Curiously Finemere Wood in Bucks was deserted of people this afternoon but fortunately there was plenty of Emperor action on offer. This fine fella landed on my jeans as soon as I entered the wood. I transferred him to my finger where he stayed licking salts from my hand for the next 50 minutes. I did a tour of the main ride up to the turning circle and back with him in my company.
The light was perfect to get a good look at him excreting fluids onto my finger and sucking them back up presumably extracting the salts from my fingers.
There were several other males actively searching the Sallows along the main ride looking for females. I think Dennis is correct, we are close to peak in the Bucks woods.
