Dinosaurs are wildly popular, especially with children. Think of all those films, books, cartoons and soft toys. Is it because they belong to a world long past, full of extraordinary creatures we shall never see again? At any rate, the attraction doesn’t seem to extend to their modern-day descendants in the same family – crocodiles, snakes, lizards and iguanas. ‘Ugh, reptiles – slithery, dangerous creatures, more horror film material than Disney!’ Well, that’s partly right since they are indeed slithery – the word ‘reptile’ means ‘creeping thing’ but in Britain, at least, only one of them (the adder) is at all poisonous, while the others are entirely benign and all of them are interesting.
We have six species of reptiles in this country – so there’s a quiz question, can you name all six? They comprise three snakes, two lizards and one other that looks somewhat like a snake but is actually a legless lizard – a slow worm. You can tell a slow worm from a snake since it has eyelids and can blink. It also has a much smoother skin, in which the scales are not overlapping and don’t feel rough to the touch. Finally, slow worms have no separate ‘neck’ so do indeed look like a very long worm.

There have always been popular misconceptions about slow worms. Shakespeare usually gets his wildlife references right but in Macbeth he has the witches casting a ‘blind worm’s sting’ into their toxic brew, a double error since they are neither blind nor do they sting. They do have one unusual anatomical feature, however, which accounts for their scientific name fragilis. They have various natural enemies like hedgehogs, badgers, magpies and domestic cats and have evolved a trick whereby if the would-be predator grabs them by the tail they can detach these and leave their captors grasping just this bony appendage – still wriggling independently. If they survive all these hazards, slow worms can live to a great age – over 50 years has been recorded. They also enjoy an impressive sex life, in which a couple can be entwined together mating in leisurely fashion for some ten hours at a stretch, so to speak.
Slow worms used to be quite common round here, and were welcome garden visitors, feeding on slugs and snails and living unobtrusively in damp corners and under compost heaps, but their numbers have declined sharply in recent years. Help may be at hand, however. A local developer needs to relocate some from a building site before he can get permission to proceed and we’ve made a bid for them. So there could be some coming your way, slowly of course.

This medium-size brown dragonfly has four characteristic spots on the wings each side. You can just about make them out in this blurry photo, taken between SS and East Lane. Lots of other dragonflies emerging just now but this one is relatively easy to distinguish.

Village Voices Nature Note: Web Sights
When you see a spider do you go Oh, Ugh or Aaaaaaaaarh? Wherever you are on that ladder of reaction, let me try and talk you down to a rung where you might just say Hi oreven Wow! Fear of spiders (arachnophobia) is quite common. It could be a primitive instinct evolved when our distant ancestors lived in caves in Africa and might have trodden on seriously poisonous spiders. Or maybe we learn it as children from nursery rhymes like the one about Little Miss Muffet, who was put her off her curds and whey by an abseiling spider. But relax. None of the common spiders in the UK are dangerous to humans. Certainly not those big house spiders that can appear overnight in the bath or dash across the living room floor at an impressive top speed of half a metre a second; nor the Daddy Longlegs that get into odd corners of rooms and twizzle rapidly in their untidy webs; nor all those tiny spiders that balloon around on invisible filiaments of silk – on the contrary, these are the ‘money spiders’ that are supposed to bring you good luck.

Most of the UK’s 650 species of spider – bet you didn’t realise there were so many – live outside anyway. Among the wonders of autumn are those soft , misty mornings when you go out into the garden and see a perfect spider’s web outlined with beads of dew. The architecture of these silvery webs is breath-takingly beautiful. The spider first puts in the spokes to establish the structure and tether it securely to its moorings, then adds the complex spiral strands with a special sticky kind of silk that will trap unwary insects. The spider herself has anti-stick feet – all eight of them – to navigate the web. As a construction material the silk has extraordinary properties. It’s five times stronger than steel, weight for weight, but so light in density that a strand of spider’s silk stretched right round the earth would still only weigh the same as a bag of sugar. You can make bullet-proof vests from spider’s silk. It has medical uses, too, as a gentle anti-septic for binding wounds. Miss Muffet may in real life have been the daughter of the famous sixteenth-century naturalist, Dr Thomas Muffet, who discovered this property. Shakespeare knew about it anyway. In his Midsummer Night’s Dream he refers to the curative powers of one of Titania’s attendant fairies called Cobweb (‘Cob’ is the old name for spider). And we honour spiders, at least metaphorically, by naming one of the most important modern inventions after their magical creations – the World Wide Web.

Diving beetle

A large Diving Beetle unexpectedly crawling around in my moth trap this morning. They really are huge – one-two inches – and quite fierce-looking. They sometimes fly around at night in search of water so I put it in my pond, where it seemed quite content.

