The earlier pictures were taken on my wee compact Canon ixus 970IS, which involved sneaking up on the butterflies. This can be very frustrating when they fly off, but very rewarding when they don't!

Since 2012 I have been using a Panasonic Lumix FZ150, which allows me to zoom in to the butterflies from a couple of metres away.

Wall Brown - Lasiommata megera

When I had been down in the Borders looking at the Small Blues I briefly saw a couple of Wall Brown butterflies, Lasiommata megera. It struck me that the area was very similar to a section of the coastal path in East Lothian and as I heard that Wall Browns had been extending their range northwards I thought I should have a look at an area near Bilsdean.
I was involved with the construction of this section of the coastal path, called the John Muir Way, so I knew it well and also knew that I had never seen Wall Browns there before.
In June 2010 I went to Bilsdean one lunch hour and walked along the path and very soon a small butterfly flew up and over my head. When it landed I was delighted to see it was a Wall Brown!

This is a female ...

... and this is a male.
I saw five that day and returned later in the year to find that they had obviously bred and produced a second generation. As far as I am aware, the only other record of a Wall Brown in East Lothian was one that was seen in 2005. These, though are breeding and established in East Lothian.

I returned in 2011 and was pleased to see good numbers and that they have moved slightly further up the coast. In fact I also saw one about 20 miles up the coast and heard a report that they had been seen in John Muir Country Park about 30 miles from the original site, so I think that they are well and truly established here now.

  1. What a beautiful little guy! So encouraging to read your accounts and know that so many species are spreading. I worry that the opposite might be happening here, with all the pollution, etc.
