Purple hairstreak butterfly

I decided to take a stroll around the fields around the old cemetery area and council yard after work when i came across what i thought was a common blue butterfly sitting on umbellifer flower but after taking a closer look i could clearly see that it was not a common blue, in fact the underwing detail was something that i hadn't seen before so i took a few photo's and then encourage the butterfly to open its wings by encouraging it onto my finger. Once on my finger the wings opened to reveal a purple/blue patch on either wing, i instantly thought purple hairstreak but had my doubts as i thought you would only come across these in oak woodland, and as i've never seen one before was really happy to confirm the ID of a female purple hairstreak once i got home and also add a new species of butterfly to the llynfi valley list - Sorry Paul there has been 5 other records from 1999-2002 during a butterfly survey by Mike Clark. 1st one photographed though - nice [MHn]
Thanks for clearing that up Martyn (PT)

Nantyffyllon today.

      Bee beetle. Can't remember seeing this in the valley before. - 1st for valley, 6th for Glam. [MHn]
       Hoverfly sp. Flew before I could get another angle shot. - Xanthogramma pedissequum [MHn], the widening black streak between the eyes and extensive shading on the wing is enough to rule out Xanthogramma stackelbergi.

Nantyffyllon today.

                 This swarm of Honey bees were flying around the outside of
                 Nantyffyllon post office, preventing people from leaving this
                 morning. A bus passed, drawing them across the road and they
                 settled on this wall. They must have been guarding/following
                 a queen. As the wall was on a public pavement, the council
                 were called and a beekeeper from Bryn came and took them
                 away in a wicker basket.

Xanthogramma stackelbergi

Yet another hoverfly to add to our growing list of species for the valley Xanthogramma stackelbergi its recently been added to the british list in 2012 and closely resembles the more  common Xanthogramma pedissequum. I also think its a first for Glamorgan. The key features have all been checked and confirmed by expert Joan childs on the UK hoverflies website, i've posted photo's showing all the key features that were on the hoverfly below. The hoverfly was in long grass at the bottom of bramble at the old sewage works site at the old St john's colliery Cwmdu.

Xanthogramma stackelbergi
The dark wing does not extend down below R2 + 3
On this image you can clearly see that the  membrane between tergites and sternites segments 3 and 4 is clearly yellow which is consistant with this species on pedissequum you would expect to see dark shading on the membrane and you can just about see that the lateral edges of yellow bands slightly pinched on sides
Here you can clearly see that the yellow triangular spots are rounded to slightly pointed on the inner side.

The side of thorax usually has more than 3 spots but couldn't get a full side on view of the thorax to be 100% sure but there's enough evidence on the other key features to confirm ID.
