Purple Emperor butterfly (Apatura iris) feasting on fresh dog turd
Such a beautiful creature with such un-photogenic habits! Infamously the Purple Emperor butterfly (Apatura iris) spurns the sweet nectar of wildflowers in favour of dog faeces amongst other delicacies.
Now mostly confined to the ancient deciduous woodlands of Surrey and Sussex in the UK, the Purple Emperor has a devoted following in the world of butterfly fans.
Normally it flies high in the woodland canopy and only occsionally will the male descend to the ground to replenish its liquids and salts in this peculiar fashion. On these rare occasions the Emperor’s acolytes fill their boots.
Here on Bookham Common in Surrey, within sight and sound of the M25 motorway, the lack of a long lens is no handicap when this butterfly is distracted by a fresh deposit:

The less exotically coloured female at least has more refined tastes, and generally remains high in the oak trees feeding on the sticky sweet honeydew secreted by aphids. She returns a little closer to earth only to lay her eggs in a suitable sallow tree nearby.

Such is the lure of the Purple Emperor that fanatics have been known to entice ‘His Majesty’ down from the trees with a number of foul smelling concoctions. In the absence of dung a rotting carcass may occasionally do the trick. This recently deceased rodent at a favourite butterfly haunt in the wood may have benefited from a coroner’s inquest:
If you’re looking for a photographic challenge then wildlife macro at night is guaranteed to keep you amused and frustrated in equal measure.
Glow worms (Lampyris noctiluca) come equipped with their own bioluminescent light source, and with a bit of research shouldn’t be too difficult to locate in the right environment. But in the dark simple tasks become considerably more complicated.
These ‘worms’ are in fact a beetle. On summer nights the flightless female glow worm climbs a grass stem,, or other vegetation, and emits a bright chemical light from her lower abdomen. This luminous display attracts the flighted male glow worm and mating begins, at which point the happy couple turn out the light and retire to bed together in the undergrowth.
In the UK glow worm numbers – or at least the number of people reporting them – have diminished over the years. Light pollution from sprawling urban areas may be one reason for this, as the female doesn’t like competition, and seeks out the darkest rural recesses in which to display to potential mates. The inexorable rise of the motorcar has also meant fewer people traversing the countyside on foot at night, and so less likelihood of happening across these creatures. Modern use of pesticides may also have played a part.
The wilds of South Dorset proved good hunting grounds for me last year and I was keen to have another crack at this subject in Surrey over the summer.
Initial research turned up not much however. Almost every contact I quizzed looked at me with bafflement and a little wonder when I enquired about glow worms in the county, as if they’d become semi-mythical beasts in this stretch of the London commuter belt. A bit of Googling turned up a handful of vague mentions and precious few images.
The excellent UK Glow Worm Survey website, run by the extremely dedicated Mr Robin Scagell, offered more precise records and this especially tantalising glimpse of days gone by:
Box Hill, nr. Burford Bridge, Whole slope of Hill covered with glow-worms, summer 1915
Promising, but a long shot more than 90 years later perhaps. Then a chance meeting with a twitcher confirmed glow worms sighted in a very specific area of the hillside in the 1980s and the balance of probabilities swung in favour of action!
From my vantage point atop the steep chalk slope of Box Hill the sun began to set impressively, and the exhausting vertical scramble required to get there faded into memory.
Tight security in preparation for the Olympic cycle race meant that the entire National Trust property was ringed with high steel barriers. A checkpoint restricted traffic up the narrow zig-zagging road to the top, and guards with walkie-talkies patrolled its length. The pedestrian gates thankfully remained open.

Bright lights from the dual-carriageway below continued to illuminate the entire downland slope after the sun had faded, which wasn’t promising. But in a deep, shady dip behind the ridge a twinkling greenish light in the grasses finally caught my eye.
In total 8 glowing females were located along a short stretch of chalk track.
The first young lady was tucked well back into the shrubbery and inaccessible to my lens. The second was more exposed, on leaf litter near to the ground. With a bit of tripod gymnastics and some macro slider extension action I edged within range.

