In a room with a window in the corner

I have a window in my kitchen that faces east-north-east. It gets the morning sun and helps warm up the downstairs of the house on days like today. It also is quite good at catching and holding insects both on the internal and external faces.

Some insects must come into the house via the open patio doors and end up here whilst they try to escape. For one beetle species Anthocomus fasciatus, the only place I have recorded it has been on this window. And that has happened twice now, with both times in May. This one appearing last week.


Today, I was cooking dinner when I happened to glance outside and caught site of a dark smudge on the glass. A closer look and I saw it was actually a pair of moths having some fun on the outside of the glass. They were small and vaguely pug-like.


But when I went round and had a gander from the outside I saw they were in fact Small Dusty Waves Idaea seriata. The book says a first brood emerges in June-July, but I don't normally record these in the garden trap until August.


Whilst walking back in the house I plucked a beetle from the air as it flew into the house via the patio doors. Turned out to be the first Glischrochilus hortensis of the year. Must have liked the smell of my cooking. This is the only one of three species in this genus that I have seen. It often appears in pub gardens attracted to the boozy smells and I also get them turning up in late summer when I am pressing apples for cider. Attractive little things.


The post title inspiration is rather timely. Forty years ago today Ian Curtis committed suicide. I was too young at the time to have heard of Joy Division. It was probably another nine or ten years before I came across their music but it immediately hit a chord with me. There was something about their sound that encapsulated the atmosphere of walking through the streets of a northern city, in my case Hull. Something of the concrete and the metallic. All industrial, nothing organic. I still feel that way listening now...

And here's a story about being free

Well, it's all relative isn't it. This week, the lockdown restrictions lifted ever so slightly, so Saturday evening saw me in a field on the Cambridge-Suffolk border in some chalk grassland with a moth trap. Nothing stupid, nowhere too far, and not another soul in sight. I just hope others do similarly and that we don't see another spike in infection rate. Just thinking about being in lockdown during winter puts shivers down my spine......


The temperature was supposed to remain in double figures until gone midnight but it got colder much more quickly. Consequently I saw the sum total of 2 moths plus a few beetles but it didn't matter, it was nice just to be out somewhere different. Listening to the sounds and taking it all in.

Today, I took the kids out of the village and in the car for the first time in two months. We drove all of 3 miles to have a walk and ended up in an old fenland site in amongst the arable. There were a few others out there too but not many and not enough to distract from the relative isolation. There was lots of flowering hawthorn and some dead wood scattered about and the dragonflies and damselflies were patrolling the water margins in numbers.



With two kids in tow there's never enough time for natural history but I did manage to beat a few bits of foliage and was rewarded with a new longhorn species. One that I really should have seen before...Stenocorus meridianus.


There were also lots of the weevil Archarius salicivorus on Salix, which I don't think I'd ever really appreciated how lovely and delicately patterned they are when viewed from the side. They also have a proper weevily proboscis on them.


I also caught one of my favourite beetles, Ischnomera cyanea. Not sure why I like them so much, I guess they are subtly beautiful with the their sculptured elytra and non-garishly metallic colouring. I also see them regularly beating hawthorn but not so often that I become blase about them.


Up close the colour is even more impressive although this image doesn't really do it justice.


Back home I got a garden tick in the form of Chrysolina oricalcia, which was sitting atop a blade of grass while I pulled a few weeds. Although widespread it's another one that I don't see that often. It feeds on umbellifers, so I guess may have emerged from nearby.


And here's the blog title inspiration. A good one to listen to on a sunny day with slightly increasing possibilities....

Well boredom is a killer

Another couple of busy days with lots going on. Not much time to get outside and things were getting a bit predictable. Being mindful of what the Young Fathers said (hint: post title) I made sure I had half an hour in the garden at lunchtime to try and mix things up.

Rather than gaze at the heap I decided to beat the few remaining and pretty much gone over hawthorn blossom. There were all the usual suspects but two species caught my eye and for different reasons.

The first was a beetle which I knew was new to me. It was distinctively patterned and I immediately recognised it but couldn't for the life of me remember the name, just that it was a Ptinidae. A quick look at the web confirmed it as Hedobia imperalis. It is found on decaying wood, where its larvae feed and the adults are often found near old Hawthorn hedges. It is relatively common across southern England.


The second species was a large sawfly which I thought was probably worth trying to identify. I've only IDd a couple of species before and this looked like it might be an easy one. I worked out from images that it was in the genus Tenthredo and with help from AndyM and SimonK on Twitter, I now know it's Tenthredo temula



The key features are black antennae and black scutellum, with the clypeus pale and uncoloured.


The tergites (topside bits of the abdomen) should be black on 3 and yellow on 4 and the sides of 5. I've marked the image up below and numbered the tergites. All seems to be present and correct.


It's a common species but not one I've encountered. Anyway feel a bit less bored and a bit happier after a new beetle and a foray into a new group.

