Moon Garden

/ nrowberry / 3 Comments

One of the things on my New Year’s Resolution list, way back before 2020 went crazy, was to create a Moon Garden. I’d got the idea originally from one of Butterfly Conservation’s e-newsletters; amongst the tips for things to do to encourage wildlife was to make a Moon Garden. This is specifically planted to encourage night time wildlife, in particular moths. Most of the plants are white/cream or pale yellow, so they almost glow in the moonlight. Many of them are also more fragrant at night and so should attract plenty of moths. Although at the beginning of 2020 we had already recorded 367 species of moth in the garden, there was always more to hope for!

A patch of garden had been roughly cleared in late autumn, so just needed digging over and any remaining weeds removed.  Here’s the obligatory “before” photo of the soon-to-be Moon Garden area.

Using the list from Butterfly Conservation’s website I ordered some of the plants as ready grown specimens and, to cut down costs a bit, some of the plants as seeds. One of the plants I was particularly keen to grow was the Tobacco Plant (Nicotiana alata) – known to attract the Convolvulus Hawk-moth, a large migrant moth. These grow quite large and tall and have long tubular flowers perfect for the moth’s long proboscis.

Other pale flowers included white alyssums and lavenders, evening primroses, night-scented stocks and phlox, hebe, jasmine and honeysuckle. There were a few, such as white campion, that I simply couldn’t get this year – thanks to covid closures of local garden centres and online sources being swamped with orders. But all in all I was very lucky to get a nice mix of flowers for the moon garden.

A final addition to the garden was Lamb’s Ears (Stachys byzantina)- grown not only for the silvery-ness but also the hairiness of its foliage. This had two-fold appeal – the plant is not only attractive to moths, but the hairs on the leaves are collected by Wool Carder Bees. I’ve only ever seen one Wool Carder Bee in the garden, so had hoped to attract more. Sadly if they did come they did so while my back was turned. But the Lamb’s Ears have grown well, so hopefully next year I can split the plants to get greater coverage.

So this is what I ended up with – or at least this is the stage mid-summer before the Nicotiana and evening primroses took over. For some reason I forgot to take a photo later on before they all died off again! This part of the garden really did smell lovely in the evenings, with the mix of the honeysuckle and other night scented flowers.

So I’d built it, but would they come? Well I may not have got a Convolvulus Hawk-moth yet, but plenty of other species have been more obliging. We started the year on 367 moth species recorded for the garden and to date we now have 405 – an increase of 38.  Of course I can’t prove that all these 38 are a direct result of planting the moon garden, but I’m sure some of them at least must be. And since the garden looks and smells lovely anyway, it’s certainly a win-win thing to do.

Although I was primarily expecting to see the moths in the moon garden at night, it was nice to find the occasional one resting there during the day – like this Garden Carpet on the evening primroses. A slightly more impressive find though was this Poplar Hawk-moth roosting during the day on the Nicotiana.

At night the evening primrose flowers were particularly well used by Silver Y moths.

I run my moth trap most weeks close to where the moon garden now is. It may be co-incidence but some species certainly seemed to increase in numbers this year compared to previous years. The Elephant Hawk-moths for instance were arriving in veritable herds compared to the usual singletons.

The new species were a mix of macro and micro moths. Some I’d been longing to see for ages like this Peach Blossom.

But others were completely new to me. Here are a few favourites – Triple Barred Argent (Argyresthia trifasciata for the purists – a stunning golden striped micro), Lesser Spotted Pinion and Least Black Arches.

The undoubted highlight has to be the moment I discovered a Dark Crimson Underwing in the trap. I nearly put it down as being one of the regular Red Underwings (in my defence, it did after all appear to have red underwings) which I have occasionally found in the garden before. But it looked a bit different, so I double-checked with those much wiser than me and was thrilled to find it was a Dark Crimson instead. Not only did this turn out to be a new species for Worcestershire, it is probably new for the whole of the West Midlands region – result!

