Austrian Alps: wildflowers on Zwölferhorn

Daniel Greenwood2 Comments

Zwölferhorn (1522m), Salzkammergut, Austria, June 2025

In mid-June my wife and I visited the Austrian Alps for the second year in a row. We took the cable car from the village of St. Gilgen (featured in the opening scenes of The Sound of Music) to the 1500m heights of Zwölferhorn, so named because according to shepherds down the years the sun sits atop the peak at 12noon (zwölf) everyday.

The views from the top are magnificent, as you would expect from the Austrian Alps, though a bit hazy on this hot day in the Salzkammergut.

Part of the allure of this place in spring-early summer is the wildflowers high in the mountains.

To the south and west the mountains seem to run forever. South-east of here is the famous Hallstatt and the Dachstein Massif, which I will include some long-range images of in an Austrian Alps post to follow.

A view into Salzkammergut

These mountains have been managed in the same way for many hundreds of years – though there were probably fewer trees in the past – which has led to a rich diversity of flowers and their dependent invertebrates. We saw an abundance of both when visiting this time.

The sloping meadows were ‘littered’ with early purple orchids (Orchis mascula). We kept to the paths at all times for both safety as they were steep, and so as not to damage the grasslands. Having a camera in these places doesn’t give me a divine right to trample stuff!

Some of the orchids up close. Early-purple was the only species we saw.

This is hoary plantain (Plantago media) which gave a nice focal point to the alpine meadows.

I was intrigued by this daisy (Asters) as there were signs for arnica in the area. On iNaturalist it’s been identified as willow-leaved yellow oxeye.

This came out a bit out of focus in the wind – it’s the ‘Sussex flower’ of the chalk Downs, round-headed rampion.

This is a new species for me, the slender Scotch burnet moth! Apparently they are native to Britain and much of Europe, and managing to nectar at the same time as mating, impressive.

This photo made me laugh (I’ll explain). I was trying to get the honey bee and the green metallic beetle on the top in focus at the same time, so much so that I didn’t even see the second beetle lower down on the flower, which is actually in focus. This is knapweed, but I’m not sure if it’s a montane species or a variant to the common one.

While this is not a well-focused pic, it does enough to show you what is probably a duke of burgundy butterfly. In the UK it’s recovering but very rare.

The number of butterflies, day-flying moths, bees and hoverflies up here was a sight to behold. It was impossible to photograph anywhere near a reasonable percentage of all the things with wings. There were tens of fast-flying hummingbird hawkmoths on the wing, but getting photos of them would have resulted in falling down off the mountain. Also, we heard a cuckoo up here, which is quite late in the season for them.

The most common butterfly was the small tortoiseshell, another one I know from home. Insert obligatory remark about how it’s not so common anymore! Isn’t it gorgeous?

And to finish, there’s nothing more enjoyable in life than the sight of an unusual hoverfly. This was a new species for me, named on iNaturalist as the white-barred peat hoverfly. That would have been my second guess after Robocop hoverfly.

Here are some landscape images to see out this post of a wonderful walk and afternoon in the Austrian Alps. All taken with a macro lens!

Wasps vs. spiders

Daniel Greenwood2 Comments

Saturday 31st May felt like a passing of the seasons, with spring departing and summer arriving. That could be seen in the invertebrate world, with more summer species out there in my garden.

This post is generally wasps and spiders, with some lovely little bees to calm you down afterwards.

As ever, some of these things are so ridiculously small that without magnification (in my case a macro lens) you (I) wouldn’t necessarily see them.

I should have known it was going to be a good photography day when this little jumping spider appeared in my kitchen sink! The light was rubbish so I’ve had to draw out the shadows and ‘de-noise’ these photos a bit. I’m unsure of the exact species, but I do get an apparently uncommon oak jumping spider in my garden/near the house sometimes, and this may be one.

While we’re on spiders, here’s a wasp – a spider-hunting wasp! I’ve learned that sitting down on the grass by a shrub for 15 minutes isn’t just a forest-bathing exercise, it’s also a good way to allow the life to move around you. One fence post was being explored by this very busy spider-hunter. And then, something amazing happened.

On a vacant fencepost (that’s just how I consider them now) a spider appeared at the top. The spider-hunting wasp saw their moment and burst onto the post, but missed the spider by milliseconds!

The spider-hunting wasps paralyse their prey and then carry them away to a cache. It’s pretty grizzly, but if you think that wasps have been in existence for over 100million years, and spiders, gosh, they’ve been around for over 300million (humans 200k and unlikely to make 1million at this rate), it’s something that’s been going on for a long time. If you’re annoyed about one species of wasp bothering you, imagine how spiders felt when 100million years later a spider-hunting wasp evolves from nowhere!

