The Chalk Hill Blue Butterfly.
The earliest I have observed this species previously was the 12th of July.
This year I found one or two on the 10th at the normal place I would expect to find them.
So its early days yet and perhaps another 7 to 10 days before numbers in some strength emerge.
This species is normally only found in Southern England, but we are fortunate in Northern part of East Anglia of having a very specific local location with all the correct habitat that this very pretty butterfly exists.
