Today, a windless, sweltering day, of the sort you remember from childhood summers: white clouds adrift in azure overhead, the whirr of grasshoppers, gorse pods popping, I set out on an insect safari through the Reserve, to see what I can find in a leisurely hour, walking and stopping for photographs. My sightiongs follow the contours of meadow and woodland, with the greatest concentration of species, as always, in the open, sunny grassland of the Bog Pond.
Where insect numbers are highest there will be the greatest choice of food for predators, so these numbers matter for us and the national statistics, which show a widespread, dramatic decline in insect populations, carry grave consequences for British wildlife as a whole. After all, though it is gratifying for us to help garden
birds through the winter on offerings of nigella seeds and dried meal worms from China, we cannot pretend that this is truly a sustainable solution. We are told that cuckoos are dying out for lack of moths to eat. How many of us know which plants are good for moths? I admit to real ignorance here, hoping that the big oak trees, the birches, willows and poplars at Stoneywish give enough scope for a range of species, but these invisible lacunae in the food web, may prove to be just as critical as the more recognised problems of pollution or predator imbalance.
Butterfly numbers for us seem to be down on last year. Perhaps the cold early spring affected them, but I find gatekeepers, common blues, the last of the skippers and meadow browns in the long 
grass, where over 20 species of wild flowers are immediately visible. Red admirals and commas are beginning to appear in the apple orchard, while speckled wood have been abundant, under the trees, since March. Early dragonflies are about too. And the flowers with far and away the most insect guests? Apart from the herbs in the herb garden, they are dreaded hogweed, thistle, blackberry, 
teasel and the greeny-white, waxy stars of white bryony, all with clouds of eager hover flies! Gold finches are busy already amongst the thistledown.
Perhaps a few stinging nettles, as a token gesture to conservation, are just not enough. We need to recognise that all these plants deserve a place near us if we want birds in our world. The goldfinches 
will move on to teasel seeds as they ripen in turn. Who will eat the great biscuit-like fruit of the hogweed? Or the poison-bright berries of the bryony and cuckoo pint, which bejewel the woodland floor?
Seeing nature whole, brings such staggering rewards. And you don't need infra-red equipment or a team of photographers from the BBC. It is cheaper and much more fun than weedkiller. We just need to slow down enough to look. Our children have everything to teach us here. We devise captivating entertainments for them, but they can access levels of pleasure to which, as adults, we have grown all but blind.
At the end of my safari I followed a family along a path to the Play Area. Two little boys, four or five years old, were trailing behind their mothers, recalling the highlights of their trip last summer. Ice cream? Swings? Friendly pigs? Not a mention! This is what I heard instead: "Yeah, this is the place with the Doctor Who plants.
I remember." "Yeah, the Dr. Who plants." Do they mean the giant himalayan balsam, which can catapult its seeds 6 feet when the pods explode? Another weed loathed by all, though punch-drunk bumble-bees think they have found paradise when they reach the blossoms. "Yeah, this is where the grasshoppers are!" "Yeah! The grasshoppers!!! .." Ah, those summer days of childhood ... Forget the latest stress-busting courses. All you need to do is step out of time and get down on your hands and knees!
