It has been a weird summer with quite a lot of rain and cool temperatures early on. Nature has had to use all its survival strategies to ensure the continuance of species.
Of all creatures on this planet (if you take viruses and bacteria out of the equation) on land, at least, Insects are the most adaptable; yet they are not invulnerable to the changes humankind is making to the land – in particular day-flying, scaly-winged insects,
Butterflies have earned themselves the unenviable role as an indicator species. In the mid 1970’s a member of the family known as ‘blue butterflies’, the large blue, became extinct in this country because of aggressive land management, habitat destruction and a misguided attempt at conservation by people paid by the government to manage the habitat on which the last remnant of the large blue depended. On continental Europe, particularly France, the large blue thrived, though it too is in decline partly due to the subsidy-rich agriculture promoted by the EU. Until the turn of the millennia there was still a great deal of the rough farmland on which this insect’s larval food plant, wild thyme, grew in profusion and on which a particular species of meadow ant also thrived; this meadow ant being a vital link in the development of the large blue caterpillar.
The post office produced a postage stamp depicting British butterflies, including the large blue, painted by a close friend and fellow naturalist, the renowned wildlife artist, the late Gordon Beningfield. Almost single-handed Gordon promoted the value of butterflies as indicators of the health of the countryside and campaigned to found the organization “Butterfly Conservation”, a charity he supported until his untimely death from cancer in 1998 aged 61yers. I had the good fortune to be a close friend, near neighbour and fellow conservationist for more than thirty years and my family and I still have a long-standing friendship with his family.
I have been fascinated by butterflies and moths since childhood and always look forward to the first butterflies of summer, the holly blue and the brimstone, and in high summer I love the sight of Buddleia with its blue or white nectar-rich florets a magnet for butterflies such as painted ladies that have migrated across the Channel on southerly winds from as far afield as North Africa.

Other butterflies that migrate from Europe include the beautiful red admiral and the clouded yellow, the latter not a regular visitor to buddleia, though I have seen them in Dorset taking advantage of the nectar-rich flowers. Other members of the same family as the red admiral are the peacock and the small tortoiseshell. Both lay their eggs on the leaves of nettles as will the comma butterfly – so called because it has a white mark just like a printed comma on its under wing.
Our British population continues to decline because of aggressive agriculture, sadly the “guardians of the countryside” as famers like to be known still plough up wild flower meadows and spray potent agrochemicals that kill the food plants of the butterflies as well as the insects themselves. If you wish to see butterflies in any profusion, other than whites, one has to make a journey to a nature reserve.
Perhaps sanity will begin to drive conservation now that soon we will be moving away from the pervasive influence of EU supported agriculture; although I am not sure of the outcome as government are saying that the British taxpayer will be picking up the tab. However, I am hopeful that there will be no repeat of the demise of insects as there was with the large blue and our children’s children will have the delight of gardens full of summer butterflies and a countryside rich in wild flowers.

To: My very good friend Dennis. There’s not enough space to congratulate you on your wonderful blog. Very professional and is far better than any other I’ve seen. Photo’s of high quality and words of wisdom. For me a good tonic as it reminds me of those wonderful days/months we worked together on Natures Way for Anglia TV . I’ve worked on many film productions as cinematographer and without a doubt I enjoyed and respected every moment we worked together as a team. Your knowledge on so many subjects made each program special hence a big hit for Anglia TV. Well done Dennis and goodness would love to repeat those days filming with you knowing the end product would be successful for viewers to enjoy nature without hearing endless waffle as a time filler.. Thank thoughts and of course to lovely Ann…………………..
