Wasp Spider by Michael Blencowe for Sussex Wildlife Trust

I never thought I’d say this, but I’ve fallen in love with a spider. And coming from a lifelong arachnophobe that’s quite a claim. Whereas every other spider species sends me screaming in utter terror, the Wasp Spider has melted my heart. They are gorgeous. I met one on the South Downs last weekend and, hypnotised by her beauty, I spent hours with her; lying in the grass, staring lovingly into her eight eyes.

Wasp Spiders’ rotund abdomens are delicately patterned with exotic black, yellow and white stripes. Every Wasp Spider looks subtly different – as if each has been individually hand-painted. Their eight legs wear stripy black and white stockings – the sort favoured by the Wicked Witch of the East. This stripy, waspish appearance has given the spider its name and is used as a defence mechanism to ward off predators who equate this colouration with being stung.

They’re a relatively new resident in England. The first British Wasp Spider was found near Rye in 1922. Since then they have slowly spread across Sussex and you can find them in any areas of grassland. Here inside their long grass lair, they weave their silky circular webs which – like all spider webs – are a masterpiece of arachnoid architecture. As if proud of her accomplishment the Wasp Spider autographs her web with a unique silken squiggle. The actual purpose of this thick zigzag flourish (the ‘stabilimentum’) is a mystery; although some believe it reflects UV light, luring in pollinating insects who mistake the web for a flower.

Male Wasp Spiders don’t have it easy. Physically they lack any snazzy patterning and at 5mm are a third of the size of their hulking female counterparts. And when it comes to spider sex, she dominates the male too. During mating she turns her lover into lunch. So, as the female lies enticingly in her web, the male approaches her with understandable trepidation. It’s all about timing. After she slips out of her old exoskeleton and into something more comfortable, her fresh body is temporarily soft – and so are her jaws. This is her Achilles heel, an opportunity for the male to jump in, do his business and get out before being eaten. This sort of pressure would affect any fellas’ performance, but the male Wasp Spider has a trick up his eight sleeves: he can detach his sexual organs, leave them inside the female and scarper.

I always assumed that jettisoning his genitalia allowed the spider to survive, but almost every mating session ends in death for the male. Scientists have found that after this self-imposed castration, the spider’s sexual organs keep on fertilising the female and block other males’ attempts at mating. The spider sacrifices his own life to save his member and ensure he becomes a father. Wow, what a way to go.

Horse Chestnut by Michael Blencowe for Sussex Wildlife Trust

Far, far away in the south-east corner of Europe, the Balkan Mountains tower over the landscape. Their valleys were once home to the fearsome Thracian tribes, who made empires tremble when they rode screaming into battle on their wild horses. But even more ancient battles were being fought deep in these majestic mountains.

Here in the Balkans, there grew a strange and mighty tree. Its huge seeds were encased in spiky armour and its leaves were like giant hands which cast shade all around. But this tree had been cursed. Each year a plague of tiny moths would attack the tree, their caterpillars would burrow inside every leaf. Green leaves turned to brown, leaving the tree apparently lifeless and defeated. Yet each year the tree would return with renewed green vigour, and each year the moths would attack with the same resolve. And so, for centuries the tree and the moth remained trapped in the Balkan Mountains, locked in their epic, age-old battle.

Then one day men came from the west, discovered this magnificent tree, gathered its seeds and planted them in their world. And so it was that the branches and the empire of the Horse Chestnut spread across Europe’s parks and gardens. People admired it and reclined in the shade of its broad palmate leaves. Schoolboys used its seeds to fight their own playground battles. The conker tree had conquered the continent. Here in this new world the curse of the moth had been lifted and the Horse Chestnut flourished. Meanwhile, the tree’s nemesis, not a particularly strong flyer, remained imprisoned in the remote valleys of the Balkan Mountains for centuries, more myth than moth. Then, one day, the modern world arrived. Construction workers building roads through the mountains were unwittingly building the perfect means for the moth to escape and spread. Now all it needed was a lift. So, the moth stuck out its six thumbs and hitched a ride.

Incredibly, the moth, just 5mm long, was able to disperse by grabbing on to passing vehicles. And so, like the ferocious Thracian tribes, the moth rode into battle. Screaming along highways, motorways, and autobahns on Volvos, Citroens, Fiats and Fords. The ancient battle spilled out from the Balkans as the moth was chauffeur driven to every Horse Chestnut tree in Europe. The Horse Chestnut Leaf Miner moth was first discovered, identified and named in Greece in 1984. Twenty years later, in 2004, an innocent motorist pulled off the A27 in to the University of Sussex car park, unaware they had brought a sinister stowaway into Sussex. Since then, every Horse Chestnut in Sussex has been moth-eaten. Look to the leaves and you’ll see the great Balkan battle raging right on your doorstep.

Purple Emperor by Michael Blencowe for Sussex Wildlife Trust

In any book on British butterflies, you’ll find our 58 species segregated into social ranks: the common browns, the blue-collar blues, the working-class whites. But turn the page, past the lepidopteral lower-classes, and you’ll find a butterfly so unique, so magnificently majestic, so breathtakingly beautiful that for centuries British naturalists have bowed before it. Draped in resplendent robes of iridescent amethyst, obsidian, and ermine the Purple Emperor has to be one of the most impressive animals on our island. In July the purple reign begins.

Aside from an alluring appearance, Emperors also possess that combination of rarity and elusiveness which has elevated them into an almost mythological figure: a butterfly bigfoot. How a large, shiny, purple butterfly manages to exist undetected in our countryside is down to an arboreal existence. Purple Emperors spend almost all their time on lofty thrones high above our woodlands. If we’re lucky we may glimpse the glide of a wide-winged silhouette as we stare sore-necked and squinting at the Sycamore skyline. Up there, in their canopy kingdom, Emperors compete in a power struggle for territory and males gather for summer tree-top tournaments. Their wings flash as they clash in acrobatic aerial jousting, and they spar and spiral high into the Sussex skies. The Emperor’s ferocity and fearlessness in the defence of his realm are famous. Butterflies, bumblebees and other insects get a battering if they trespass and, incredibly, bemused birds (including Sparrowhawks, woodpeckers, gulls and herons) also receive a warning wing-slap.

Emperors don’t lower themselves to feast on flowers like other butterfly riffraff. The Emperor sups sugars by quaffing only the finest honeydew distilled by aphids in the treetops. Yet, in complete contrast to its aristocratic high life, the Emperor has some dirty habits which drag him down to the filthy forest floor. To get his majesty’s mojo working he requires a mid-morning meal of minerals, which he obtains by probing his proboscis into the most disgusting muck he can find. Dog poo, used nappies, dead animals, sweaty feet – nothing is too repugnant. It’s like finding the King rummaging through the bins at the back of Tesco.

The female Empress does not have the shining sheen or horrid habits of the Emperor but she too descends to lower levels searching shady Sallows for a place to lay her eggs. Camouflaged caterpillars munch from August to June before giving rise to another distinguished (but disgusting) dynasty.

Recently, the Emperor has extended his empire eastwards. Once a butterfly of north-west Sussex it can now be found all across the north of the county and has been reported around Uckfield – there have even been rumoured sightings in the very heart of Brighton – so keep your eyes to the skies.

Swifts by Michael Blencowe

Swifts by Michael Blencowe for Sussex Wildlife Trust

These are uncertain times. Who knows where this planet is heading? But since the start of May I’ve been looking to the sky for a sign of reassurance: the return of the Sussex Swifts from Africa. Ted Hughes expressed it perfectly: “They’ve made it again / Which means the globe’s still working, the Creation’s / Still waking refreshed, our summer’s / Still all to come.”

Swifts may not look like much – they’re basically two wings and a mouth – but it’s hard to explain their abilities without making them sound supernatural. Swifts are all about flying. They feed, scream, and mate in the air and bathe in the rainclouds. At night they switch off half their brain, switch on cruise control and fall asleep amongst the stars. If they had their way they would never come down. But there’s one little flaw in their plan: eggs don’t float. So, for just a few weeks of the year, they begrudgingly swap the open skies for a cramped nest under the eaves where they raise their young. The problem is in recent years most of these little gaps have been lost to renovations and modern architecture. The destruction of their homes is one of the reasons why Swift numbers have fallen. They are refugees on the wind.

They cruised into Sussex in May after a non-stop, long-haul flight from Africa; not that this trip bothered them. Swifts are all about flying. For me, the Swift is the only bird that takes pure, unadulterated pleasure in flying. Other birds fly out of necessity, but Swifts seem to fly for the joy of it, screaming with delight at the top of their little Swift lungs, a shrill cry that is forever associated with English summers.

By the time you read this, a new generation of Sussex Swifts, born in a roof cavity, have crawled to the nest entrance, and bravely launched themselves on their first flights. And what a first flight – they may not land again for two or three years! For these ‘teenage’ Swifts, the skies of Europe and Africa will be their playground. Nothing will tame them. Well, not until they meet a partner and decide to settle down in a roof of their own somewhere. But don’t let this comfortable image of domestic bliss fool you – there’s no taming these Wild Ones.
