Devil’s-bit scabious (Succisa pratensis) has a beautiful flower that paints the wildflower meadows at Lavernock Nature Reserve in shades of purple lusciousness and provides some very welcome late summer nectar and pollen to a host of insects, particularly bees, flies and butterflies.

And that name? Well, the story goes that the devil was not pleased that the plant’s medicinal properties were healing the skin conditions of people suffering from bubonic plague and scabies so, in a fit of rage, he tried to kill off the plant by biting off the ends of the plant’s roots. Ever the party pooper!

1000 blog posts, blogging, blogging about nature, personal milestone, Robins, writing a daily nature blog

Today marks a personal milestone, as this is my 1000th consecutive post since I started this blog way back on 7 December 2015. My original intention was to make the daily blog a personal challenge for 2016: I’d done ‘photo a day’ challenges previously so the blog was just an extension of that idea. And at the end of 2016, I stayed keen and carried on.

180830 robin (1).jpg

There’s an element of pressure in posting each and every day, constantly trying to find new and interesting topics, always keeping an eye out for good photo opportunities and, when a holiday is in the offing, writing blogs for a week or two in advance, so as to keep the daily posts going. If only I was getting paid for doing it!

180830 robin (2)

Along the way, I’ve amassed a loyal band of followers and enjoyed some lovely interaction with others who love the natural world as much as I do. My sincere thanks to each and every one of you who have hit the ‘like’ button or taken the time to post a comment. Your feedback and support are very welcome.

180830 robin (3)

In future, I may not post every single day but, for as long as I can find something wonderful / marvellous / colourful / stimulating / fascinating / entertaining / smile-inducing to share, this blog definitely will not stop. And as one of my followers, Theresa Green, wrote on her blog everyday nature trails, ‘there’s never nothing to see’.

p.s. Some of your favourite posts have been about Robins so these photos seemed appropriate. 🙂

Wild word: cocoon

Cocoon: Noun; A silky case spun by the larvae of many insects for protection as pupae (Oxford Dictionary).
The cocoons in my photos are those of Burnet moths, both 5-spot (below left) and 6-spot (below right): you can’t tell the difference in the cocoons from the outside – I just know which moths were present in the locations where I took my photos.

180828 5-spot burnet moth
180828 6-spot burnet moth

After hatching from their eggs, the caterpillars/larvae of both moths feed on plants from the pea family; the 6-spot burnet is particularly partial to Common bird’s-foot trefoil, which is why I see a lot of these moths at Cosmeston.

180828 occupied 5-spot pupa
180828 occupied 6-spot pupa

When they’re ready to pupate, the caterpillars find themselves a suitable location, often high up on a sturdy grass stem (though I have seen them on other plants), and spin an oval-shaped cocoon. The cocoons pictured above are still occupied by caterpillars in the throes of metamorphosing into moths, a process which takes about two weeks.

180828 empty cocoon (2)
180828 empty cocoon (1)

These are the empty cocoons that remain once the adult moths have emerged (with the remains of the larvae’s pupae cases poking out the tops). The cocoons are quite sturdy: their yellowish-white papery structures often seem to last for a month or more after the adults have departed or even until the grasses themselves collapse with the coming of the wild winds and chilly days of autumn.

Butterflies 2018

British butterflies, butterflies, butterflies in Britain, UK butterflies

The sharp-eyed amongst you may have noticed that I recently added a new page to this blog (see the link in the top menu). As it says on the page, Butterflies 2018 is a chronological list of the first time I’ve spotted each British butterfly species during 2018. This isn’t like my Birding 2018 challenge, where I’m deliberately trying to see 200 species in a single year – 2018 just happens to have been a very good year for me for seeing more butterfly species than ever before (bear in mind that I’ve only been living in Britain three years, so I haven’t had a lifetime of butterfly watching, and there are plenty more species I’ve not yet seen). And I figured it would be a good idea to have a chronological list as a personal aide-memoire, so I know which butterflies to look out for in which months in future years.

180828 Common blue

Common it may be, but I still think the Common blue is one of Britain’s loveliest butterflies.

