Albulina orbitulus - Alpine Blue - Alpenblauwtje - Heller Alpenbläuling
The male upperside ranges from a deep, shining skyblue to a greyish or steely blue, and is unmarked apart from the narrow black borders. The female is brown, often with a slight blue dusting at the base. Both sexes have clear white fringes, with brownish-grey, rather hairy undersides that are often tinged with green. There is usually an arc of small, black post-discal spots under the forewing, although these are sometimes absent. The spots under the hindwing are pure white with no black centres and are very conspicuous. Flight from June to August. The major larval foodplants are milk-vetches, especially Alpine Milk-vetch.