Village Voices Nature Note: the Humbler Creation
01 Oct 2021
There’s plenty of public support for protecting charismatic species of wildlife like golden eagles, beavers, red squirrels, swallowtail butterflies and oak trees – even domestic alpacas, just recently. But what about the humbler creation, as the hymnist put it, of insects, beetles, and worms that actually make the world go around? Especially worms. Worms have traditionally been regarded as the lowest form of life. The word itself comes from the Latin vermes from which we get vermin, and to call someone a worm suggests they are beneath contempt. But as any farmer will tell you worms are critical to the health of the land. They devour and recycle dead vegetation, and act as tiny ploughmen to aerate, drain and fertilise the earth. The richer the soil the more earthworms there will be in it, so those worm- casts on your neatly cut lawn are more like compliments than disfigurements. It’s been estimated that in an acre of good pasture there may be a greater weight of worms under the soil than there is of live stock above it.
All the great naturalists in history have praised worms. Aristotle called them the intestines of the soil, while Charles Darwin studied them for over 40 years and observed, It may be doubted whether there are any other animals which have played so important a part in the history of the world. My favourite worm quote, however, comes from the peerless Gilbert White, curate of a small village in Hampshire, whose Natural History of Selborne (1789) is said to be the fourth most published book in the English language (after the Bible, Shakespeare and John Bunyan). White is the spiritual father of all today’s nature diarists (including me) and Selborne is the record of his daily observations in his tiny parish, which he rarely ever left. Here he is extolling the worm and making a very modern point about the interconnectedness of all life:
The most insignificant insects and reptiles are of much more consequence, and have more influence in the economy of Nature, than the incurious are aware of; and are mighty in their effect... Earthworms, though in appearance a small and despicable link in the chain of nature, yet, if lost, would make a lamentable chasm. For, to say nothing of half the birds, and some quadrupeds, which are almost entirely supported by them, worms seem to be the great promoters of vegetation, which would proceed but lamely without them.
In some cultures we become part of this chain too by eating worms – the Maori traditionally regarded them as a great delicacy; and in most others we willingly submit to the reverse process on death ...

Village Voices Nature Note: far away and long ago
05 Apr 2021
There’s a lot of excitement about this Perseverance mission to Mars. The technology is amazing and the information we are getting back is remarkably detailed. For example, the night-time temperature there yesterday was a bracing -980F. They’ve equipped that extraordinary Rover vehicle to search for signs of past life. If they find any, it’s likely to be in the form of fossilised microbes about 3.5 billion years old. The mission is costing $2.7 billion and is thought well worth the price of satisfying the deep human urge to reach out and find life elsewhere in the universe.
I couldn’t help comparing that sum, though, with the current UK budget of £258 million for nature conservation and the protection of biodiversity. There is life on earth, right here and now, and it needs some help. Some of our own ancient inhabitants are in real trouble. Bees evolved sometime in the Cretaceous period, some 120 million years ago, at about the same time as flowers, with which they have ever since formed a mutual support system. The bees pollinated the flowers, which competed for their attention with the huge variety of different colours, shapes and fragrances they evolved to lure them in. In turn, the flowers offered the bees pollen and nectar and the bees themselves diversified to take advantage of this bounty. We come into this biological equation too, since we depend on crops the bees have fertilised – in fact it has been estimated that the value of pollination for human food is more than £110 billion a year.
But bees are declining fast. They have lost important habitats of flower-rich meadows and suffered terrible collateral damage from pesticides, herbicides and parasites. We’ve all read the headlines about this, but how much do we really know about them? Most people can recognise a bumble bee and a honey bee, but did you realise we have 24 different kinds of bumble bee in Britain and 270 other kinds of bee, 250 of which are called ‘solitary bees’ that don’t live in hives or big colonies. These have a huge range of life-styles, indicated by such intriguing names as miner, mason, leaf-cutter, wool-carder and sweat bees. Worldwide, there are 20,000 kinds of bees, more than all birds and mammals put together.
Well, you can see where my Easter parable is heading. Are we at risk of learning more about 3 billion-year old microbes on a dead and uninhabitable planet 140 million miles away than about the buzzing and blooming life that sustains our own live one and that lifts our hearts again every spring?

Village Voices Nature Note: Sounds of Summer
01 Sep 2020
I have a wonderful childhood memory of high summer – just lying in the long grass, looking up at the blue bowl of the sky and hearing the sounds of crickets and grasshoppers chirping away endlessly all around me. This came back to me the other day when I found a splendid Roesel’s bush cricket actually sitting on my back gate. The bush crickets are a special group, considerably larger than most grasshoppers, and make very loud and distinctive sounds. Whereas grasshoppers produce these by rubbing their wing-cases against their legs, bush crickets do it by rubbing their wings together. An expert can distinguish all their different ‘songs’ just as easily as different bird songs, though alas they are so high-pitched that once you’re over 50 you start losing them. I do remember the Roesel’s song, however: an extraordinary crackling like the sound of overhead electricity pylons. Naturalists have had to resort to equally bizarre similes to describe the other species in the stridulation section of this insect orchestra: the great green bush cricket ‘like the sound of crystal beads dropped in a stream down a crystal stair’; the cone-head ‘a quiet sewing-machine purr’; while the alarmingly-named wart-biter cricket produces a rapid burst of short clicks; and the oak bush cricket uses his long hindlegs to beat out a tap-dance ‘like the sound of soft rain’.
Grasshoppers have inspired some human music, too. Benjamin Britten composed Two Insect Pieces for piano and oboe, where the bounding gait of the grasshopper is contrasted with the angry buzzing of the wasp. And John Keats celebrated the cricket chorus in a lovely poem that begins, ‘The poetry of earth is never dead’, making the point that you could hear crickets through winter as well as summer. Or you could then, when the cricket on the hearth, immortalised in Charles Dickens Christmas Story, was a cheerful presence in many households. It is said that you can use the house cricket’s chirps as a thermometer. The formula for a centigrade reading is: count the number of chirps in 14 seconds, add 25, divide by three, then add four. So, if your cricket chirps 112 times a minute it should be about 20°C outside. Check it out though you may have to listen for your house cricket in a boiler room nowadays.
Crickets and grasshoppers are all members of the large family called the orthoptera (meaning ‘straight-winged’), which also includes the grasshoppers of folklore we now call locusts. Despite their destructive reputation, the Bible calls them one of the four ‘little things’ regarded as ‘exceeding wise’, along with ants, spiders and rabbits. ‘Why?’ is another story.

Darter

Lots of dragonflies on the wing this week. I've seen brown and migrant hawkers helicoptering along the dykes and today got a close veiw of a delicate common darter resting on a bramble leaf.
