British butterflies, butterflies, butterflies of Sussex, Chalk hill blue, Chalkhill blue, Polyommatus coridon, Seaford Head Local Nature Reserve
This is the last of the seven new butterflies I saw during my seven days in Sussex and the second from my walk around Seaford Head (see yesterday’s blog for the first). This stunner used to be known as the Chalkhill blue and is now the Chalk hill blue – I haven’t been able to find out why the change was made but the name does indicate their preferred location, the grasslands found on the chalk hills and downs of southern England. (Its scientific name, Polyommatus coridon, hasn’t changed.)
Luckily, the two butterflies I saw were both males – I say luckily because the female looks an awful lot like a Brown argus / Common blue female, and we all know how tricky those are to distinguish.
Apparently, these stunning males are often seen in large numbers, many hundreds together, flying low over vegetation in search of females. What a glorious sight that would be!
Very pretty, particularly the Chalk Hill Blue (I also wonder about the name change. Maybe the pushed-into-one version was an error?)
Annie, I’ve a question for you… we have a sparrow here that I am fascinated by. As far as I know it’s a House Sparrow, but is an anomaly in that its normally black bib is a beautiful shade of mid-brown and is rather larger than its fellow sparrows. Have you seen anything like this before?

Not something I’ve seen, Val, but I know leucism can cause pigment changes in feathers, or it may be some kind of genetic mutation. I guess, just like humans and other creatures, odd sparrows can sometimes be born.

I’d not thought of leucism doing more than turning the feathers white on a blackbird or similar.
I’m thinking of having a ‘secret page’ on my blog with some birdie pics… if I do, I’ll put one there of ‘brown bibby’ as I call him and will let you know.
