Yes, a shepherd in London. Mid-March is lambing time, and she was out with her Land-Rover on the wide grassy banks of the reservoirs at Wraysbury, just beyond the end of the runways at Heathrow, checking that the new lambs were healthy. The ewe looks as though she’d like a rest, unsurprisingly. The grassy banks are quite steep, and mowing them would be costly and dangerous; how enlightened of Thames Water to use sheep instead. Genuinely “green”.
Also on the walk, several Brimstone butterflies, and a couple of Peacock butterflies (presumably overwintered in a hollow tree or some such place). Near the sheep were two Buzzards and a Red Kite, on the lookout for some carrion, I won’t mention what they were hoping to find. Also about was an early Chiffchaff singing its simple song (its name, over and over), a Cetti’s Warbler, and a Song Thrush. And a flock of Goldfinches finishing up the last of last year’s seeds in a big patch of thistles, burdocks, and teasels.
Ringlet, a handsome species we’ve hardly seen here, increasingA Peacock butterfly on Buddleia: once a common sight in every suburban garden, now a special treat. We used to call the Buddleia the “butterfly bush”; it would be covered in Nymphalids – Peacock, Red Admiral, Small Tortoiseshell, Painted Lady, sometimes dozens at once.Red Admiral sunning on Birch by the small meadowDefinitely not a butterfly: a newly-emerged Southern Hawker dragonfly stretching its wings just above the main pond amongst the Fool’s Water-cress
Water-Plantain beside the boardwalk: the water table is really low for this early in the summer. Netty failed to find any new-season toadlets around the pond where she’d expect them to be. The leaves are slightly heart-shaped, but nowhere near as arrowhead-like as its cousin the Arrowhead.
I’d hardly stepped onto the path before a pair of Peacock butterflies spiralled up in a territorial dispute – the little meadow was evidently prime habitat, and the males were fully charged up on this beautiful spring day.
Small Tortoiseshell on Dandelion
A bit further along, a Small Tortoiseshell was visiting some of the many Dandelions by the path. It’s certainly my first this year; and I can’t recall seeing one here at Wraysbury before. It was once a common butterfly but nowadays unkempt beds of Nettles are rare enough, and like all our showier butterflies, they’ve suffered from the changes to the countryside, including insecticide sprays.
Male Orange-Tip
The next delight was the first Orange-Tip of the year. It’s a “White” butterfly but with beautiful coloration above and below: the underwing is remarkably well camouflaged.
In a woodland glade, two Commas tussled for the best display position.
Alder-Fly
And near one of the lakes, an Alder-Fly clambered along a twig. The larvae are aquatic; on a good day in early summer, the air can be full of adult Alder-Flies.
Birdsong was pretty much continuous, with Blackcaps, Chiffchaffs, Great Tits, Song Thrushes, Blackbirds, Green Woodpeckers, a Cetti’s Warbler and I think a Sedge Warbler too all contributing their songs. A Heron gave a harsh croak and some ungainly squawks. A Parakeet shrieked overhead. A Kestrel hunted silently. Spring has sprung in Wraysbury.
We had a lovely day down the reserve in the warm sunshine with a gentle breeze. We dug out an unwanted post with extreme use of pickaxe, crowbar and shovel, and thus refreshed did the butterfly transect. It found a Red Admiral, some Speckled Woods, wonder of wonders a Small Skipper (the second Skipper species this week), a Meadow Brown (not common here), and a Green-Veined White. Not a bad haul. And a lot of Peacock caterpillars, if those count!

After all the rainy weather (I even found a large toadstool – in June: The Blusher, Amanita rubescens), today was suddenly hot, at least it seemed so while digging brambles out of the ramp meadow, raking up the scythed Cow Parsley in the full sun, pitchforking it into a barrow and carting it off to a deadhedge. It was a satisfying conservation job, one of those where you can see what you have done, and it looks a lot better after than before. The area is supposed to be a meadow; we successfully suppressed the overgrowth of brambles two years ago, leading to a burst of rather nice Garlic Mustard and its attendant Orange Tip butterflies last year: and a second wave of Cow Parsley that must have seeded itself really well, because it suddenly covered the area this year. Now that it’s all cut, we may hope that grasses and smaller herbs may get going: some Ground Elder at least has begun the process.
In the pond and on the vegetation for a way around it, including atop the hump, Large Red Damselflies are soaking up the sunshine, and flying in cop, egglaying – the females dip the rear half of their very long abdomens in the water to reach an aquatic plant such as Myriophyllum on which they place the eggs.
