - about 10% of a 'VGA' (640x480) colour monitor but of course wonderfully sensitive to movement, colour vision including UV, and very robust. According to the book, 3 additional eyes in a triangle at the top are very sensitive to light and are directly used for orientation in flight.

This Brown Hawker Dragonfly female was having great time feeding on midges - you can see one here hanging out of the bottom of her mouth.

This is a Brown Hawker dragonfly female flapping her wings as she clambered up a hawthorn twig during a photo-shoot to photograph her in flight (but the flight images didn't capture the 3-D feel).

A bit of sunshine on not too-cold days bring the dragonflies out - mostly on feeding hunts over the long grass.

The Brown Hawker Dragonflies come out and hunt over the meadow as soon as the afternoon sun shows his face.

Flying across the wind keeping approximately the same distance from us before turning towards us. Here is part 1 of the sequence.
