Hoverfly on Liatris

Choice between a pic with a good hoverfly and one where the flower is better.
Warmer again the last couple of days (won't last) and managed to get a sizeable section of the garden tidied this afternoon.
We don't have cable anything but next door do and the cable goes through our garden. That's no trouble until the cable people come when we're out and dig up plants and move things. This time it was moving a compost bin and digging a hole, I had to re-site the bin and reload the compost and generally tidy up - grrr!
