Thank you Mark and Bill. I have never knowingly seen a Peacock larva before so I am pleased that I was able to help them on their way. I actually just moved them off the middle of the path to the relative safety of the verge Vince but thank you for the information. It may well be useful in the future as I think it would be fascinating to rear some butterflies and watch their development but right now I probably have enough critters to care for.
Thank you Wurzel. You should know that I have friends who are fans of yours and read your diary even tho' they are not interested in butterflies - yet!
Today I arrived at the Straits around midday and I had only been at the 'hotspot' for a couple of minutes when Neil arrived on his bike. Just as he dismounted I spotted the first Purple Emperor of the day. He did quite a few circuits of the area coming down lower each time before landing on the of back Neil's trousers. I am willing to bet that Neil has never had his backside photographed by so many folk in such a short space of time
I don't think I have ever noticed quite how blue the antennae are. The PE finally had his fill of whatever was on Neil's trousers and after circling the tower several times decided it preferred the resin to be found there. I continued to get some unusual, albeit distant, shots of the butterfly:
'Under lock and key' is the best slogan I can think of, but if you can do better? ...........
Casting a wonderful shadow.
The butterfly repeatedly took to the air only to return to the upper levels of the watch tower. Undeterred, Neil decided that a mere watch tower was not going to get in the way of him getting a close-up shot:
Unfortunately, the PE was disturbed by the movement of the ladder but obligingly returned to Neil's boot (just about visible on the left one) so he tried his best to descend slowly in an attempt to bring it down to the rest of us:
By now, something of a party atmosphere had developed and a group of photographers were busy in one corner recording a veritable butterfly fest, the likes of which has probably never been seen before

. It was difficult to know what to photograph first
At one point there were 6 butterflies of various species on a single leaf but I, personally, was only able to record 5 - 2 SWF, 2 WA and a Comma.
.... and why was all this happening??? Well, here's the clue:
