Very beautiful pics, but:

#2 - Common bee

Nope. A(nother) hoverfly!

Like all other flies they have only two wings plus halteres, while wasps and bees have four wings.

#5 -Fly Lucilia sericata

It's any species of the large genus Lucilia, right ...

#6 -Common bee

Hoverfly, again!

By the way, there is no "common" bee or ant. There are several different species with specific names.

I suggest you to read my pinned post.

By the way, just recently I had a discussion with @barski who thought a hoverfly would be a drone of a western honey bee. It seems these hoverflies really know how to trick you! :)
