Chalkhill Blues are, to me, redolent of sunny warm skies. We are lucky here on the Surrey chalk downs that in a good year the slopes can shimmer with milky-blue as thousands dance above the sward - but not this year. They seem to be in depressed numbers. The downland flora has been rather compromised this summer, with the dry and warm March, April and May ensuring that little flowered and left behind stunted and dried up blooms. The Chalkhill Blue food plant, Horseshoe Vetch, can carpet large areas of the slope at Denbies Hillside, but on my visits this summer it has been in short supply. This is where today's photograph was taken.
Talking of the weather, The Hairy Birder blog mentioned his dissatisfaction with the online weather forecasts, and how they vary. I have noticed this as well. I check three sources - Met Office (often wrong), BBC (correct more often than not) and XC Weather (not bad but always over-estimating wind strength). How three sources, using similar, expensive equipment, can be so different is beyond me. Perhaps the BBC hang more sea-weed out of the office windows...
