Bombyliidae and Butterflies

We are very lucky to be having a spell of gorgeous weather and the garden was awoken! Several Bombyliidae around the flowers today and a few butterflies (extras) too.
This shot was 1/5000th second, these guys really vibrate!
One positive aspect of people staying at home is the lack of traffic noise and therefore the clarity of the bird song. And maybe the birds can sense a difference in the air and are singing more to each other too, who knows!
