Well, hello there!

Those amazing blue eyes are the easiest way to distinguish the male Scarce chaser (Libellula fulva) from other quite similar blue-bodied dragonflies like the Keeled skimmer (Orthetrum coerulescens) and the male Black-tailed skimmer (Orthetrum cancellatum) (both featured in my blog The skimmers, published in June 2017).

Both sexes of Scarce chaser have brown eyes and a bright orange abdomen when they first emerge, something I didn’t realise when I wrote my first blog about this species, Lifer: Scarce chaser, in June 2025 (though the dragonfly I labelled as female was indeed a female). As the females age, they change to an ochre-brown colour, while the males change to a pruinose pale blue, with a dark tip.

In case you don’t know, pruinescence is a covering of wax particles that develops on the skin as the male dragonfly ages, making it look blue. That pruinescence often gets scraped off during the mating process when the female is holding on to the male’s abdomen. If you look at the image above, you can see these darker scrape marks around the central area of the male’s abdomen, and, looking at the image below of the dragonflies mating, you can see how the female holds on to the male from below, causing the scratching in that area.

These recent photos and sightings were, of course, at RSPB Radipole, in exactly the same location where I saw my first Scarce chasers in 2025. And, just as last year, these dragonflies were very co-operative photographic subjects, though I did eventually just put down my camera and watch as they went about their daily lives. Such stunning creatures!

Golden-ringed dragonfly

Golden-ringed dragonflies are impressive beasties! Though the Emperor dragon (Anax imperator) is larger and has the widest wingspan of all the British dragons (10.5 cms), the Golden-ringed (Cordulegaster boltonii) has the longest body of any British odonata species (females grow to around 8.4 cms). This is a dragon I rarely see as it has a preference for the acidic conditions found in the heathlands and peat bogs of upland locations, so you can perhaps imagine my surprise at finding one on 12 July during my walk around RSPB Radipole, a seaside site with extensive reed beds surrounding a tidal river and lake.

It was patrolling one of the footpaths through the reeds and then, miraculously, settled within viewing distance on a Buddleja with first one, then a second Norfolk hawker. And I was delighted that I was able to share this experience with an interested couple who happened along at just the right time and who were also excited to see both dragonfly species together.

Lifer: Scarce chaser

Here they are, the extremely confiding dragonflies mentioned in yesterday’s blog, the Scarce chasers (Libellula fulva) (also known as the Blue chaser). They were everything you could want in a photographer’s model, perching this way and that to show their best sides; not flying off at the slightest hint of movement behind the camera; the consummate professionals!

So, I managed to get photos of a male, female and the two together in cop. The female (above) is described in my guide book as having an olive-brown thorax and ochre-brown abdomen but, as you can see, she was much more vibrant than those descriptions suggest.

The males have a black thorax and blue abdomen with a dark tip. At a glance, with those colours, they could be mistaken for other dragonflies with similar colouration, until you see their eyes, which are the most amazing shade of blue. (In fact, I’ve just decided to add in a second photo of the male so you can get a better look at those eyes.)

I saw several of these dragons at RSPB Radipole Lakes in Weymouth, which left me wondering why they are called ‘Scarce’ chasers. It seems that, where they are found (in isolated spots in the east and south of England) their populations are relatively small, so they are officially designated as rare. Indeed, in the 2008 British Odonata Red List they were officially listed as ‘near threatened’, so I feel very privileged to have enjoyed such excellent views of these stunning creatures.

Lifer: Norfolk hawker

My wildlife-watching hopes for my short break in Weymouth centred on butterflies and, perhaps, a few birds that I might not see locally, so it was a wonderful surprise to see two new dragonfly species, one extremely confiding (it’ll feature in tomorrow’s blog), one elusive to the point of frustration.

The Norfolk hawker (Aeshna isoceles) was the latter and, on my first visit to the RSPB Radipole reserve, the few times I spotted these dragonflies (easily recognisable by their brown colouring and green eyes), they stayed mostly hidden, perching – when they did actually stop flying – in obscure locations, as you can see from the photos above and below.

Finally, on my last afternoon, when there were fewer people out walking after a morning’s heavy rain and I was battling my way through the extremely overgrown vegetation along the path to the northern bird hide, one of these stunning dragons posed perfectly for me.

Although called Norfolk hawkers, these medium-sized dragonflies have been expanding their range beyond the English county of Norfolk. Their preference for reed beds in swamps and ponds, along streams and ditches, means Radipole provides the perfect location for them to thrive.