This is around the time when I begin to notice the very tiny yellow-faced bees (Hylaeus). I’m happy to identify them to that level, and don’t really take it any further.

And here we have some of the ‘best’ images I’ve taken this year. This yellow-faced bee is probably less than 4mm in length. Here it’s nectaring on the stamens of a cultivated garden hypericum. This was grown from a cutting taken from my grandmother-in-law’s garden and is a very good plant for pollinators, though it does need maintaining. I love the way the bee uses the stamen a bit like an Elvis impersonator on a standing microphone. Ah-huh-huh.

Here’s a bumblebee for scale!

I don’t think I’ve seen as many honey bees as in recent years, but there was a glut of them around May. There are reports of problems in the U.S. this year (bit of an understatement, considering who’s running things there).

This solitary bee was visiting the flag iris in our little pond. I do enjoy the bee’s sideways escape. Not sure of the species, might be one of the Andrena mining bees.

I will now make like this bee and leave it there. Thanks for reading.

Aphids watch out! 👽

Daniel Greenwood1 Comment

I’m posting garden macro photos from the 17th and 30th May. I have some really interesting photos from the 31st but that is probably more than one post in itself.

There are a couple of intriguing species I encountered in my garden between mid-late May, one of the very best times to look for our tiny invertebrate friends in this part of the world.

These are by no means great images (I would need extension tubes to increase the magnification) but the species may be an interesting type of wasp. It might be an aphid wasp, which is a group of wasps I haven’t heard of or seen before (there are thousands, even in the nature-depleted UK).

I’ve posted about aphids this year, and have noticed just how good a year they’re having. I listened to this episode of the Food Programme last week on the subject of potatoes, and didn’t realise aphids could trouble potato farmers. Perhaps they need to start gardening for aphid wasps!

We have a tiny pond which supports frogs and is planted with native aquatic plants. One of those plants is flag iris, which the bigger bees love. I enjoy seeing the bees climb through the yellow petals to nectar on the stamens. This bee is probably in the megachile group, perhaps one of the leafcutter species. Someone on iNaturalist suggests it’s a mason bee, so I’m not sure.

I like how leafcutters are in their own world. They often appear after the red mason bees and hairy-footed flower bees have gone, but they seem like they’ve always been there, so focused are they on their leafcutting tasks.

Another welcome sight in the bee world (it’s so much more than honeybees!) are the wool carder bees. I planted this stachys (or lambs ears) for the WCBs in 2020, and they immediately arrived.

Regular readers of this blog may recognise this species from previous posts, who just couldn’t keep out of this week’s post. I used to look like this. These may be an orange-vented mason bee.

This capsid or mirid bug was chilling in the hedge, as they often do.

And finally, those trusty honey lilies were looking their best in the evening light, as their flowering period drew to a close.

Next week we’ll see out May with some pretty epic wasp vs. spider scenes and miniscule bees.

Thanks for reading.

Tiny bees everywhere

Daniel GreenwoodLeave a comment

On 16th May there were lots of small bees to be found in my garden, but more of them later.

This was one of the first sightings of a small purple and gold, or mint moth.

Taking macro photos in gardens introduced me to the capsid bugs. This is one. I’ve seen lots of one species in the hedge this year, they are quite ‘alien’-looking in the sci-fi sense.

Now to the bees. I spotted what I thought was a blue mason bee on the fence, but instead it may be a different mason bee. Compared with the red mason bees, this species, whatever it is, appears later in the spring and lasts longer until the summer.

I love the light in these pics, and it’s all au naturale. Someone on iNaturalist has suggested this is one of the leafcutter bees.

This bee is potentially a little blue carpenter bee. I enjoy the background colours of the rose above…

…and the yellow and cream of the honeysuckle. Backgrounds in macro can make a very big impact on the photo. This is a species of sweat bee.

Finally, I didn’t get this little wasp in focus, but I like these brief encounters with random wasps. It reminds me that there is still huge biological diversity in the UK and the world does not revolve around us.

Bumbling up

Daniel GreenwoodLeave a comment

Onto the 15th May 2025, when the bumblebees were beginning to increase as the workers emerged. But we won’t begin there.

The path to my house is overhung by a self-seeded willow sapling (probably to the annoyance of the postman). One morning I noticed the twigs held a cluster of aphids, tended to by ants.

The ants are probably farming the aphids by providing them with a degree of protection and harvesting the honeydew they excrete. These are probably willow bark aphids but my insect book says there are over 600 species in the UK and many are very hard to identify!

