Beetling in vane

Desperate times call for desperate methods.  So today, I decided to build a couple of flight interception traps (aka Vane traps) from used cordial bottles. I cut two windows out and used one of the cut pieces to create a baffle to intercept passing insects.

I hung them by dead or dying apple trees at the bottom of the garden. The idea is that beetles and flies flying in to investigate this dead wood, hit the baffle and then drop into the liquid at the bottom. In this case, water with a drop of washing up liquid. Given that I'm checking the traps every day or so, this should suffice. If I was leaving things for longer then I would pop some monopropylene glycol in instead.

The temperature is still very cold so probably not much chance of stuff at the moment but will hopefully deliver the goods over the coming weeks of isolation and lock down.

I also swept this beetle from grass just before giving it a mow. Looked different to the Bruchus rufipes I normally see. I find the key to this group really tough so ended up posting it for others to help with. It appears to be Bruchidius varius. This species was added to the British list from a single specimen found in East Sussex in 1994.  It is now widespread in south east England.

I'm still trawling through the backlog of 2019 beetles so will post some of the more interesting or novel (for me) records in a future post.

Another day, another beetle. The elaterid Kibunea minuta was out in numbers today. Climbing up un-mown grass in the garden. At only 6mm it's one of the smaller click beetles I've encountered.

The small second and third short and rounded antennal segments are a diagnostic feature for this species.

There was some confusion on my part as the species known here as Kibunea minuta  was transferred to the genus Limonius by Cate (2007). Leseigneur & Mertlik (2007) showed that two closely related species are present in Europe and can only be differentiated by the male genitalia and that all British material has so far proved to be poneli. L. minutus appears to be a species with a more southerly distribution, although it could turn up in Britain.

Confused? I still am. For now we'll continue to call this Kibunea minuta !

The only thing you gave me was the boredom I suffocated in

So I chanced a supermarket run early doors this morning and as I was driving, listening to the radio, the Manic Street Preachers' Motown Junk came on. I loved this song when it came out, I was 17 and I saw them play it in a small sweaty pub in Hull about a month later. I seem to remember it being a rather edgy gig.

It also furnishes this post with a title. I am doing my best not to get too bored whilst stuck at home. So late this afternoon had another poke around the garden.

First up was a quick sweep of a patch of Green Alkanet. It turned up this hairy fella. A quick glance at my recently acquired caterpillar guide and I'm reasonably sure it's a Ruby Tiger. Good to see as they appeared to have a poor year last season if my trapping data is anything to go by.

Next was a hoverfly sticking lowdown in the vegetation. There was a gap between the eyes making this a female and I think the grey spots on the abdomen make this Platycheirus albimanus.

Then there was this bug that I was pretty confident that it was a Drymus species but not beyond that. Apparently it's D. sylvaticus (thanks, Skev).

I also found a few staphs in some ejected rabbit nest material. These will need a closer look and dissection before I throw in the towel in and give up.

And here's the song that transported me back 30 years.

The first five hundred

Feeling at a loose end this afternoon I took 30 minutes to poke around the garden. I was struggling to find much of interest and my enthusiasm quickly waned.

A last ditch effort with the vacuum sampler turned up a few of the usual suspects but in amongst these was something I couldn't put a name to. I knew I hadn't seen it before and despite the small size was an easy one to identify.

The staph Metopsia clypeata. Adult beetles are active from March until October, and occur among decaying organic matter in tussocks, leaf-litter, dung and fungi and have been recorded nocturnally at sap and under bark. Mine was from a bit of my lawn with yarrow and other plants. Probably some decaying material in there too.

Entering the record I realised that this was the 500th species of UK beetle that I have identified (there are many others sat in the freezer waiting for a name...). My hope had been to try and see another 200 by the year end and hit the 700 mark. I've already seen about 50 new species so far this year and was hopeful of reaching that target.

I'm pretty sure that won't happen now as I'm obviously restricted to my garden for the forseeable. There is obviously still plenty to find I will just need to be resourceful.

Last chance saloon

Lock down is undoubtedly coming. Given the stupidity seen at various places this weekend, the government is going to have to act. You would have to be blind to not to see this coming.

So, all that being said I took the kids for a run around RSPB Lakenheath yesterday. 10 cars in the car park and everyone keeping their distance. Didn't get within 20 metres of anyone else.

The weather was cold but glorious, and the sun had real warmth and strength. And nature was on the move. This Pterostichus niger was walking along the main track and there were plenty of flies on the wing plus brimstone and peacock butterflies.

Poking about in fallen poplar logs I found a couple of Carabus granulatus getting ready to leave their winter hibernation sites.

There was also this Pied Shieldbug under one log looking rather resplendent in its monochromatic loveliness.

What are we all going to do whilst restrictions kick in? Firstly, find a way to live life with a restricted geography. All the grand plans for 2020 get ditched by default and new ones will have to be created. I suspect that I'll expand my horizons beyond beetles and look at other invert taxa and try out some new forms of trapping. Get a couple of vane traps out and try and pick some offal up from the butchers when I'm in for food to bait for carrion feeding beetles.

I'm one of the lucky ones. I have a reasonable garden and options up my sleeves. I suspect that my love of natural history will stop me going mad.

At least I hope so.

My life sucks too now

Four years ago I saw this post from Graeme Lyons and never in my wildest dreams thought that it was something that I'd ever contemplate. Fast forward to 2020 and I have a Black & Decker GWC3600 L20-GB 36V Blower Vac suction sampler sat in the car and all ready to go. 

These are weird and confusing times but given that restrictions on personal movement are only going to get stronger I decided that I should get out for a walk and a poke about whilst I still could. I decided to visit the Devil's Dyke to the east of Cambridge. I only saw two other souls the entire time I was there and both of those were at a distance. 

This site is an ancient earthwork designed to restrict movements of people before the fens were drained. It runs from the village of Reach in the north to south of Newmarket. Unusually for Cambridgeshire, because of the height of the excavation, you also get a view.

The site has extensive chalk grassland with a mixture of areas with bare ground as well as some bits that have gone over to scrub.  Not something you find much of in Cambridgeshire (chalk grassland not scrub!).

Sheep graze much of it keeping the vegetation down to a low level. Work is ongoing in some places to clear the scrub to allow grazing to return. There are a few botantical rarities (for Cambridgeshire) here but my ability to ID on vegetative state only is too poor to have given that a go on this visit.

So given that it's so light and portable I decided to take the suction sampler with me and give it a quick whirl whilst there.

Locked and loaded. Ready to go (sans bag)

It was a joy to use. It found stuff that I would just never find by the usual direct method of grubbing around. Bloody loads of ants. No, loads. Really.

Most numerous beetles were Syntomus foveatus and Phaedon tumidulus but the best species was a few individuals of Mantura matthewsii. This flea beetle I think is a leaf miner on rock rose and is not that often encountered, probably because folk aren't out in the right place with a sucker....

I suspect  I will now just take this contraption with me everywhere now. Can't wait to let it lose on other plants and habitats.

A face only a mother could love

In amongst all the uncertainty, worry and stress of today I managed to grab a late afternoon walk at work. The sun was out and the blossoming trees were alive with bees and flies.

It's amazing how the mind resets as soon as it's exposed to nature. I can almost feel my blood pressure dropping as I take it all in. Sterling stuff.

I paid a quick visit to a favourite log pile in the hope of catching sight of a couple of species. I wasn't disappointed as on a first glance I clocked a Platyrhinus resinosus doing its best to look nonchalant.

What a beast. Just love their grumpy faces.
