Druridge Bay before the rains

Visiting our daughter in the North East will usually find us dragging her somewhere coastal. This time it was Druridge Bay in my home county of Northumberland. One of the most glorious places and one that has special childhood memories for not least family caravan holidays in Amble at the north end and Cresswell and Cambois at the south.

Also, first demo/festival/benefit I attended (aged 10) was to protest against plans to build a nuclear power station there. We blocked that, but I see now that they’re hoping to exploit this beautiful and wild place by opening an open-cast coalmine. FFS.

Meanwhile, the birds are blissful in their ignorance of the mankind’s machinations: Bar tailed Godwit, Barnacle Goose, Blackbird, Black-headed Gull, Blue Tit, Chaffinch, Coal Tit, Common Scoter, Cormorant, Curlew, Eider, Goldfinch, Great-crested Grebe, Herring Gull, Jackdaw, Lesser Black-backed Gull, Magpie, Marsh Tit, Oystercatcher, Pheasant, Pink-footed Goose, Red-throated Diver, Redshank, Reed Bunting, Rook, Sanderling, Shelduck, Sparrowhawk, Starling, Stonechat, Turnstone, Wren…it’s possible I’ve overlooked a couple of others.

Fighting hard against low light levels the whole time, we departed just as the rain started and trip to St Mary’s Island and Lighthouse was scuppered by weather and high tide.

Every drop counts at Grafham Water

Had a short visit, via a circuitous A14 diversion to Grafham Water reservoir while the sun was shining, drove home in the rain. Intriguingly, there was a warning sign about not swimming and needed higher-spec buoyancy aids because the water is aerated and so, presumably, of lower, less buoyant density than normal water. Anyway, a few photos. Not of the sign.

Box-tree Moth, Cydalima perspectalis

The Box-tree Moth, Cydalima perspectalis, is an Asian species of moth (usually seen in Japan, China, Taiwan, Korea, and India), that is gradually spreading, presumably with the advent of box hedges on new housing estates, across the South East of England, and in East Anglia.

It would most likely have arrived as eggs/larvae on imported box plants(Buxus), and it was first recorded in the UK in 2007. Its larvae can rapidly eat their way through a box hedge. Another reason to go native when it comes to planting…although it is probably too late for native box now though.

I recorded my first Box-tree moth in July of 2019 and have seen dozens since. It is a quite beautiful, exotic-seeming moth. There is a dark melanistic, form, which is a common genetic aberration in lots of animals; see also the Industrial Evolution of the Peppered Moth.

Wiki has more details on its recordings: first seen in Germany 2006, then Switzerland and The Netherlands in 2007, France and Austria in 2009, Hungary 2011, Romania, Spain, and Turkey. Also now in Slovakia, Belgium, and Croatia, and by 2016 Bosnia and Hercegovina. During the preparation to the 2014 Olympics in 2012 it was introduced from Italy to Sochi with the planting stock of Buxus sempervirens. A year later it was seen to be defoliating Buxus colchica. Now present in Toronto, Canada as of 2019.

Recently, I’ve seen a lot of pheromone traps hanging in trees close to a garden box hedge and even at a National Trust property. These traps are commonly used by moth-ers who place a pheromone lure in the trap, and draw in a target species for recording, examination, and photographing. All in the name of citizen science.

Unfortunately, this is not the way to deal with what box gardeners perceive as a pest. Indeed, hanging a lure in your garden will have the exact opposite effect of what you hoped. The females if they are in your area will be drawn to the box plants because that’s the food plant for their larvae. In the meantime, they will be pumping out sex pheromone into the air and drawing in the males who will mate as soon as they encounter the female. If you put out a pheromone lure, you are likely to be amplifying the sex signal and will draw in more males. You will trap some males but it really only takes one pairing on your box hedge for it to be devastated by box-tree moth larvae.

So, how do you deal with an infestation of Box-tree Moth larvae on your bushes? Well, you could go the nasty route and spray pesticide, but that will harm other beneficial invertebrate species. You could make a solution of washing-up liquid, but that’s unlikely to work well. You could pick off the caterpillar and…dispose of them. But, in this area, at least, I’d say your Box are doomed, perhaps better to find another native plant species to replace it for hedging.

If you see this species, there is a major project to record their spread and changing colour forms through the UK. You can record details here.

Today’s wonderful marvel of the day

UPDATE: One Merv in the night and another to join it by morning!

I only started mothing with a scientific trap a little over a year ago (24 Jul 2018, to be precise) but have logged and photographed well over 300 different species since then.

I heard about Griposia aprilina, aka the Merveille du Jour, a few weeks after I started and thought it would be a nice specimen to see. But, its larvae feed on oaks and as far as I know, there are none particularly close to our garden. I was ever hopeful of seeing this little marvel but I didn’t hold out much hope of it ever making an appearance.

This beautifully marked green (and black and white) moth usually emerges in adult form in early October to fly and mate. This time last year, I hadn’t seen one and even though I lit up all the way through the autumnal and winter moth season up to mid-December or thereabouts, Merv never showed.

After our recent wildlife, yoga, and sightseeing trip to the Greek Island of Kythira, I got back to lighting up only a couple of nights ago. Tonight, I was about to head for bed, but thought I would check the trap for Thorns and Sallows only to be rewarded with the little wonder that is the Merveille du Jour. It’s odd that some British moth-ers tend to call it a “Wonder of the Day” when they translate its obviously French name, using the Germanic “wonder”. Either way, it’s a marvellous and wonderful moth.

White Stork, Ciconia ciconia

The White Stork, Ciconia ciconia, is a scientific tautonym, its binomial being duplicated to indicate that ciconia is the “type”, the archetype, of the family Ciconia. This is the bird of birth myth, the one that bears the infant baby to the homes of expectant parents. Perhaps the myth arose because they build great nests of straw on chimneys in the summer.

Anyway, the White Stork is rarely seen in The British Isles. You might see them nesting on rooftops in Germany, Poland, Finland, and beyond. They are relatively common across Europe and not of conservation concern, wintering in southern Africa and breeding far and wide into Europe and Asia. They need thermals to soar and so cross from Africa via the Straits of Gibraltar and “The Levant” rather than attempting to navigate the Mediterranean Sea, which obviously doesn’t produce the thermals they need.

There was much excitement among Cambridgeshire birders when a ringed bird was spotted at a couple of RSPB sites, Ouse Fen and Fen Drayton, in April 2018 and another (the same one?) sighted in various places across the county in early 2019.

There is a small flock of captive, ringed White Storks at Johnson’s Farm in Old Hurst, the farm with the crocodiles. My photos on this blog post were all snapped at the farm on Talk Like a Pirate Day 2019. Aharrgh.

Croc of the Rock

It’s Talk Like a Pirate Day, which holds a special place in the hearts of Mrs Sciencebase and myself that has nothing to do with Dubloons, wooden legs, nor eyepatches. Nevertheless, a day out at a local farm seemed a sensible way to celebrate, hahah. So, we headed into deepest, darkest Huntingdonshire, we met no one on the way to St Ives (not that one), flew around RAF Wyton, headed for Pidley (birthplace of our long-gone feline) and took a sharp left after a U-turn to Johnson’s Farm in Old Hurst.

Now, Johnson’s farm has sheep and cows, a butchery, and a farm shop and cafe. But, it also has Macaws and Emus, Meerkat(s), Capybara, giant rabbits, and (not seen) Wallabies. It also has a flock of about 7 or 8 Storks, a bird species that like the Gene Genie loves chimney stacks, but usually those of continental central and eastern Europe rather than the British Isles. Johnson’s also has some tropical birds, a boa constrictor, oh and there is something else…crocodiles.

The crocodiles are I believe part of a conservation, breeding programme, but from the aforementioned working farm and butchery point of view, they are the most efficient means of disposing of the tons of butchery waste generated each year. which has crocodiles…I don’t know if any of them have a ticking alarm clock in their stomach.

They’re not quite as cute as the Horsey seals, maybe not quite as watchable as the birds I photograph, and definitely not as up-close-and-serious as the moths. But, they are, you must admit, rather photogenic in an almost tropical prehistoric way…needles to say, I got a few snaps.

Moth of the Moment – Hummingbird Hawk-moth

I’ve seen Hummingbird Hawk-moths, Macroglossum stellatarum, on a few occasions but previously when travelling abroad (specifically, Croatia (2017), Germany (2018), and Italy (2010), and if memory serves many years ago France, 1996). I’ve only ever got awkward, blurry, and low-resolution photos. Earlier in the summer, a friend gave me some red valerian plants, which are a favourite of this species; same friend who donated the snails for our newly resurrected pond, #pondlife.

That was back in early June. I had high hopes of seeing swarms of this bird-like Lep, which is an immigrant to the UK but occasionally seen in numbers when there’s an irruption. But, it seemed like it wasn’t to be, until this balmy September day (just 17 Celsius in the shade though). Finally, a HBHM has turned up. Initially, I wasn’t quick enough with my camera, but at least I saw it before it headed off over our roof. But, then twenty minutes later it was back, or perhaps it’s a second one. I was ready. Shutterspeed 1/4000th of a second, still not fast enough to freeze the moth’s wings in flight, but at least you get the gist.

Moth of the Moment – The Bristly Nun

The moth mothers often abbreviate as the SHC, the Setaceous Hebrew Character, Xestia c-nigrum, turns up a lot in scientific traps from late summer into the autumn. The name refers to a marking on its forewings that resembles the Hebrew letter, nun, and the setaceous means “bristly” and refers to the hairs around the character. Hence my tongue-in-cheek reference to it being the Bristly Nun. The setaceous separates it from a distant relative but fellow noctuid, the spring-flying Hebrew Character, Orthosia gothica, it has the nun, but is clean-shaven and so lacks those bristles.

Setaceous Hebrew Character, Xestia c-nigrum

The SHC also flies in its first brood from May to June, but the second brood seems to be far more numerous August to September. You can see from my records for 2019 here that I’ve seen hundreds, with a peak in August of well over 100 on a single night. Nothing compared to the numbers of fellow noctuid the bombastic Large Yellow Underwing, Noctua pronuba. Apart from subtle variation in marking definition and some size difference, the SHCs mostly look alike. Again, in contrast to N. pronuba, which can vary considerably in their choice of browns and greys.

Anyway, there were no NFY (new for year) moths in the trap this morning, so I focused on the SHC on a whim and placed a small tribe of those from the haul on to my trusty chunk of mossy and lichen-covered bark for a quick photoshoot and a macro closeup or two.

Moth of the Moment – Large Thorn, Ennomos autumnaria

Large Thorn, Ennomos autumnaria, attracted to the UV lamp of the scientific trap, night of 16th September, didn’t get a chance to enter the trap before I potted it to photograph this NFM*.

Large Thorn

The species, like the other geometers we know as Thorns looks like an autumnal leaf, and occasionally quivers when roosting as if to follow the breeze. It’s a relatively large moth, but the “Thorn” of its vernacular name refers to a spike on the larva and is nothing to do with the adult being at all prickly.

A rather worn Orange Sallow

Also around the trap at the same time a worn Orange Sallow (worn, but NFM*) and a Centre-barred Sallow, both very autumnal in appearance.

*NFM = New for me
