Thank you Wurzel, Dave, David, Pauline and Bill for the great comments

. Apologies for the delayed response, I just returned late yesterday from a few days away and now have some catching up to do, both with my own PD and everyone else's.
To be honest I didn’t notice the black spotting on the Common Blue at the time (should have gone to Specsavers…

) but now it has been mentioned I realise I have not seen one like it before either.
Tuesday 28th July – A few days up north part 1.
On Monday 27th July we set off up the M6 for a few days in the Arnside and Silverdale area, staying at a B&B right next to Gait Barrows National Nature Reserve. With rain forecast for most places on Monday we decided to take our time and didn’t set off until mid-day. The run up the motorway was mainly under a heavy grey overcast and we didn’t actually see any of the wet stuff until we had passed Lancaster but then it rained constantly for the rest of the afternoon. We headed straight into Arnside and had a coffee before carrying on and checking into our B&B and by the time we were settled in and freshened up we were ready to pop out for a meal.
With the weather for Tuesday looking like it was going to be more cloud and rain we decided to go to RSPB Leighton Moss which was just a minute or two drive around the corner from our B&B. We have been here before whilst up in the area and Jane likes it because there are good paths to some of the hides which she can manage with her walking frame. On the way in through the visitor centre one of the chaps behind the desk told us that there were two pairs of Marsh Harriers with juveniles that had been out most days when it stopped raining and also to look out for a Great White Egret that had been hanging around for a while.
After wandering along to the Tim Jackson and Grisedale hides and seeing a couple of Herons and some Lapwings out in the light drizzle we wandered back to the café at the visitor centre for a coffee. Coming back out onto the reserve again the rain had stopped so Jane went to Lillians Hide, which is the closest to the visitor centre whilst I went for a look from the new Skytower viewpoint which is close by.

I had just got to the top of the tower when I saw a large white bird glide in and land on the far side of the pool to the front of Lillains Hide, albeit on the far side of a small Island which obscured the bird from the hide. From its size and exotic appearance, this was obviously the Great White Egret that we had been told about. I took a few long distance photos and went down to meet Jane in the hide and to see if it would come out from behind the island.

After a minute or two it came into view and spent a good twenty minutes or so wading up and down in a stately manner as if it knew it was the best looking bird in the pool.

At one point the Great white Egret took off and looked to be leaving but only went about ten yards before coming back down.

- Lift off...but not for far.
After another ten minutes it took off again and this time flew off across the reed beds and out of sight.

- Now it is on its way...
Shortly afterward, a Little Egret appeared on the far side of the pool, looking a bit shy as if it didn’t want to show up whilst its bigger cousin was stealing the limelight.

- Has it gone?
We then wandered back down to the Tim Jackson Hide where there were a pair each of mute Swans and Herons just yards in front of the hide.

One of the Marsh Harriers then flew across in front of the hide and was joined by a second. They both flew about a bit providing distant but good views before flying off back to the north across the reserve.

After spending a few hours at Leighton Moss Jane was now tired so later in the afternoon, whilst she was having a rest back at the B&B, I went for an hour up on Arnside Knott. There was still a lot of heavy cloud and occasional light drizzle with the temperature display in the car showing 15 degrees at most.

- Grey skies over Arnside.
Despite the dull and damp condition it was just about warm enough for Meadow Browns and Ringlets to be flying in good numbers plus a fair number of Gatekeepers. I have noticed before that a lot of the male Gatekeepers here are on the small side and the individual below was quite a dinky little chap.

At one point a bit of movement on the ground alerted me to a Common Lizard trying to warm itself up on a bit of wet wood.

Then, in one of the glades above the scree slopes I spotted a much darker, almost black butterfly lazily flapping across a clump of ferns. It landed on a fern frond and a closer look confirmed it to be a male Scotch Argus.

All in all a good day despite the cloud and occasional rain which actually turned out to be lighter and less frequent than forecast. Not only that but I had seen my main target of Scotch Argus, just the one so far but well chuffed with that given the dull and damp conditions…and the forecast was looking a bit better for the next couple of days.
Bye for now,
Neil
