Cranefly: Tipula fascipennis

Tags

, , ,

Despite this supposedly being a widespread and locally common species, I had never knowingly seen Tipula fascipennis, the White-barred long-palp cranefly, until very recently. And, though many craneflies are difficult to identify, this one has some very distinctive characteristics. According to Alan Stubbs in British Craneflies, ‘the discal cell is unusually short’, ‘the male genitalia are very prominent’ and ‘the female has a very short ovipositor’. While I might notice the latter, I’m not likely to pick up on the previous two features, but, fortunately, there is one other very obvious characteristic: ‘the wings are unique’ due to the fairly obvious white bar across them. Tipula fascipennis adults can typically be seen between May and August, peaking in late June, in meadows and along the edges of woodlands.

A surprise Spotted flycatcher

Tags

, , , ,

It’s not unusual, during Spring migration, not to see many of the bird species that pass through. Unless they need to rest or refuel, there’s no reason for them to stop, and the urge is strong to reach their breeding locations and get the reproduction process underway. I assumed this was why no Spotted flycatchers had been sighted locally this Spring, though it now seems that a lot of birds are late arriving this year, coming in waves depending on when the weather conditions are favourable for long-distance flights. Then, one evening, I got lucky.

I was sitting at my table/desk, deliberately positioned next to a window with views of the adjacent woodland and out to the Bristol Channel, when I noticed a bird chase a small butterfly along the tree line. My birding skills must be improving because I was immediately on the alert – the bird, the way it moved, its jizz didn’t look like one of the usual birds – definitely not a Robin or a Dunnock, nor, I didn’t think, a Chiffchaff. I kept my eyes on the place where the bird appeared to have landed and reached behind me for the binoculars that live, when I’m home, in a handily positioned bookcase. And there it was, a striking little Spotted flycatcher!

For perhaps 30 minutes I watched it flitting in and out from the trees, attempting to catch small flying insects, sometimes pausing and settling as if preparing to roost for the night but then getting tempted into flight once more by the sight of a succulent titbit. Eventually, it flew further along the woodland and was lost to sight. I can’t imagine a nicer way to spend my evening!

NFY: Marsh fritillary

They emerged a few days later than last year but, as the temperatures rose – if you haven’t caught up with the news, the UK has just experienced a heat wave, with the hottest May temperatures ever recorded, the Marsh fritillaries began to fly at the local nature reserve where a colony was illegally established three years ago.

These butterflies shouldn’t exist where they do but they certainly are a stunning sight to behold.

Fly: Sicus ferrugineus

Tags

, , , , ,

With a long cylindrical body that curls under its own abdomen, this fly looks rather odd, as do all 25 British species belonging to the Conopidae family of thick-headed flies, the family of beegrabbers and waspgrabbers. The rust colour of this particular species has led to its common name Ferruginous beegrabber (Sicus ferrugineus), and it really does grab bees.

Female beegrabbers linger on and around flowers, waiting for their prey – in this particular case, various species of bumblebee – not to eat the bumblebees but to grab hold of them and, using their ovipositor, inject an egg into the bumblebee’s abdomen. After hatching, the beegrabber’s larva develops inside the abdomen of the bumblebee while it’s still alive, though the bumblebee does eventually die and the larva pupates inside the corpse.

Sicus ferrugineus is common throughout most of Britain and Ireland, and the adults can be seen from May to September. Look for specimens sitting patiently on flower heads waiting for some unsuspecting bumblebee to fly in.

A Tawny fledgling

I was soaked from un-forecast rain showers when I reached the bus stop outside Cosmeston Lakes Country Park and just hoping a bus would come quickly so I could get home and into dry clothes. But, when I got there, two of my birding acquaintances were also awaiting a bus and told me, excitedly, that they had just been watching a fledgling Tawny owl sitting low down in a tree close to the car park.Although I’ve seen the occasional adult Tawny and sometimes hear them calling at night in the woodland adjacent to my building, I hadn’t seen one for a couple of years and had never seen a fledgling. So, understandably, it only took me a moment to decide that I simply had to go for a look, soaked or not.As it was still raining, I didn’t want to damage my camera so only managed to get a few quick photos, and I also didn’t want to disturb the bird, though I’m sure one, or both of its parents were perched nearby, well hidden amongst the foliage, keeping a close eye on their offspring. What a special sight this was – a bundle of fluff, perched on a branch, looking sleepy and making the occasional low chirruping sounds.

p.s. I wrote this post last week. In the interim, this little fledgling has become something of a local celebrity, and it’s been really heartwarming to see how delighted people have been at seeing it. It’s also been good to see how respectful and protective of the bird the visitors have been. Of course, I have since revisited the site as well, and managed to shoot this short video clip of the fledgling. Enjoy!