Elsewhere on the willow this little caterpillar was chomping away.

I think this is the same species but I’m not sure what it is. Caterpillars are not a strong area for me.

Moving onto bees, I spotted this bee that had been predated by a crab spider (probably Misumena vatia). I am wondering if this might be a cuckoo bumblebee, a kind of mimic that is in fact solitary and raids bumblebee nests, rather than being part of the community. The second photo is from some time later when the spider had moved their prey around.

A couple of weeks ago I wrote about the Sicilian honey lilies that have been flowering in my garden. The bumblebees were out in force among these flowers. They seemed to find it a bit difficult to access the flowers from below, but they were foraging en masse. This is one of the first times I’ve used the high speed shutter option on my camera, and it has provided excellent results. I’m not sure of the species, another area I need to brush up on, along with the aphids.

This spider is pregnant, you can see the egg sack. I think it’s a fox spider.

Mason bees closing doors

Daniel GreenwoodLeave a comment

Around 9th May 2025 the red mason bees were working to seal their little chambers shut, as can be seen below.

2024 was a better year for these solitary bees in my garden, with far fewer in 2025. Their numbers will naturally rise and fall over the years. They’re important pollinators, especially in agriculture, so helping them has a wider societal impact for people who desire it.

In the first of the hotter spells each year I begin to notice these small bees. They’re usually sunning themselves on the edges of ceramic pots, wooden sleepers or fences. I am fairly sure this is a blue mason bee. They are quite skittish but do often return to the same perch if they can see that you’re not an immediate threat.

Elsewhere in the order hymenoptera (bees, wasps and ants) I saw this unusual-looking winged-insect hiding in the leaf shade. I’ve had to edit this a bit to bring the shadows out, but it’s a species of sawfly. It seems to have two antennae in the shadow, but for the life of me I can only see one!

I noticed the first swollen-thighed beetle of the year perched on the burgeoning fennel leaves.

In taking a few pics of this honeysuckle I noticed that there appear to be little sticky nibs on the flowers. I’m wondering if this is to trap pollen when bees visit, or potentially to snare invertebrates in the carnivorous sense. I can’t find anything online about that, but I now know just how invasive it is in North America.

And finally, the trusty Stachys was close to flowering by the 9th May. It looks very cosy and comfy here, ready for the wool carder bees. What I didn’t know about this plant (known as woolly hedgenettle) is that it’s native to Armenia, Iran and Turkey. I bet it has some very cool insects feeding on it there.

Thanks for reading.

Sicilian honey lilies

Daniel Greenwood2 Comments

May has been a very productive month for macro photos for me, especially in my garden. These photos were taken on 8th May 2025 in that town garden in West Sussex.

We have a flowerbed for growing berries that is also home to these unusual alliums (honey garlic or Sicilian honey lily). On the 8th May they were just beginning to unseal themselves, releasing the flower heads. I have bee-heavy photos of this plant to share of the following days, and this spring has made me realise just how attractive this allium is for bees. The bumblebees can’t get enough! Stay tuned.

The oaks were in full-leaf by this point, this sapling somewhere between the red, yellow and green.

I don’t know what this invertebrate is or was, but I’ve seen it over the years attached to the stems of broom (which had such a good year in 2025). I am guessing it’s a species of moth that has pupated into an adult moth, and that this is the chrysalis. #NoMothExpert.

I think this may actually be the same early mining bee I posted about last week! Not sure.

I really like this photo of a fly (no ID yet). I wonder if that’s some kind of sugary solution on the berries. I enjoy the fly’s awkward splaying between fruit. Why not?

The light was working against me here as our friend was on the underside of a leaf. This is one of the Issus planthoppers. It doesn’t look like it, but the head is in focus.

And finally, the starlings were still feeding the nestlings at this point, quite an tiring time for them. They are one of my favourite birds, but are in serious decline (51% between 1995 and 2016) due to habitat loss and historic use of pesticides. You can help them by not using things like Roundup (glyphosate), by putting out fresh water for them to drink/bathe in, and potentially putting up a nestbox if you can.

Oaks leaves like little fires

Daniel GreenwoodLeave a comment

I’m still dining out on mid-April at the moment, it’s such a lovely time of year.

The broom (Cytisus scoparius) we planted several years ago has bloomed magnificently this year. It’s been a treat to both smell, and to see it attract a whole range of pollinators.

Dandelions have been all over social media recently with the recipes for ‘dandelion honey’. I am reliably informed that it’s jam or syrup rather than honey because you’re not a bee. It’s good that people are becoming more aware of dandelions which are incredibly important for pollinators.

