Raindrops on noses. And blackberries.
A busy week, as ever! Trying to recover from Birdfair, to get stuff done both at work and outside. At Lorton, I had a woodland wander as I took some children searching for beetles. Typically, we also found some other cool stuff to be fascinated by: a tiny delicate mushroom in the middle of the path, a few different types of harvestman and LOTs of slugs, snails and worms!
- ID Tip: Both spiders (Araneae) and harvestmen (Opiliones) are arachnids (Arachnidae). To tell whether you’re looking at a spider or a harvestmen, the trick is to look at the body. A spider has distinct body parts – i.e. you can see easily that is has a thorax and an abdomen. Whereas in a harvestman, the thorax and the abdomen are fused together and it looks like it has just one body part.
Later in the week, I went on a meadow meander to find a Wasp Spider (Argiope bruennichi). Sadly, the one that I’ve photographed a lot recently was no longer in place. I think maybe the cows wandered through and trashed its web. However, I still managed to find one, and even saw her spinning a grasshopper (I know it is a female as the male Wasp Spider is brown and smaller)! No photos or videos of that sadly as she was too quick for me! But I did get a photo of her beginning to munch on it. The meadow meander turned into a general nature walk (the best kind of walk!), as we examined grasshoppers and crickets, pried open a hatched oak gall (to unexpectedly find an earwig nymph inside!) and I found a new species for me, the Red-legged Shieldbug (Pentatoma rufipes). [PSL: my 12th Hemiptera species]
Also on the walk, I came across this interesting Hymenoptera in a patch of clover. I think I’ve decided it is an ant species (Formicidae), but that is as far as I’ve got!
- ID Tip: Hymenoptera are the group of insects that include bees, wasps, ants, sawflies and related insects. I knew it was a Hymenoptera because (a) it has two pairs of wings ruling out flies (not easily seen in these photos I’ll admit) and (b) it has long antennae which again ruling out flies which have much shorted antennae. I knew it wasn’t a sawfly (Symphyta)) as they do not have a distinct waist, but the one in the photograph does. After this, I am not sure of the exact ways to tell them apart, but my instinct was saying ant (Formicidae).
Saturday evening saw a mad dash down to Lodmoor, to scout out the area behind the tip. Why you might ask? Well, a Long-tailed Blue butterfly (Lampides boeticus, apparently also known as the Peablue which is a lovely name!) had been seen there! The weather was atrocious for butterflies, and a not great for me either I might add – I got soaked! However, I still had a hopeful look around. I saw plenty of wildlife (including a couple of butterflies when the weather had a break from pouring water down on Weymouth) – but no Long-tailed Blue! Oh botheration! I consoled myself with blackberries (covered in raindrops as previously mentioned) and taking photos of the other wildlife, including SIX Wasp Spiders, a very obliging Common Blue butterfly (Polyommatus icarus) and a rather wet male Red-tailed Bumblebee (Bombus lapidarius) trying to shelter from the rain.
Back at Lorton for Sunday, a rather grey and damp day, though no downpours. I had a bird-themed weekend running which meant one of my favourite activities – owl pellet analysis! I.e. lets take apart some solidified owl vomit to look at the bones of small mammals. Sounds grim, but it one of the best things to do I think. You end up finding some fantastic things and learning a lot about anatomy at the same time.
- ID Tip: When dissecting owl pellets, one of the key bones to look out for is the skull (and lower jaws). By looking at the size, and the teeth, it is possible to identify small mammals down to species level.
- E.g. A skull with no gap between the molars and incisors will belong to an insectivore. If the teeth are all white, it is a European Mole (Talpa europaea). If the teeth have red tips to them (yes, you read that right, red-tipped teeth) it is one of the shrew species (Soricidae). You then look at the end tooth and the number of cusps (bumps) on it, which then tells you which species it is.
- Hm, maybe I will write a whole blog post on owl pellet dissection and small mammal bone identification? Interested in reading such a post? Let me know!
The end of my (working) week had a thrilling conclusion when a visitor asked me about a caterpillar they had seen. My interest was piqued, I do so love Lepidoptera and their caterpillars. I went out, armed with a caterpillars book and my camera. Turns out I didn’t need the former as I knew straight away what species it was. I have seen plenty of photos of this species on Facebook and Twitter, but never seen one as a caterpillar in the wild myself. Until today! The wonderful and beautiful Elephant Hawk-Moth (Deilephila elpenor), pink and green as an adult (PINK and GREEN!!), brown, smooth and seemingly with many eyes as a caterpillar (the eyes are to scare off predators!). Look how awesome it is!!
Heading back to the centre (my mid-afternoon snack was waiting for me after, mm chocolate cake), I yelled out “Caterpillar alert!” as I almost stepped on another caterpillar. Slightly smaller, and with many more hairs, I could tell what this one was straight away as well, the Fox Moth (Macrothylacia rubi) caterpillar!
In other news:
- I wondered whether to write a post about the badger cull, and its extension into Dorset. But I don’t need to, because the Wildlife Trusts have written a superb news piece which covers everything (and a bit more) that I would’ve said. Please do read it, and speak to your local MP / Westminster / everyone about why the badger cull should not occur.
- Dorset Wildlife Trust was awarded TWO bronze medals for our float at the Weymouth Carnival! Well done to Vicky who was our co-ordinator!
- I only have a month and a half left in Dorset! Which is rather scary as there is still so many places I want to visit and things I want to do!
- I’m recalculating my Pan-species List, as I’ve managed to get myself all confused – the online version and my notebook have different numbers. D’oh!
- I’m doing rather well on my 2015 Wildlife Resolutions, but have got a fair bit of work ahead of me to ensure that I tick them all off!

What an interesting week! It takes a special person to see the world at the level of insects, and delight in that world. Thank you.
Thank you for your lovely comment! I do find insects very fascinating, and their variety (even within one taxonomic group) is astounding! Of course, I still love mammals, birds, plants, etc but as mentioned, insects have a lot of variety to keep me amused!
Fascinating as always – blog post on owl pellet dissection sounds like a great idea! 😀
Thanks, and I shall start drafting one – a post for winter perhaps when I’m not seeing so much wildlife?
Sounds like a great idea to me! 😀
