Celtic Damsels

This will be the last post from my trip to Scotland in 2014 during which we made an early morning visit to the osprey nest at RSPB Loch Garten to hopefully catch a glimpse of one of these magnificent predators. There was an adult on the nest but without more magnification than I had I couldn’t get up close (but it looked spectacular through binoculars!):

The ospreys overwinter in sub Saharan West Africa and are another great conservation success story. Despite that they’re conservation status is still amber with only 200 pairs in the UK. They can cover up to 275 miles a day on migration and they stop off on the way south for a couple of weeks to feed up, they also stop on the way north, but only for a few days,to ensure they arrive at the breeding grounds as early as possible to maximise the length of available time for the actual breeding.

Whilst at RSPB Loch Garten we got an excellent steer from one of the RSPB girls on a couple of pools in the forest where we could find dragonflies. It had been a grey morning, but as we arrived at one of the pools the sun emerged, and with it, the dragons. I’ve already posted dragon pictures from these sites in an earlier post, and here are some more images of mating damsels:

The northern damsels are in tandem, the blue male is clasping the female prior to escorting her around the pool to find suitable egg laying sites. Large red damsels were also mating over the pool at the same time:

I think this picture of the large red damsels is the best insect photo I’ve ever taken. I like it because they’re in motion and in the process of doing something, and the shadows are cool! The large red can only really be confused with the small red, but the small red has red legs and doesn’t have the yellow bands which can be seen on the female in this picture.

I also like this floating spider:

I don’t know what species the spider is, I’ve never seen one like it anywhwere else. The markings are distinctive and it may be the same species as the one in the previous post, but I was assured by the experts at the British Arachnological Society that it could only be unambiguously identified by microscopic examination after dissection.

The majestic Scots pine trees of the Abernethy Forest

The two dragonfly pools were in the Abernethy Forest. I think it’s difficult to convey the atmosphere of a forest in photographs because the temperature and humidity, the sounds and the smells, all contribute to the feeling of a forest, and none of these can be captured in a photograph. Even the light is difficult to capture because the camera settings required to give a good quality image don’t necessarily recapitulate what it actually looked and felt like.  So the picture above of the Scots pines of the Abernethy Forest is the best I could do, but having said all that stuff, in the absence of all the other sensory inputs it does convey a little bit of my memories of the forest. I hope you know what I mean and I hope you like it!

As I mentioned at the top of this post, this is the last installment of my ‘Cairngorm Chronicles‘. It was a fabulous trip and we saw some breathtakingly beautiful places and lots of wildlife. I can’t wait to go back and see more creatures peculiar to that part of the world such as grouse, ptarmigan, capercaillie and red deer, as well as the ones I missed on this trip such as crested tit and crossbill. So much to see and so little time…

Dragonfly drama

Early last Saturday morning I set off for Paxton Pits, a group of lakes on the edge of St Neots, between Bedford and Cambridge. It was anticapted that we wouldn’t see much birdlife but there could be some inteersting dragonfly activity. And apart from a lone turtle dove (which justifies the trip on its own!) and a sparrowhawk, we noticed surprisingly few birds. But the Odanata were there in abundance with large numbers of various species of damsels and true dragons.


Common blue damselfly

I spotted this common blue (Enallagma cyathigerum) before I’d even got out the car. This one a male, was perched on a seed head at the edge of the carpark and there were several others in the vicinity warming themselves up in the early morning sunshine. At the other side of the carpark is the visitor centre which has a small pond outside and over the pond were a red eyed damsel (Erythromma najas) and another common blue warming up on the same rush leaf:

Paxton Pits are disused gravel workings and have been turned into a nature reserve that is managed by Huntingdonshire District Council with the back up of the voluteers of the ‘Friends of Paxton Pits’. If you happen to be contemplating a visit to the Pits, there is a lot of information on their website: (https://sites.google.com/site/paxtonpitsnaturereserve/home), and the reserve also has a blog where sightings at the lakes can be recorded: (http://paxtonpits.blogspot.co.uk/). The website lists all the Odanata that have been resident there and many of them were on display on Saturday. They don’t all emerge at the same time of year so it would never be possible to see all of them during one visit.


Another common blue damsel on final approach to land on a stinging nettle stem

The Pits are adjacent to the River Great Ouse and swarms (literally!) of banded demoiselles (Calopteryx splendens) were fluttering within 20m or so of the banks of the river. The banded demoiselle is one of two species of demoiselle in the UK and the only one in the east of England, and I think they’re absolutely beautiful as they sparkle in direct sunlight:

The other species of UK demoiselle is called the ‘beautiful demoiselle’ (Calopteryx virgo) and is found in the south and west but not the east. It is most easily distinguished from the banded version because the wing pigmentation in the male extends to the base of the wing, so it’s a much bigger spot than those on the wings of these banded demoiselles:

Above and below: male banded demoiselles

And the female beautiful demoiselle  has broader wings with a brown tint that’s lacking in the banded demoiselle. The male demoiselles were busy chasing females with all thoughts turned to mating.

But in the midst of all the the mating activity, danger, as always, was lurking in the undergrowth. This unfortunate female common blue damsel had been caught in  a spider web and was in the midst of a mortal struggle with the owner, which she eventually lost:

The male common blue was also caught in the web and was struggling to extricate himself. Fortunately for him, all the spiders efforts were needed to subdue the female and whilst it was otherwise distracted he made his escape whilst the female eventually succumbed to the spider venom.

It’s also that time of year when dragonfly larvae are metamorphosing into adults. The larval stage of all dragonflies is aquatic and so they require gills or ‘caudal lamellae‘ to breath underwater, and these can be seen protruding from the end of the abdomen of the larva above. At the end of its aquatic life the larva climbs a stem out of the water and emerges from its larval skin as an adult, leaving behind its discarded outer casing, or ‘exuvia‘:

As well as the damsels, several species of true dragons were on the wing including brown hawker, migrant hawker, black tailed skimmer, and the grandaddy of all UK dragons, the emperor (Anax imperator):

The emperor, as its name suggests, is a whopper. It is also an aggressive defender of its territory, a consummate aeronaut and a ferocious hunter, taking prey as big as other dragonflies. It’s easily distinguished from other dragons by its sheer bulk, the apple green thorax and the drooping abdomen. I sat and watched this one for some time and he rewarded my patience by posing for a portrait on a stem just  a few metres away:

And after all the dragon activity I peered into the water on the way home and spotted this little chap:

A young newt

I don’t know what species of newt this is but it’s still so young it hasn’t adapted to air breathing and still has its feathery gills which are visible just in front of the fore legs.

It’s been a long time since I last posted so it’s good to be back Life should be generally less busy for the back end of the year and I’ve got lots to share, so hopefully I can start to post more regularly again!
