My faith in the fire

Whilst on my laptop this morning, catching up on the shit show that is world and UK news and having a cup of coffee I noticed this small beetle by the fire place crawling up the wall.


Only my second record of Attagenus pellio aka the Two-spotted Carpet Beetle. Both records have been been from home. The first was beaten from flowering hawthorn down the bottom of the garden a few years ago. This one presumably came down the chimney. A coleopterous Father Christmas if you will. 

A good reminder to get the chimney swept at some point....

I've already used Kiss the Carpet lyrics in a previous post title so went with the equally awesome Burn. Probably the Sisters of Mercy at their absolute height. There's also a very good Radio 1 Kid Jensen session from 83 available too. Too young to have seen them first time around. Had to wait til 1992 before I finally caught up with them. Good though!

Know my name

I had a day at the office today and as the sun was shining I made sure that I took a sweep net and beating tray for a bit of surreptitious lunchtime beetle hunting. It was nice to be out and about and lots of bird song gave it a real spring time feel. Quite a bit of insect activity too, mainly small flies but a couple of Comma were my first of the year

I beat lots of Scot's Pine which revealed only my second record of Eyed Ladybird amongst a few a bits and pieces. Examining the fungi on cut silver birch stumps gave me an aleoch that will need dissecting plus this tiny (1.2mm) Ciidid.

With 9 antennal segments and the cute little horns, I think this is a male Sulcacis nitidus, a new species for me. The larva feed on bracket fungus and the beetle is found in the south-east with some records up in Cheshire too. Given its size I can imagine it may be being overlooked somewhat too. In older literature it is known as S. affinis (Gyllenhal, 1827) or Ennearthron affinis.

The post title comes from a new single by Damefrisør. I first heard it played on 6Music and I have played it quite a bit since. Rather good.

The Ides of March

Last year I switched from producing hand written labels for all my specimens to printing ones. I invested in a laser printer and the resulting labels looked not only neater but it also meant that I could get the size of the labels down to match my new smallest card size of 12x6mm. 

The only issue has been waiting until I have enough specimens to make it worth printing out a set. I usually wait until I have at least half a sheet of A4's worth. I can then guillotine the remaining bit off and re-use by feeding through the manual feed tray.

Anyway, tonight that's what I have been doing. Just need to get the labels on and get them in the right storage boxes now!



I find the process of identifying and carding, rather relaxing and can easily do hours infront of the microscope without batting an eyelid. Can't say that I'm as fond of the labelling!

Yesterday was the Ides of March and so in honour of the auspicious date I decided to give the MV trap its first outing of the year. The result this morning was 5 moths of 4 species. Still, nice to get the season off to a start  

Early Thorn

Oak Beauty

Hebrew Character

Small Quaker
Hopefully just the start of things to come....

Last vacation was the same

So in my searching of the freezers and fridge I found another couple of errant tubes with beetles in. These (as with the previous one) were from a Spanish holiday back in 2017. This was a trip to the Picos de Europa and was somewhere that I hadn't visited since 1989.

In every way possible it was a successful holiday and was a real adventure for the two small kids, with a 24 hour ferry, whales, their first proper mountains and some pretty epic walks. It was so good that having concentrated on the eastern part in 2017 we visited the western section the following year. There was also loads of very cool natural history and a few beetles thrown in for good measure.

So given everything else going on in the world and the anxiety it generates it was rather nice to be looking at this beetle five years on and being transported back to a particular day and a place with amazing scenery and wildlife.






But what of the beetle? What species of carabid was is it? Well I quickly figured out it was in the genus Licinus but not one of the two species that occur in the UK. So that left me scratching my head until I remembered that I had a book of European ground beetle keys. 


I had bought this a few years back but had never really used it. Whilst incomplete for several genera it seemed to have good coverage of Licinus so I gave the beetle a go through the appropriate key.

Quite a big beetle at 14mm it keyed quite easily to L. cassideus. Some online exploration did nothing to dim the possibility of that moniker and so am quietly confident that I have keyed and identified my first non UK species of beetle.

Where will it all end!

The post title originates from the brilliant Foals and the song Olympic Airways, from their first album Antidotes. Enjoy.

Shatter your illusions of love

So I have been going through my freezer looking for any stray sample tubes. Ones that have beetles in and especially ones that I have yet to put a name to. I found one such tube this evening and on first examination let out a fairly audible gasp and a small but firm expletive when I looked at the contents. 


For a split second I thought I might have rediscovered a lost UK species but once I looked at the data label scrunched up in the tube, I remembered finding this beetle on a moss covered boulder, on the edge of a glacial meltwater river in northern Spain way back in 2017.

The staph is in the genus Paederidus which has 44 species worldwide, two of which have specimens apparently from the UK but neither of which have been seen since 1833. 

So which species was this? There are 13 that are known from the Palaearctic and four of these occur in Europe. P. punctiventris occurs in south-west Russia, around the Black Sea (so it's not that one) P. algiricus occurs in Spain and north-west Africa but not from the north coast of Spain so I can rule this out too. That leaves me with P. rubrothoracicus and P. ruficollis both widespread and the two ones supposedly once found in the UK in the dim and distant past.

The species are very similar but differ a little on size (always a difficult measurement with staphs) and in the direction of hairs on the tergites (upper sections of the abdomen).


P. rubrothoracicus should have the hairs directed uniformly diagonally inwards where as P. ruficollis should have them directed untidily inwards almost horizontally.

Pretty sure this is the latter, P. ruficollis. A species that occurs right up to the channel coast so could conceivably occur again over here. 

The post title comes from the closing track of Fleetwood Mac's album, Rumours. Still a great listen.
