Very nice macro shots Michel. The butterfly is a faded Lycaena phlaeas. The day-flying moth below is Euclidia glyphica and I always find the latter very hard to approach. The Diptera on the Daisy is the Yellow Dung Fly - Scathophaga stercoraria, so I am guessing you have cattle nearby. The Damsel-fly seems to be Ischnura elegans. I have just started photographing Hoverflies and Diptera in earnest. I have some interesting images to share when I get time. I spent the weekend in a large forest and an unimproved meadow complex not far from my home. I know our member weymouthent is an expert on Hoverflies.
I was told the Lycaenidae was a female Lycaena tityrus ? We have a lot of Euclidia glyphica at the moment ... There are some cattle around but not so close ! I am really enjoying that new lens, but what I found difficult is to chose which picture to keep in my computer ?