So all in all I’ve been very pleased with the results from my moon garden experiment. So much so in fact that I intend to extend it next year and hopefully double the area. Some of the perennials may take years to grow to their full potential, so hopefully it will get better as time goes on. Again it may be coincidence but we noticed more bat activity over the garden this year (hope they didn’t snaffle my longed-for convolvulous hawk-moth, although I suspect it would be too big!), which is great too. Perhaps next year I might plant an area specifically for caterpillar food plants too – it’s all got to be beneficial after all.

Our local branch of Butterfly Conservation had asked earlier this year for moth related articles for the magazine. I was delighted that they included an article on our Malvern Moon Garden. It was Butterfly Conservation’s article that inspired me to plant it in the first place, so it would be lovely if our garden could then inspire someone else to have a go and encourage more moths into their own garden.

I’m not normally one given to poetic quotes, but there’s a line from William Blake – “The Moon, like a flower in heaven’s high bower, with silent delight, sits and smiles on the night” which makes me think of our moon garden – a silent delight giving both me and hopefully the moths great pleasure.

 

 

 

 

Newt News

/ nrowberry / 2 Comments

When we had the new pond put in, way back in February, the frogs moved in almost straight away. There was a lot of croaking and and even some amphibious cuddling, but they completely failed to produce any spawn. I guess the pond was just too new and they didn’t feel it was up to scratch yet. The frogs may have let us down (I did try not to take it personally), but the newts, when they arrived, have more than made up for it.

The first newt plopped into the pond at the beginning of April and was quickly followed by many more. We never really knew how many we’d got, but I reckon at least a dozen must have found there way there in the end. Here’s the first ever one, popping up for air (the pond looks so bare looking back at it now, the plants have filled it out so much more since then).

They are all Smooth or Common Newts as far as we can tell, but they are still absolutely fascinating to watch. For the first few weeks in April, the newts we saw looked fairly laid back, with not much action; just occasionally popping up to the surface for a gulp of air. But as the breeding season progressed, we started to see courtship behaviour and could see the difference between the males and females.

The females are relatively plain coloured varying from beige to olive brown to dark grey. Their bellies in the breeding season go yellower with dark spots – you can just about see this in the female below.

The males tend to be much more jazzy. Certainly the ones in our pond were spotty all over, with a yellowy orange belly and a crest running down their backs and along their tails – visible below. (although the crest of the male smooth newt is quite marked, it is apparently nothing compared to that of the Great Crested Newt – clue’s in the name I suppose!)

Courtship consists of a lot of tail waving from the male – sometimes very energetically, almost aggressively in his determination to impress the ladies. Having got her attention, he deposits a packet of sperm, which she then manoeuvres over to fertilise her eggs. In the video below, you can just make out him producing a tiny white packet of sperm at about the 20 second mark.

 

There can be quite a lot of chasing each other around – sometimes more than just a pair; we’ve seen 4 or 5 chasing each other in a conga line across the pond.

The female lays the eggs individually on the leaves of aquatic plants. Water Forget-me-Nots are apparently a favourite for this, so we made sure there was plenty in the pond. The females grasp a leaf between their 2 back legs, folding them over and depositing an egg inside the fold. She then glues the leaf together and holds it until it sticks.

I particularly like this zen looking female laying eggs.

The females take so much time and care choosing the perfect spot for each individual egg.  The next couple of videos show them carefully selecting and positioning each egg.

 

The eggs were small white blobs in a layer of jelly. Most of the time they were hidden in their protective leaf curls, but occasionally the leaves popped open to reveal one.

We first started seeing baby newts swimming around the pond in mid-May. These first ones were tiny, less than a centimetre long and with no legs.

By early June mini newts with tiny legs had developed. The legs were virtually transparent still, but fully functioning.

They gradually grew, the legs thickening and strengthening, but still retaining their gills.

To get clear shots of the baby newts swimming/walking I very carefully caught a few and filmed them in a tank, before gently releasing them back into the pond.

 

The tank videos are good for seeing the detail, but it is so much nicer to get them swimming free in the pond (although considerably trickier to film). I love this little one determinedly hunting tiny water fleas as he paddles around.

