I often meet up with Paul Darby ex Wiltshire Wildlife Trust for a pint and a bag of twiglets and inevitably our conversation turns to wildlife. Recently he brought along a couple of his old insect books. In one, entitled Beetles of Britain and Europe – a rather slim Longman Nature Guide dating from 1986, I was intrigued by both the changes in taxonomy and by some of the common names. Many like the common name for the metallic green-gold ground beetle The goldsmith Carabus auratus, and ‘devil’s coach-horse’ for the large black rove beetle Ocypus olens I’m familiar with but others like wool beetle, bladder beetle and and bacon beetle were new to me.

I was recently commissioned to design a nature board for a meadow in Hampshire. I’d hoped to get Richard Lewington to do the illustrations but unfortunately he was too busy working on other projects. I tried another illustrator but sadly that didn’t work out so ended up doing them myself. There were twelve in total including a couple of beetles. The Black and yellow longhorn beetle Rutpela maculata is pictured above. Previously I’ve always used designer’s gouache but after trying a variety of styles and techniques I finally opted for Faber Castell Polychromous coloured pencils and Pigma Micron archival ink on Strathmore Bristol Smooth paper. Surprising really as I’ve never used coloured pencils before.
Until 2004, the blue alder leaf beetle Agelastica alni was thought to be very rare in Britain, possibly extinct although there were some historical records from southern England. Then in 2004 it suddenly appeared again in northern England in the Manchester area, Lancashire and Cheshire in 2006 and Yorkshire in 2014. It was found in Wales in 2013 and in southern England in Hampshire in 2014, mainly around Southampton*. I found it myself for the first time in Hampshire in 2015 near Eastleigh.
I searched for it in Wiltshire in 2016 but couldn’t find it (not that I looked that hard) but of course it was only a matter of time before it arrived. So it came as no surprise when I received an email from David Lawman containing a couple of specimens he photographed in Bentley Wood in south Wiltshire on 11th June. Coincidentally the same day I received an email from Anthony Coles containing a photo of a couple of carded vouchers he found on 2nd and 3rd June in Foxham near Chippenham, north Wiltshire. Although in both instances the photos looked pretty convincing, they were a little blurry (and as I’ve only recently taken on the role of county recorder and I’m not an expert on chrysomelids) I passed them onto David Hubble for a second opinion. Dave runs the Bruchidae & Chrysomelidae Recording Scheme and is the author of the Keys to the adults of seed and leaf beetles of Britain and Ireland and the about to be published Leaf Beetles. Dave confirmed by return, as we all suspected, that they were indeed Agelastica alni.
I’ve not posted for a while. Working freelance has kept me busy and much of my spare time has been spent either keying out specimens, uploading insect and wildlife records, writing reports or more enjoyably attending various insect workshops. At the last one, on Caribidae (Ground beetles) I got chatting to a young lady at the microscope opposite me. Ashleigh works in Edinburgh as a curatorial assistant (Entomology) for National Museums, Scotland and I mentioned that sometimes flying beetles get attracted to my moth-trap. Not quite so welcome are the big, up to 30mm long ‘Spang Beetles’ or ‘Billy Witches’ more commonly known as the Common Cockchafer Melolontha melolontha.
The Black oil beetle Meloe proscarabaeus is a beetle that I’ve looked for on Salisbury Plain before but not found until just recently. It gets its name from its habit of secreting droplets of ‘oil’ from its knee joints when roughly handled. This contains the odourless and colourless toxic chemical compound cantharidin which can cause blistering.
There used to be eight species in the UK but sadly three of them are now considered extinct. In fact two of our remaining five, the short-necked oil beetle Meloe brevicollis, last recorded in 1948, and the Mediterranean oil beetle Meloe mediterraneus, last recorded in 1906, were also thought to be extinct but were recently rediscovered by amateur entomologists in Devon.
Whilst looking for Adonis Blue butterflies on West Yatton Down I discovered this little chap standing on a Hazel leaf. Further investigation revealed it to be a Hazel-leaf roller weevil Apoderus coryli.
It’s a beetle belonging to the family Attelabidae subfamily Attelaninae which are sometimes called giraffe weevils for rather obvious reasons. These primitive insects have a bell-shaped thorax (pronotum) and rather protruding eyes.
The bloody-nosed beetle Timarcha tenebricosa or blood spewer as it is sometimes known from its defensive habit of exuding a bright red-orange fluid from its mouth. This fluid is foul-tasting to predators, seriously irritating the mouth of birds and mammals. Subsequently it can sometimes be seen wandering around in daylight largely unmolested. Read more
Twenty years ago you would be lucky to see this attractive metallic green and purple-striped beetle outside a greenhouse. The Rosemary Beetle Chrysolina americana was first discovered living outdoors in Surrey in 1994. Since then it has become widespread throughout southern England. They are commonly found on aromatic herbs, mainly rosemary but also on lavender, sage and thyme.
This one was found on rosemary whilst I was attending a course on bumblebees in Winchester, Hampshire.
Here’s an interesting beetle I found at Langford Lakes back in May. The Wasp Beetle Clytus arietis is one of the longhorn flower beetles and a convincing wasp-mimic. Both the protective yellow and black colouration and its wasp-like movements give it some protection from predatory birds. If you see it quickly scuttling over vegetation looking for flowers full of nectar and pollen, where it often imitates the distinctive sideways walk of the wasp, it’s not surprising if at first glance this fast-moving insect is mistaken for a jasper.