Seeing spots before my eyes

autumn migration, bird migration, birding, birdwatching, British birds, Cosmeston, Cosmeston Lakes Country Park, Muscicapa striata, Spotted flycatcher

The autumn bird migration is now in full swing in south Wales and almost every day migrating birds are being spotted at Cosmeston Lakes Country Park, where they’re stopping off to refuel before they tackle their long flights to warmer over-wintering locations in Europe and Africa. One that I find particularly charming is the Spotted flycatcher (Muscicapa striata), which is not really spotted at all, more streaky and stripy. The scientific name is more accurate: Muscicapa is a combination of the Latin word musca, meaning fly, and capere, meaning to catch, and the epithet striata is from the Latin striatus, meaning striated.

180827 spotted flycatcher (1)

I saw my first Spotted flycatcher at Cossie on 7 August.

A week later, on the 15th, I had two sightings.

The 20th was a bumper day, with three birds, two obviously travelling together, and another doing its own thing.

And last Friday, the 24th, a birding friend put me on to a single bird, that was catching flies in the paddock I walked through on my way home. Fingers crossed I manage to see a few more before they all disappear for the winter.

The Chinooks of the hoverfly world

These are a couple of the Volucella species, the Chinooks of the hoverfly world and, if you live in the southern parts of Britain, they’ll be out there hovering along woodland paths and in local parks near you right now. Before you panic and get out your fly swat, these hoverflies may look a little menacing – and some of them even look a bit like Hornets – but, please rest assured, they are all completely harmless. And, if you take a little time for a closer look, you will soon see what incredibly handsome mini-beasties they are.

180826 Volucella zonaria (4) 

180826 Volucella zonaria (3)
180826 Volucella zonaria (2)
180826 Volucella zonaria (1)

With a wing length between 15 and 20mm, Volucella zonaria is the largest British hoverfly and is sometimes known as the Hornet mimic. (There is a very similar species called Volucella inanis but we don’t see them very often in south Wales.) Since arriving in Britain, on England’s south coast, in the 1930s, V. zonaria has made itself at home and has spread west and northwards. During July and August, I’ve seen several of these beauties at Lavernock Nature Reserve and along our local rail trail, a former railway line now a tree-lined foot- and cycling path.

180826 Volucella pellucens (1)

With its large size and black-and-white colouring, Volucella pellucens is a very distinctive hoverfly and easy to identify. You can see why it’s also known as the Great Pied hoverfly. When it’s not feasting on pollen and nectar, it can often be found defending its airspace by hovering around head height along paths and trails. If you stand still, it will sometimes approach to check you out but, once again, it will do you absolutely no harm and move out of your way when you carry on walking.

Fish for lunch again?

Last Saturday we had photos of a Great crested grebe feeding its youngster. Today I spent a delightful 20 minutes watching a Little Grebe (Tachybaptus ruficollis) catch and feed fish to its offspring. Here are some photos …

180825 Little grebes (1)

The adult Little grebe, on the left, is still in its summer/breeding plumage. I’m not sure if it’s a male or female as, from various websites I’ve checked, their plumage appears to be the same, and both parents share the incubation and care of their young. The little one was constantly peeping at its parent for food so the adult was diving in search of the small fish and aquatic invertebrates they like to eat.

180825 Little grebes (2).jpg

This is looking hopeful.

180825 Little grebes (3)

A not-so-small fish!

180825 Little grebes (4)

The youngster waits not-so-patiently for its parent to subdue the fish.

180825 Little grebes (5)

The handover.

180825 Little grebes (6)

Waiting to see if the young one can/will swallow the fish or drop it.

180825 Little grebes (7)

Still waiting …

180825 Little grebes (8)

The little one is struggling with the size of the fish but, at this point, the parent has given up waiting and dived down to find more.

180825 Little grebes (9)

One more big gulp and it’s down! I wonder how many fish it eats in a day.

Bumble- or humble-bee?

180824 bumblebee (1)

Bumble: verb; move or act in an awkward or confused manner (Oxford Dictionary).
Personally, I think it’s a bit sad that the beautiful bumblebee is associated with confusion and awkwardness of movement, though I admit they can seem rather stupid when they fly in the open windows of my apartment and then bump repeatedly against the glass trying to get out again. Most other insects seem able to work out where the open window is.

When it comes to finding nourishment though, they seem perfectly able to home directly in on the next delicious flower. And I’ve recently discovered that the bumblebee wasn’t always so named – it was originally the humblebee, not because it was considered modest or lowly but rather because of the humming sound it makes as it flies along.

