The Little Brown Job!

I had two e-mails over the weekend, one included an image of a wader. I was amazed at how time flies when I discovered it was 6 years ago since I found a Wood Sandpiper on Conder Pool 10 August 2014.  

The second message was the reminder of a butterfly found 11 August 2018. The last time I had seen the author of the e-mail was at Glasson Dock when together we found 9 gulls all ringed, including 5 Common Gulls, a species I had never found ringed before. 

Brown Hairstreak at Gait Barrows.

Given that the Brown Hairstreak has a localised distribution almost entirely in Southern England, the South Midlands, and South Wales, with the nearest colonies in East Worcestershire some 150 miles away, the obvious question is; how did it get to Gait Barrows in Lancashire. There are three possible explanations: 1) This elusive and largely arboreal butterfly could have been ever present, but was simply overlooked or mistaken for the widespread Purple Hairstreak. 2) Brown Hairstreak eggs were inadvertently brought in by local landowners when Blackthorn from nurseries outside the area was planted in the vicinity. 3) An unauthorised release of a small number of adults, or late stage caterpillars. The latter option for the reappearance of Brown Hairstreak in North Lancashire was favoured by three experts in the field.

I'm hoping to make a break to freedom tomorrow and I think I know where I'm going.

In the garden.


A Small White, Red Admiral, and Speckled Wood. It was also good to see a young Robin and Greenfinch in the garden.

Not sure when you said "I think I know where I'm going", Pete, if you meant in the garden, Conder Pool, or Gait Barrows - I suspect the latter. If so, I'm looking forward to hearing how you got on - I have never seen a Brown Hairstreak.

Keep safe. Best wishes to you and KT - - - Richard
