Red for danger?

I was minding my own business, head in a tree as often happens, when one of these crazy little dudes flew into me today. Maybe it thought I was a trunk. It rolled a couple of times in mid air, tumbled, then recovered in time to land on a nettle, scrabbled about, righted itself, then turned and gave me the most indignant look, as if its crazy flying was all my fault. These are Red-headed cardinal beetles (Pyrochroa serraticornis), frequenters of shady woodlands, predators on other insects, occasional menaces of the airways.

British beetles, Glow-worm, Glow-worm larva

This was a surprise.

220602 glow-worm larva (1)

I’d just come to the end of a long meandering wander around woodland rides and meadows, finding little in the way of critters to photograph or ponder over, and was heading homewards, stomping up a private road, when I looked down and spotted this bizarre-looking mini-beastie tootling along. It’s a Glow-worm larva and the Wildlife Trusts website has this to say about them: ‘Glow-worms live for up to three years as predatory larvae, living under rocks and hidden deep in grassy tussocks where they mainly feed on snails.’

A new beetle

I thought a shiny green beetle with red ‘buttocks’ would be easy to identify – I should’ve known better. It seems the Malachite beetle (Malachius bipustulatus), named after the bright green mineral its colour resembles, can be mistaken for a similar beetle Cordylepherus viridis, though the thorax and head shapes are a little different. Looking at those features, and checking the Welsh records for both beetles, I’m fairly sure my find is a Malachite beetle but I’ll update this post if I’m proved wrong.

As busy as a beetle

beetle, British beetles, busy as a beetle

An idiom we often use to describe someone who has a lot to do is ‘as busy as a bee’ but have you ever watched a beetle going about its everyday chores? They can be just as busy as bees.

With over 4000 species of beetle in Britain, it’s almost impossible to identify them with examining their genitals (!), so I haven’t even tried to put a name to this little one. I simply enjoyed watching the sun catch its glimmering carapace as it beetled busily along.

Here’s another find from my visit to Aberbargoed, though not from the grasslands. My friend and I also had a good wander around the adjacent spoil tip, a huge reminder of the coal mining industry that used to dominate much of the Welsh Valleys and now home to an amazingly diverse range of flora and fauna.

Last week’s walk produced my first ever Green tiger beetle (Cicindela campestris), a species I’ve wanted to see since marvelling at the wonderful photos I saw on Liam Old’s Twitter feed. (Liam is the founder and force behind the Colliery Spoil Biodiversity Initiative, which promotes the environmental value of spoil tips and the immense biodiversity these sites support.)

beetles, British beetles, ground beetle

First, I read that there are around 4000 species of beetle in Britain. But I remained optimistic and figured I might be able to narrow it down by location – it was bumbling along on the ground, so perhaps it was a ground beetle (the Carabidae). Next, I read that there are 374 species of ground beetle. But I continued to be optimistic and thought I might be able to narrow it down by shape or colour. Then, I looked through the gallery of photos on the Coleoptera website and also on the Nature Spot website, and realised that these creatures are a whole lot more difficult to identify than I first thought. So, here’s a beetle, a rather gorgeous beetle with a metallic green sheen, but a beetle none-the-less.

This Spotted longhorn (Rutpela maculata) was happily minding its own business, feeding on the umbellifer flowers growing along the edge of a woodland ride, as is its wont, when …

And so the necessity of life as a beetle takes over, the need to reproduce, to continue the species. Lunch might have to wait.

I don’t see many beetles, perhaps because I don’t spend enough time looking for them, but I could hardly miss these ones, because there were hundreds of them.

200615 celery leaf beetles (1)

I’m not entirely sure what they are and there are many species of leaf beetle that look very similar but, as these were munching on umbellifer leaves – possibly hogweed (I’m not good at identifying umbellifers either!), I think they might be Celery leaf beetles (Phaedon tumidulus).

As well as munching on the correct type of leaf, these beetles were about the right size (tiny, just 3-4mm), and, although they have lines of dimples on the elytron (the wing covers on the abdomen), they don’t have any on the centre of the pronotum (the thorax), which also fits with Phaedon tumidulus. However, I may have got the ID wrong, so do let me know in the comments box if you can positively identify these hungry creatures.

Iridescent Green dock beetles are out in force now on the Dock plants in one of my local parks. I’ve blogged about these gorgeous mini-beasties before (Green dock beetles, May 2016) so today I’m just going to share a few photos. Keep an eye out for these on your exercise walks, and don’t forget to check carefully under the holey leaves for eggs and their little grey grubs.

#365DaysWild, British beetles, Longhorn beetles, Rutpela maculata, Slade Wood, Spotted longhorn beetle

I thought I’d found a new variety of longhorn beetle when I spotted these creatures at Slade Wood on Monday but no. It turns out the yellow-and-black markings of Spotted longhorn beetles (Rutpela maculata) are quite changeable and these were just variations on a theme.

190724 spotted longhorn (1)

As their larvae inhabit rotten wood, the adult beetles can usually be found near woody areas, on hedgerows and along woodland rides, where they enjoy nectaring on umbellifer flowers.

I’ve just been reading that the adults only live for a few weeks between May and August so eyes peeled – you haven’t got long to spot these little stunners.