Birding at Garwnant and Llwyn-on

We birders of the Glamorgan Bird Club are tough: we don’t let almost constant drizzle put us off a good day’s birding. Heck, we even sit at picnic tables eating our lunch in the drizzle. As long as our optics (bins, ’scopes and cameras) aren’t getting damaged by the wet, we carry on.

180823 birding at Garwnant (1)

And it was certainly worth carrying on ’cause we enjoyed a magnificent day’s birding. We started off with a walk around the trails at Garwnant Forestry in the morning and followed that with a walk through the woodland to check out Llwyn-on reservoir in the afternoon.

180823 birding at Garwnant (2)

I notched up my 187th bird species for the year with the several Crossbills we spotted and heard in various locations along the forestry tracks, and we also enjoyed good sightings of Willow tits and Willow warblers, Tree pipits and Treecreepers, and more than a few Spotted flycatchers flitting in and out from the trees and shrubs in their constant search for the perfect fly snack.

180823 birding at Garwnant (3)

Crossing the Llwyn-on feeder stream after lunch, I earned some brownie points for spotting a Dipper splashing about upstream, and the Spot flies were also active along the river bank there.

180823 birding at Garwnant (4)

As we walked through the woodland at the northern end of Llwyn-on reservoir, we were amazed and delighted by the sight of thousands of tiny mushrooms (probably one of the Mycena species) growing under the conifers, as well as several large groups of False chanterelles. I even had the birders sniffing at a white mushroom to teach them why it’s called The Miller – ‘It smells of dough/flour’, they correctly said.

180823 birding at Garwnant (5)

At the reservoir we marvelled at the magical sight of over 200 House martins feeding on insects above the shallow water – luckily for the birds, the reservoir is beginning to fill again after our recent drought. And the perfect finish to a wonderful day came with the cheery sight of 3 Yellow wagtails grazing together with, perhaps, 16 Pied wagtails in the grass at the water’s edge.

180823 birding at Garwnant (6)

One of the many small streams in the area

Here’s my sightings list for the day: Blackcap, Blue Tit, Bullfinch, Buzzard, Carrion Crow, Chaffinch, Chiffchaff, Coal Tit, Cormorant, Crossbill, Dipper, Goldcrest, Goldfinch, Great Crested Grebe, Great Tit, Grey Heron, Grey Wagtail, House Martin, Jay, Lesser Black-backed Gull, Long-tailed Tit, Nuthatch, Pied Wagtail, Raven, Reed Bunting, Robin, Spotted Flycatcher, Swallow, Tree Pipit, Treecreeper, Willow Tit, Willow Warbler, Woodpigeon, Wren, and Yellow Wagtail. Also seen or heard, but not by me, were Blackbird, Great spotted woodpecker, Lesser redpoll, Sand martin and Siskin – well, I might’ve heard the Siskin but I’m not entirely sure.

Holly blues, the second generation

British butterflies, butterflies, butterfly, Celastrina argiolus, Holly blue, Holly blue butterfly

I blogged about the Holly blue butterfly (Celastrina argiolus) back in May but I’ve since read some really interesting info about this lovely little butterfly and have some new photos to share as well.

180822 Holly blue (2)

My information comes from the book I’m currently reading, which I highly recommend – it’s Wonderland: A year of Britain’s wildlife day by day by Brett Westwood and Stephen Moss. The entry from 13 August is about the Holly blue and answered a query I had about why I’ve recently been seeing so many Holly blues on Ivy plants rather than on Holly.

180822 Holly blue female

It turns out the Holly blue has two generations per year: as their name suggests, the females from the first generation lay their eggs on Holly plants and that’s what the first generation of caterpillars munch on. Then, once those caterpillars have pupated, they emerge as butterflies from around mid July, and the females from that second generation lay their eggs on Ivy, as that’s what the second generation caterpillars eat.

180822 Holly blue (1)

I’ve also been wondering why I seem to be seeing so many more Holly blues this year and Wonderland has the answer to that too:

These fluctuations [in population], over a cycle of five or six years or so, are caused by a small parasitic wasp called Listrodomus, which injects the caterpillars with a long sting-like ovipositor. The Listrodomus grub lives inside the caterpillar, but keeps it alive long enough to allow it to pupate, emerging later from the chrysalis. As wasp populations increase, they reduce the Holly blues. Fewer butterflies mean fewer opportunities for the wasps and so, in turn, wasp numbers fall too. This allows the butterflies to build up again, and that’s why over a span of several years our sightings of Holly blues go up and down.
