Hi David, its a very distiinctive caterpillar and has the wrong colouration for the Emperor. A mature green Emperor doesnt have the white and yellow markings of BYU. I had to save and zoom in on the image to be sure of the markings. But yes at first glance Emperor did seem to be the likeliest candidate. A 3cm Emperor wouldnt show any green yet, just black and yellow.

Hi Flinty, Beautiful Yellow

Hi Flinty,

Beautiful Yellow Underwing is probably of more note in most locations, adult emperor is undoubtedly a more impressive moth, April and early May is the time to see it, the males are on the wing particularly on hot days but they usually require a butterfly net to intercept them in flight, in my experience they simply will not rest to be viewed.