We’ve expanded our berry bed in the garden to include an extra redcurrant, blueberry and gooseberry. Above are the lovely flowers of redcurrant.

My little laid hazel hedge is coming along nicely. These fresh red stems are a welcome sign.

As part of the hedge I’ve planted a couple of oaks that have been in pots in our garden for a number of years. One of the oaks is from my grandmother-in-law’s garden near Epping Forest, the other grown from an acorn from Dulwich Wood. I love the redness of the leaves when they first appear, whether or not these are tannins I would need to check the science.

Elsewhere the sycamore is now leafing. Soon these will be sticky with aphid honeydew. The sparrows and blue tits will be hoovering the aphids up to feed their nestlings.

Speaking of those little devils, our swift box has been moved-into after 3 years of waiting for something to happen. Of course it would be best if swifts were there, but sparrows are also red-listed and their habitat is being lost as people are forcing them out of the eaves. Much of that is probably unintentional, but it’s still something we need to look at.

In the invertebrate world, the droneflies have calmed down a bit and are willing to pose for their macro close-up. This is probably a tapered dronefly (Eristalis pertinax).

This is my first decent set of images of a solitary bee this year. It’s probably one of the mining bees (Andrena) but I don’t have an ID yet.

Another solitary bee species had found its way into our living room. I took a few photos before letting the little bee back out into the world.

When is a wasp a hornet?

Daniel Greenwood3 Comments

I was sitting in my garden when a large, wasp-like insect zoomed into view. It dropped into the skimmia and began nectaring on the flowers.

‘Hornet!’ I called out, but trying to be quiet enough not to spook the insect. I captured these images, convinced it was a hornet, the first I had ever seen in my garden.

When I popped a crude phone photo (not the world class images above) onto iNaturalist I began to have second thoughts. The first suggestions were for a species of wasp, the median wasp. That is now the consensus, and so my hornet drought goes on. But it is a beautiful thing.

My house is quite old, built in the 1840s. The path outside our door is known as a ‘twitten’, a Sussex colloquial name for a little footpath. The path is bricked (like many of them are) and always flushes with spring flowers. Lesser celandine and grape hyacinth are two of the species that enjoy the margins.

Does this rose regrowth remind you of a certain American President?

A few holes have appeared in the lawn. I haven’t seen who created these mini-bunkers but I am confident they’re mining bees of some kind.

The red mason bees have been rather slow to appear this year and many of the bamboo slots are still sealed. Some of the bees have been hovering around the entrances, as above.

I took this photo of two – yes, two – collared doves with my macro lens. Macro lenses usually often can act as a telephoto lens because you need space between you and the thing you’re photographing to ensure you don’t spook the subject. The flag isn’t mine, as you may have guessed if you’ve ever met me or read this blog before 😉

The pansies are doing well in the milk churns, a good place to end.

The magic birch tree

Daniel Greenwood3 Comments

High Weald, West Sussex, August 2024

I had some hours to take one Friday afternoon in August and so headed to my local heathy woodland to seek out some summer fungi.

I found zero mushrooms, but did learn that summer wasn’t quite over.

In a clearing created a few years ago by the removal of non-native conifers, a heathland has flourished. Sussex, like other southern counties, once had far more heathland before it was either built on or converted to coniferous forestry (like this particular site).

This little patch of restored heathland was zinging with insect life, not least on a fallen birch tree.

Enter: the magic birch tree. Or at least sunbathe on it.

I revered it in such a way because it was providing roosting space for one of my favourite subjects – robberflies!

I’ve blogged recently about robberflies’ love of wooden fenceposts and handrails. I suppose a suspended birch trunk is just that. Nature’s handrail.

I managed to get my best ever photos of robberflies here, thanks to the capabilities of my camera, and a little bit of that famous fencepost knowledge.

Robberflies are predators of other flies, but also wasps. The photo above was taken using an in-built function of the camera to stack about 15 photos together to create a seamlessly in-focus image. It worked to great effect here.

Less dramatic was this flesh-fly, one that is actually quite smart in their black and white get-up with red compound eyes.

On the toe of my shoe a hoverfly that looked like a scuba diver was resting.

There was plenty of evidence of burrowing insects in the form of these pilot holes.

I didn’t get to see who lived here. Probably solitary wasps or bees.

What this blog can never express is the sheer number of grasshoppers. Every footsteps sent insects like the one above flying for the safety of a grassy tussock.

The birches were showing signs of autumn and its inexorable approach.
