Monday 29th August 2011 – West Williamston (Pembrokeshire)
I’d wanted to return to West Williamston since last year’s trip (also on the August Bank Holiday) but the weather hadn’t been that reliable. I’d decided that with a good forecast this Monday might provide the best time to go – however, we were already a little travel-weary from coming back from Kent the night before. Nikki who does much of the co-ordinating and managing of the reserve had organised a Brown Hairstreak count from 11-12 so I knew the reserve might be a bit more busy than normal.
After a good drive across to west Wales we arrived to clear sunshine at the reserve just after 9pm. However, my confidence in the forecast turned out to be a bit ill-founded as some cloud came over and it was soon clear that shorts and a t-shirt weren’t the best thing to wear this morning! We did an early morning walk at the estuary’s edge, being careful not to slip on the kelp from the morning’s tide. We got back to the car for the early morning organisation from Nikki – there were probably about 16 enthusiasts and local wardens willing to help with the count - and so Karen and I spent the ‘spotting hour’ in what she calls ‘the middle field’. However, the sun kept on coming in and going away again and I knew this was ‘borderline’ conditions (again) for the Hairstreaks. We had 1 possible sighting at the top of an Ash, but otherwise there were only Speckled Woods, Large and Green-Veined Whites, Small Coppers plus a few Meadow Browns, Gatekeepers and one Red Admiral keen to spend time on the ragwort. After our hour we returned to the Estuary banks where there was at least one Painted Lady nectaring from the Sea Asters, plus a few Common Blues making our way past the last field.
We got together with the other spotters just after mid-day and it turned out that the morning was not a big success, with only about 5 Hairstreaks being seen. A couple were in the usual ‘glade’ and some good specimens had been seen at the ‘Limestone Ridge’ further down the reserve. In the glade there were a few nice Commas, plus one Brown Hairstreak briefly dropped down to the Blackthorn. Karen and I would venture out towards the Limestone Ridge later but the weather continued to cloud over and we returned home fairly early in the afternoon as I didn’t think the weather looked like it would improve. All in all, a slightly disappointing trip but only really due to the continuing ‘borderline’ weather conditions. Nikki had also mentioned that the first Brown Hairstreaks of the year had been flying at West Williamston in mid-July, very similar to sightings in Oxfordshire.

First view of the Estuary in good sunlight, before the first clouds of the day came over!

The path near the Estuary is full of Sea-Aster and Kelp (very easy to slip on..)

A Red Admiral was very attached to the Ragwort in the 'middle field' and would come back during every sun-break.

Plenty of Asters by the Estuary even if they were looking rain battered...

There was at least one Painted Lady enjoying the Asters.

One of the few Brown Hairstreaks on view - this one briefly coming down in the glade.

The Limestone Ridge had been more successful for the Hairstreaks earlier in the day, but not when we arrived..

By the Limestone Ridge there were at least a good selection of Wildflowers in view.
