Well, almost white. Still from the same location I posted about here and here, at a small field of thistles.
I think this one is a small white (Pieris rapae), klein koolwitje in Dutch:
Olympus Stylus 1s, 300mm, ISO160, f5.6, 1/500s
A holly blue (Celastrina argiolus), boomblauwtje in Dutch:
Olympus Stylus 1s, 300mm, ISO160, f5.6, 1/500s
Thanks for watching!