 

I’ve not managed to find any young newts who have fully metamorphosed into efts and lost their gills yet. I’m sure some of them must have done by now, but they have probably left the pond and dispersed into our plentiful weeds. There is plenty of cover around the pond for them to hide in. The closest I’ve got is this one resting on the frogbit (should that be newtbit?), but he still has gills.

 

A lot of the young newts or efts of course won’t make it to adulthood. Lots of things will eat baby newts, not least of which is this Great Diving Beetle which landed unceremoniously in the hedgehog’s water bowl the other night and may have then moved on into the pond.

The efts won’t mature into adults until they are 2 or 3 years old, so it will probably be a couple of years before these youngsters return to the pond to breed. But hopefully some at least will make it and the pond will have done its bit to increase the newt population in our garden. Watching the newts court, lay eggs and develop into efts, has given us such pleasure during the sometimes bleak year that has been 2020; the least we can do is repay them by providing a suitable weed-filled garden for them to live in. They don’t mind that we’re too lazy to weed.

Our Garden Butterflies

/ nrowberry / Leave a comment

The Big Butterfly Count results were announced last week, so it seemed a good time to take a look at the butterflies we’ve had in our own garden this year. Sadly the Big Butterfly Count suggested a poor year for butterflies, although the very warm spring may have meant their numbers peaked before the Count took place – let’s hope that’s the reason.

It might not have been a great year nationally, but we have actually done pretty well here in the garden. By the end of 2019 we had recorded 18 butterfly species in the garden in the 12 years or so we have lived here. In 2020 we were very pleased to add two more to that list.

In the middle of July I was amazed to spot a Silver-washed Fritillary in the garden. It was a bit tatty and probably a bit lost, but you take what you can get with wildlife sightings! Having an overgrown, brambled covered garden had paid off. For once I even had the camera to hand, so snapped a few photos before dashing (artistic license here for the speed) back into the house shouting for Chris to come out and see. It moved from the brambles to a buddleia and we both managed a few more photos before it realised it probably wasn’t in the right place and flew off.

Seeing a Silver-washed Fritillary in our own garden was particularly enjoyable as, thanks to Covid, we hadn’t manage to get out to many of our usual places, so hadn’t seen them anywhere else this year.

Then a couple of weeks later we were sitting by the pond (as so much of 2020 has been spent) when a small butterfly landed on the Eryngium flowers. We thought at first it was a female Common Blue, which in itself would be a bit of a rarity in the garden, but it turned out to be a Brown Argus – our 20th butterfly species for the garden.

Besides the newcomers above, we’ve had a fairly steady stream of butterflies throughout the summer. As with the Big Butterfly Count results, the white butterflies were the most numerous ones – Small Whites in particular seemed to have a good year here in Malvern. I try and record the butterflies I see daily for the Garden Butterfly Survey and for most days through the summer I was seeing at least some Small Whites and some days up to 8 or 9 in one go.  The numbers of Painted Lady butterflies we saw were down on last year, but then last year was a particularly good year for them nationwide.

Commas, Red Admirals, Peacocks and Small Tortoiseshells all appeared, although never in more than 1s or 2s, despite us having a lot of Buddleias in the garden. The grassy areas (we can’t call them lawns any more) produced Ringlets, Gatekeepers and Meadow Browns and the Speckled Woods & Holly Blues liked the brambles and apple tree. I’d planted up a few Bird’s Foot Trefoils in the hope of attracting some Common Blues, so was really chuffed when one finally deigned to appreciate my efforts and land on the flowers.

The final treat for the year was a second brood Small Copper which took advantage of some of the late summer Asters growing wild all over our garden. It’s got blue spots in the wings which apparently makes it the caeruleopunctata form, which was an interesting snippet to learn about.

So it may not have been particularly good news nationally for butterflies, but it seems our Malvern garden has been lucky.  Whether we’ve genuinely had more species visiting or whether we’ve just been seeing more because, thanks to lockdown, we’ve spent more time in the garden I don’t know. Whatever the reason, they have certainly been very welcome little rays of sunshine in an otherwise troubled year.
