hoverfly

In my garden I see the last weeks, lost of hoverflies..(zweefvliegen)
they can kind of stand still in the air...like a colibri.
This one is a Marmalade hover-fly...
in dutch he is called a pyama zweefvlieg..or (latin name:Episyrphus balteatus)
as if he is still wearing his striped pyjama..and did-not change clothes after breakfast.
