The scent of lime blossom in the air
Hoverflies dancing everywhere
The lime blossom is short lived so get out there and give it a sniff, it really is the most beautiful scent. Plenty of lime trees in bloom around Edinburgh at the moment - there are whole streets that smell of lime blossoms not to mention patches of Colinton Dell, where you can smell the lime blossoms before you see the lime trees! (These are linden trees, not the lime trees that produce the citrus fruit).
The hoverfly in this case is, I think, a Myathropa florea, I'm waiting for confirmation on my identification from the UK Hoverflies Group.
