Orange-tailed Clearwings are flying

I thought I would put the VES lure out in the garden again today. On previous occasions this month, it has attracted the Yellow-legged Clearwing, but today it was the turn of the Orange-tailed.
The lure went out at 1:15pm and the first individual arrived within a few minutes. Within 10 minutes, I had no less that 6 individuals, 5 entering the trap and one still flying about outside.

The orange tail stands out even in flight.
