Their dance is quite enigmatic, bouncing up and down for upto an hour after dusk.
The Male gives to the name 'Ghost Moth' as he is pure white, almost translucent, whereas the Female is yellow marked with orange, both very colourful in their own way.
Last night I was blessed with my first Female to the trap (apparently they are less frequent at light) generally they are less frequent altogether in my Garden as i've only recorded one Male this year so far aswell.
Here they are for your viewing pleasure.
Ghost Moth - Male (Ghostly eh!)
