Settling in for the night / Поселение на ночь

This holly blue (Голубянка весенняя, Celastrina argiolus) I saw the other evening has found a comfortable place:

^{Olympus Stylus 1s, 200mm, ISO200, f8, 1/250s}

These little butterflies are called boomblauwtje ("small tree blue") in Dutch. They like to sit in trees, and the top side of their wings, which they rarely show, is blue:

^{Olympus XZ-1, 112mm, ISO100, f8, 1/400s}

From the side, they look silvery in full light, with a hint of blue and sometimes pink:

^{Olympus XZ-1, 112mm, ISO100, f8, 1/250s}

Every now and again, they descend from the trees to look for minerals on the forest floor:

^{Olympus XZ-1, 112mm, ISO100, f8, 1/100s}

They usually get their minerals from bird droppings:

^{Olympus XZ-1, 112mm, ISO100, f5.6, 1/160s}

Pretty little butterflies, despite their diet.