Burnet rose

The Burnet rose (Rosa spinosissima, formerly Rosa pimpinellifolia) used to grow in my local area but hasn’t been recorded here since 2017 (I don’t know why – perhaps changing use of the environment where it used to grow), so it was good to see a lot of it in flower on the Isle of Portland.

This shrub usually grows low to the ground, forming clumps, sometimes with creeping suckering branches that form new plants. It’s most confined to dry sandy seaside areas and, if growing inland, favours calcareous locations.

My Flora Britannica says its pretty flowers have ‘the sweetest smell of any native rose – a mixture of honey and jasmine’; sadly I didn’t get down low enough to give them a sniff! It’s on the list for my next visit.

Five little cygnets

I’ve never really understood how anyone, let alone a talented writer like Hans Christian Andersen, could label a cygnet an ‘ugly duckling’. In my opinion, there is nothing even remotely ugly about a cygnet; it is the very embodiment of cute.

These five very young cygnets were with their Mute swan parents, pottering along the water’s edge where the River Ely flows in to the western edge of Cardiff Bay, and watching them certainly brightened up a very dull, grey, occasionally wet day. I hope you enjoy this massive dose of cuteness as much as I did.

Hoverfly: Dasysyrphus albostriatus

, , , , ,

It seems hard to believe that this crazy looking fly larva …

… could become this rather striking hoverfly, Dasysyrphus albostriatus, also known as the Stripe-backed fleckwing.

I’ve seen similar larvae before, either those of this exact species or another of the Dasysyrphus species (see The Godzilla of hoverfly larvae, October 2021), but I’ve only once seen an adult and that view was not a good one, so I was very pleased to get a closer view of this individual during a recent local walk.

My British Hoverflies guide book says ‘the downward-facing oblique bars on abdomen segments T2-T4 and the pair of grey stripes on the thorax make this species straightforward to identify.’ This hoverfly prefers to inhabit woodlands and can be seen from Spring through to early Autumn, though is most often seen on sunny days in April and May.

Weymouth trip birding roundup

Tags

, , , , , , , , , ,

The main reason for my trip to Weymouth and Portland from 7 to 14 May was to celebrate a BIG birthday and, for me, there’s no better way to celebrate than to spend time in Nature, watching the birds, butterflies and other creatures that make my heart sing. The fact that I was able to add eight new bird species to my 2026 list was a welcome bonus but certainly not a necessity – I get just as much pleasure from seeing the ‘ordinary’ birds (the Skylarks and Stonechats and the Pipits feeding their families) as I do from seeing those I don’t get to spot on my home turf. And, in fact, I didn’t even see one of the biggest birding highlights of this trip, a Bittern that was booming from deep in the reed beds during two of my visits to RSPB Lodmoor. I didn’t manage to get many great photos of the birds I saw but here are a few …

One of the artificial islands used for nesting by Black-headed gulls and Common terns (and, it seems, the occasional Canada goose). The air around these little islands is always alive with birds coming and going, and the noise is often raucous.

Though Reed and Sedge warblers and Reed buntings sang constantly from the reed beds, they were rarely visible. I got a lucky fleeting glimpse of this Sedge warbler.

Each time I went to Lodmoor, I was treated to Swallows like this one, as well as House and Sand martins zipping about overhead, and also coming down to gather mud and bits of vegetation to help build their nests.

On several days, at both Lodmoor and Radipole, I watched Marsh harriers flying back and forth, sometimes soaring, often just skimming the tops of the reeds as they hunted for food.

From the coastal path above Portland’s west cliffs, I spotted Guillemots and Razorbills, several gull species and Gannets, as well as these Kittiwakes, an adult on the right and a juvenile below left.

If you’re interested, the birds that were new sightings for me were Common tern, Bar-tailed godwit, Sanderling, Little tern, Whimbrel, Kittiwake, Great white egret, and that booming Bittern.

Mr and Ms Beautiful demoiselle

I didn’t spend a lot of time looking for odonata species during my recent visit to Weymouth, partly due to the weather conditions – when it was sunny, there was almost always a strong cold wind blowing through the areas where I usually find dragonflies, but also because the RSPB has made the decision, despite the protests of very many people, not to spend money on maintaining many of the footpaths at both the Lodmoor and Radipole nature reserves, meaning some areas are already becoming inaccessible. (I won’t go in to my opinion about the RSPB here – suffice to say it couldn’t get much lower, and the organisation will never again receive any financial support from me.)

On the one afternoon the weather was favourable, I was exceedingly lucky to find several species that were my first sightings for 2026. The Blue-tailed and Red-eyed damselflies will be covered in future blogs, when/if I get more and better photos of them at home in south Wales, but I couldn’t resist sharing these images I did manage to get of the aptly named male (above) and female (below) Beautiful demoiselles (Calopteryx virgo) that were wonderfully entertaining as they flitted amongst the tall reeds along the edge of a path at Radipole. Such gorgeous creatures!
