As a young lad, I used to read the books of the naturalist and field sportsman Denys Watkins-Pitchford other wise known as 'BB'. He was a great writer and illustrator who's evocative descriptions of warm summer days watching butterflies or wildfowling on ice and snow bound salt marshes would hold me captivated.
In particular I loved to see his black and white lino cuts and ink drawings. He was agreat inspiration. Nowadays his field sports interests might be a little bit frowned upon but he was a man of his era.
I can remember reading about his love of Apatura iris, the Purple Emperor butterfly that was an elusive and declining insect of the forests of the midlands and south of England. BB used to look for the eggs on sallows and take them to rear into adults away from predators to release the next summer. He was concerned that they may disappear altogether as a result of foresters spraying pesticides on oak trees to rid the woods of tortrix moths.
Fortunately, this practice seems to have stopped and iris numbers are on the increase. Or maybe it is due to some warmer summers in recent years in the areas they are found?
Last summer was a good one in the East Midlands with many Purple Emperors on the wing in the Rockingham Forest woodlands of East Northants. It was then that I decided we must have a trip down to have a meeting with the creature affectionately known to his fans as 'His Imperial Majesty'.
Fast forward to the heatwave of summer 2018. As the UK basked in 30 degrees temps for weeks on end, the Emperor was on the wing earlier than usual and in bigger numbers. At the Knepp Wildlands project in West Sussex, for example, Matthew Oates counted over 300 on the wing in late June, making them more numerous than Meadow Brown! Knepp is a bit far to go over two days for us (and a bit expensive to get access) so last weekend John and myself visited the old stomping grounds of BB himself - Fermyn Woods in Northamptonshire.
We left sunny Northumberland at 4am and were onsite by 8.30am. Only one car was parked and its occupants had already left for their walk. As we entered the woods, I was a bit disappointed to see that the forestry people had annihilated the trackside scrub including all of the sallows favoured for breeding by the Emperors. What would BB have thought?
Onwards and upwards though, and a movement half way up and oak trunk attracted my attention. It was a worn old female Purple Emperor! First butterfly of the day too. This is a doddle, we thought.

Only 50 mtrs from the parking area, a young lady said she had a male up in the taller trees. Another visitor has sprayed a little attractant ( vile fish oil) onto the track to no avail. She soon left, and John and me stood, gazing back up the ride hoping for a large butterfly to appear. No joy, so we turned to head off and there, on the path, 3 feet away, was His Majesty spread eagled in the dappled shade. I pushed John to one side and I the other to prevent him being trodden on and thought that was our chance gone, he was bound to flush back to the high oaks. But no, he sat a while then flew a few feet and landed again and sat there for the next hour enjoying sucking his yellow proboscis on the hardcore path.

What a great experience!
We were staying in The Woolpack Inn not far away overnight so I'll do another post about the next day soon....its mostly odonata...
