Thank you Goldie. I'll keep my fingers crossed for you
I know my observation skills are not as strong as they should be and I WAS curious about the colour of that Chalkhill Blue. I decided to return to the site to have a better look at him and hopefully get some better shots as, for once, there was no wind. I assumed he would be easy to find, not having flown far since yesterday evening given the cool temperatures. How wrong can you be!

As I drove past Butser Hill I could see it was shrouded in mist and although it wasn’t raining I needed to put the windscreen wipers on to clear the droplets of moisture collecting on them.
By the time I got to Oxenbourne, a mere 10 mins drive away, the mist had become drizzle and the wind had whipped up from no-where! Great!!

Shorts and trainers were not really up to the job so I started off by treading carefully. It was prudent to do this in any event as dozens of butterflies were hunkered down in the grass for some small protection against the weather, including the Chalkhills, which I had expected to find easily, roosting on stems of grass. I realised it might be a little more difficult than I’d anticipated.
One of the first butterflies I encountered was a worn, female, Marbled White, covered in raindrops followed by a Small Skipper tucked away as safely as he could be......
....... but I was on a mission, and proceeded to carefully check every Chalkhill I could find, scrutinising them for minor differences. Many of the male Chalkhills were very pale but I searched hard for specimens that had a dark colouration, similar to the butterfly from yesterday. The darkest ones I could find were these:
However, none were the same shade or tone of brown as the one from yesterday and their dark colouring did not extend all the way down the hind wing, tending to fade out to be replaced with blue. I found a couple of females and their colouring, although a bit deeper, was very similar to that on the hind wing of yesterdays butterfly.
I continued to search for him but couldn’t resist a few snaps as I did so including this rather attractive moth:
Suddenly, there he was on the grass in front of me – there was no mistaking him because of the damaged wing:
Frustratingly, the wind was now even stronger than yesterday but at least today I had a little more time. The shots are not great but they will do for illustrative purposes. The weather was deterring butterflies from flying so to enable an easier comparison between yesterdays butterfly and one of the darker specimens from today, I carefully placed the 2 of them on the same stem:
I appreciate that aberrations in Chalkhills are very common and variations even more so but I was happy to have confirmed to myself that it wasn’t just the spots that were different but also the colouration to quite an extent, although the degree of difference doesn’t show up as much in the photos as I would have liked

.
On returning home and looking at my photos of my specimen from yesterday I noticed this (what was that about my lack of observation skills?

) Does anyone have any idea what is going on here? I assumed this was meconium but this butterfly was flying round yesterday and I thought that was something that was emitted shortly after emergence? I’m definitely not going back again to check!!!!
