Three of Two - _TNY_3662
The Idas blue (Plebejus idas) and silver-studded blue (Plebejus argus) are two *very* similar butterflies. So similar that most of the times I can't distinguish between them.
This beautiful trio on a couple of tansies (Tanacetum vulgare) at Åva-Stensjödal in Tyresta National park is either P. argus or P. idas,but we wount get further.
The wing-colouration can however tell us that the one on the right is a male and the other two are females.
