Little Black Dress - _TNY_0018

Bees in the Hylaeus genus are known as masked bees or yellow-faced bees - but since this one on a thistle at Åva-Stensjödal in Tyresta National Park, Sweden is a female, she's not sporting a yellow face-mask, but go for the all black look - which means ID stops at Hylaeus sp. for this one.