This song would perk anyone up. Great video.

Not much doing

Had a bit of a natural history lull the last couple of days. Work and other stuff has meant very little time to get outside and stare at things or tackle some of the identification backlog I have waiting for me. My carrion trap has failed to attract anything more than flies and the hawthorn in my garden has pretty much gone over.

However I did manage 20 minutes in the garden at lunchtime. There was a cool wind but in sunny sheltered spots it was rather pleasant.

There were a fair number of  Cocksfoot Moth Glyphipterix simpliciella sat around on various plants. They are tiny things but despite their ubiquity at this time of year they are always worth a closer look. Stunning little things. Trying to get a focused shot in the wind was nigh on impossible.


I also beat this caterpillar off some hedgerow elm and it gave me a chance to have another look at the recent Caterpillar field guide.


I managed to mess up the ID fairly easily before being put right (Thanks Graeme). This is a Common Quaker caterpillar and probably one I will regularly encounter, given how common it is.

Hopefully the weather and my enthusiasm will pick up over the next few days.

Tiny rhino

I was checking out the UK Beetles Facebook page yesterday morning over breakfast and noticed a post about the increase in the weevil, Rhinocyllus conicus.

Originally this species was native to southern and central Europe, western Asia and North Africa. But in recent decades it has spread north and has made it to the U.K. Over here it was first restricted to southern coastal areas but following a recent and continuing expansion possibly due to a warming climate it is now reasonably common across England and Wales.

It was also used a biological agent in Canada during the first half of the 20th century to control introduced and invasive thistle species. It was successful but then turned its attention to native flora. Another example of humans underestimating the adaptability of nature.

Anyway, I saw the post. Looked up the species, discovered the above then went to the back of the garden where I pointed my suction sampler at a couple of ground height thistle rosettes with no particular expectation.

Thirty seconds later.....

Bingo.


It's a big weevil. This was approaching 6mm. I found two individuals from a single sample. So must be pretty common here I would imagine. Another new species for me and a particularly easy one to both find and ID.

Green eyes

Before Christmas I got hold of an Olympus TG-6 camera. I'd seen and heard all the fuss around its in-camera focus stacking and its amazing close focus abilities and I thought that I would be able to put it to good use especially on taking shots of beetle specimens.

Like with any camera, it's isn't a quick fix to getting amazing images. You need to learn what it does and how to coax the most from it. To be honest since I got it I haven't really given it much attention.

However, this week I've at least been taking it out and seeing what it can do. First off, I decided to beat a bit of hawthorn to see what I could point it at.

There were lots of Grammoptera ruficornis running about and I managed to grab a couple of shots where most of the beetle was in focus


This cranefly proved to be exquisitely beautiful viewed close up. Just look at that eye! What a perfect shade of green. The stripe down the abdomen and the aforementioned eye colour make this Tipula vernalis. (Thanks to Tristan, Calum and Ryan on Twitter for the ID).



I also had my usual sieve of the garden heap to find that a whole load of Lesser Earwigs have turned up. I always think 'staph' when I see them until I notice the end of the abdomens. They kept running about but I manage a shot or two that were vaguely recognisable.



Still lots to learn an have only dipped my toe into what is possible with this bit of kit. For specimen images I really need to sort out a suitable lighting setup, but we'll get there. Will just have to keep on practicing...

Today's title inspiration for you.

Warm grass around you

So I added fresh grass clippings to the pile on Saturday and popped to have a look at lunchtime to see what was happening. The grass and bacteria were doing their thing and it was too hot to put my hand in to any real depth. In the outer cooler layer there was a fair bit of beetle action. Mainly staphs such as Lithocharis ochraceaPhilonthus varians, P. jurgans and P. discoideus.

On the first sieve, this monster (15mm) turned up. Ontholestes murinus. It's the first time I've seen one in the UK. They are absolutely stunning creatures and move incredibly quickly, much more so than other big staphs I've seen. They are predators and it will have been scouring the heap for prey. The other species in this genus tessellatus is even bigger and has pale legs. I'd never realised before that they have patterend scutellum. I'm amazed at the stuff that keeps turning up.


Other recent additions to the garden list are a rather battered Leptacinus pusillus sieved from the heap.


The rather lovely Rugilus angustatus. This is confined to the south east and is much bigger than the more commonly encountered members of this genus. They all have the amazing narrow neck though. I've only seen this once before at Wicken Fen.


Last but not least is this Lobrathium multipunctum which was running around the the freshly dug earth of my new pond. I've only seen this once before in north Norfolk on soft cliff whilst twitching Nebria livida. It apparently likes very early successional habitats, of which my pond is prime example! How the heck did it find it though?


Today's post title inspiration comes from Underworld's third album Beaucoup Fish. It reminds me of living in Australia and seeing parrots everyday. That all seems like a long time ago....
