|Dark Green Fritillary on Creeping Thistle|
The stars this afternoon were 2 Dark Green Fritillaries, 3 Purple Hairstreaks and a cloud of mud-puddling Green-veined Whites. The Fritillary is not uncommon in N Wales (easily seen at Newborough, for example) but we only get odd ones on our transects (not even annually) and I don’t know where they come from. The Purple Hairstreaks inhabit the canopy of oaks, where egg-laying takes place, but they will come lower down to seek out honey-dew on ashes, or occasionally to take nectar from brambles. The mud-puddlers are male G-v Whites, seeking out salts (sodium etc) to replace those lost during mating. I’ve never seen such a cloud of white butterflies in Britain before, although it is a common sight in warmer places.
