Hi,

Can you tell us the size of these bees and when and where you made this picture? Is the beginning of the abdomen of the male reddish?

Theo Peeters tells it looks like Lasioglossum spec. With a little more information he may be able to tell the species name.

Hi Jan Willem,
The animals were tiny, I never thought they were bees when I first spotted them, that small! Can you see the hairs on the leaves?

The picture was taken yesterday in Rotterdam.

What details can help? I took more pictures because it is very hard to get both male and female in focus at the same time.

I cannot realy see any reddish parts of any significant size.

Here is another view:

and the wings:

The photo shows to bees of the genus Lasioglossum (Halticinae). Normally, a species recognition by foto is difficult or impossible, but in this case it may be a Lasioglossum sexcinctus (or a closely related species). A special character are the dense apical bands on terga, which are uncommon in Lasioglossum. But this identification is only an idea, and not a 100% identification.