The butterfly transect was again quiet, but graced by the first Cinnabar Moth of the year: there is a fair bit of Ragwort coming up, and this adult must be newly hatched out of a pupa, presumably at ground level or below as the plants are annual.
Sure enough, after I had finished the transect, the first Holly Blue butterfly of the year, beautifully fresh and new, skipped its bright quick flight just in front of the hut.
I had a go at the ‘regular’ butterfly transect down at the reserve. It was warm and humid but overcast and it didn’t look promising. A large willow covered in Gypsy Moth caterpillars had been loosened by all the rain, and had fallen across the path. I lopped off the crown branches and carted them down to a dead hedge to fill in a gap someone had been climbing through.
The sun peeped out and the cloud cover reduced to maybe 60%, making it warm and pleasant. A single Small White appeared over the ramp and made it onto the transect. I wandered around the reserve, but there was nothing until I found a solitary Speckled Wood in the large meadow.
However, there was plenty to notice all around. The building site looks a lot better now the ‘Costa Concordia’ white horizontal balcony cladding on ‘Chiswick Point’ (well, it’s in Acton Green and on Bollo Lane, but I guess Bollo Block didn’t quite have the same cachet) has been completed: it will be nice when the noise of cranes and drilling stops.
Handsome iridescent green male Oedemera nobilis on Catsear
Many ichneumon flies were out on the Hogweed, some mating; almost every Catsear flowerhead had one or two handsomely iridescent green Oedemera nobilis, the “thick-kneed flower beetle” – only the males have the swollen hind femurs, but both sexes have a gap between the slender wing-cases. The males were of noticeably varying sizes, presumably the large ones having the best chances of mating.

Laburnum leaf beetle larva doing an impressive amount of leaf damage
The Laburnum by the main path is being eaten full of holes, probably a good thing for a non-native shrub in the reserve, by spotted and striped larvae of the Laburnum Leaf Beetle. Never seen it before.
Mating Rose Sawflies
The wild rose in the car park hedge was host to a mating pair of Rose Sawfly, a serious pest for gardeners but an attractive insect with a bright yellow abdomen.
Large Red Damselflies in cop over a lot of healthy Starwort in the pond
As if all these treats weren’t enough, there were Large Red Damselflies mating and egg-laying on the pond, Common Blue Damselflies, lots of Hoverflies, Click Beetles (seemingly Athous haemorrhoidalis), large brown frog tadpoles and small black toadpoles, singing Blackcaps, a Song Thrush, a Jay, and plenty more. Maybe it’s not just Bugs Day on Saturday, but Bugs Week.
A high pressure zone is bringing bright and mainly sunny weather to Britain, but as it’s not overhead it is also bringing quite a cold breeze. Down at Wraysbury Lakes, all the winter ducks have left, with just Tufted, Mallard and a pair of Gadwall remaining. Two Great Crested Grebes wandered around each other, not quite getting into a courtship dance.
Things were more exciting on the birdsong front. Blackcaps and Chiffchaffs sang sweetly all over. A Cetti’s sang very loud, very close by the lakeside as always, first in front … I stalked up very quietly … and then behind me. Invisible, the skulker. In the thicker scrub, several Whitethroats sang their scratchy short song, the first this year; and at least three Willow Warblers sang their descending scales, also the first of the year. And, briefly, one Garden Warbler gave me a burst of his even, musical tunefulness. There’s often a Sedge Warbler near the river but not apparently today. More song came from the Robins, a Song Thrush, and a Chaffinch or two.
Overhead, a Grey Heron circled upwards towards a Boeing 747-400 and did its best to resemble a soaring stork or crane, quite impressive really with broad, downcurved wings rather like one of those air-filled kites made only of light cloth.
St George’s Mushroom
A small patch of St George’s Mushrooms nestled among the Potentilla leaves by the path; it’s about the only edible mushroom at this time of year, but I don’t pick them, both for conservation reasons and because I’m not keen on their rather mealy taste.
The first Speckled Wood butterflies of the year are in evidence; they are fiercely territorial already, chasing off numerous Peacock butterflies. A few Green-Veined Whites settled, frail and shy, on the thicker herbs.
Ground Ivy
Great patches, almost carpets of Ground Ivy, which sounds a lowly herb, but looks glorious among the low-cropped grass, shining in the sunshine. It’s in the Labiate or Mint family, and has pretty rather short toothed leaves, purple-tinged, with attractive blue lipped flowers that are really quite orchid-like if you ignore their long tubes.
The English seem unemotional … except for their passion for nature