In this shot the natural glow from the beetle was supplemented with indirect light from an LED torch off to one side. It’s a balancing act to expose the whole subject without drowning out the insect’s own subtle illumination.
The same creature on a long exposure without the artifical light source gives a quite different visual impression:

More typically glow worms can be found in thick grass, clinging to the stems a short way up, and rotating their bottoms skyward as this next one was:

Where the beetle is tightly surrounded by reflective surfaces the light she emits is magnified.
In all the above images the glow worm’s head is firmly concealed beneath her carapace, and this is usually the case I’ve found. But before I departed for the night another individual proved less coy.
Glow Worm Red Light: Glow worm under red filter LED
In these circumstances a bright white light can disturb the beetle, which then turns tail and vanishes, which is no good for observing behaviour. So I used a red filter, hoping she would be less sensitive to light in this part of the spectrum. It appeared to work and she continued to clean her antennae for some while:
I’m told there hasn’t been a short-eared owl seen in this part of Surrey for the last 30 years. I can’t be sure that this is true, but the presence of 3, 4 or possibly 5 individuals on the local water meadows this winter is highly unusual and they’ve become local celebrities. The human observers frequently outnumber the owls several-fold.

It’s been a bumper year for voles in the UK, and also lemmings in Scandinavia where our crop of over-wintering short-eared owls originate. Consequently the owl population seems to have exploded and many of them have flocked to these shores to escape the icy conditions back home.

Surrey Wildlife Trust graze one of the plots for conservation and the owls appear to like what they find in the grasses.

With any luck the shorties will be resident with us for the remainder of the winter.
The English oak (Quercus robur) provides wonderful habitat for numerous creatures, but in the (relatively mild) depths of a British winter, they keep a low profile. Wait an hour or so after dark however and the trunk of an unassuming oak tree suddenly becomes an insect super-highway.

A particularly interesting creature is the flightless female winter moth, which emerges from the ground and climbs the nearest trunk to liaise with the flighted male moth at altitude. She then lays her eggs high up in the canopy.

In a ‘good’ year hundreds of female winter moths may be seen to climb the trunk of one tree in a single night. This is not necessarily good news for the tree however, as the caterpillars rapidly denude the leaves after emerging in the spring.
Taking photos of small wild creatures in the dark presents a few challenges! To light these subjects I used an LED lamp attached to my tripod. This is a lot more predictable than using flash in inhospitable outdoor conditions, but does require a relatively long exposure time.
Many of these bugs will freeze in the bright white light required for conventional photography. This is not necessarily a bad thing for macro work, but it can alter their behaviour in an undesirable way. A young leopard slug was quickly in defensive posture for example, and remained so:

It’s also cold, dark and more than a little spooky in the woods after dusk in December, so requires several thermal layers and a degree of commitment!
I was delighted to be voted Winner in the Spring / Summer 2011 ‘Images of Durlston’ photo competition earlier this month, with this image of a juvenile peregrine patrolling the clifftops:

Durlston Country Park and Nature Reserve is located on the south coast of Dorset just outside Swanage.
I was fortunate enough to be a regular volunteer at Durlston for more than 2 years. This shot was taken on a brief return visit in July of this year, with a Canon EF 100-400mm lens and a bit of luck.
Two peregrines fledged in the area this year and could regularly be seen from the coast path over the summer – alternately terrorising the nesting seabirds on the cliffs below and testing their new wings in mock aerial combat with each other, and with their increasingly unamused parents.
A former boating lake beside the A3 dual-carriageway in Surrey around rush-hour is not the first place you’d go looking for hobbies in the UK. But a pair of these young raptors fledged in the area this summer on land managed by the Surrey Wildlife Trust.
I’ve had good views of hobbies in Dorset before as they pursue their favoured dragonfly food, and whilst it’s reasonably easy to capture them eating their prey mid-flight, snapping the fleeting moment in which they close in and grasp their nimble prey is another matter.
On this particular gloriously warm and sunny September afternoon I sat by the lake shore and waited as a pair of birds arrived from the neighbouring heathland and began one of many bombing runs up and down the lake in front of me.
A handful of shots managed to freeze this aerial ballet between predator and would-be prey for a moment:
When one of the hobbies paused from the fray in the branches of a pine overlooking the lake it was even joined by a sparrowhawk, which must have been studying its technique with some envy:
In the scorchingly hot, dry month of June 2011, Upton Heath near Poole in Dorset caught fire. I happened to be on the Arne peninsula at the time, and recorded this video footage from the opposite side of Poole Harbour:
Fanned by strong winds, the fire spread rapidly to become the largest heathland blaze in Dorset for decades.
Upton Heath was home to some of the UK’s rarest wild creatures, including the smooth snake, sand lizard and dartford warbler.
Over the following few days I documented the aftermath of the fire for the RSPB and Natural England, with permission of the Dorset Wildlife Trust’s team on-site:
