Thanks..was surprised how large it is. Females must be really enormous.

Male specimen from Viet-Nam

Four Irish specimens where the white ground colour is replaced with yellow (form sulphurea)
Males on left bred in 1982. Females on right pre WW2. Wild caught.

It's a really great species. I have some old Indian specimens but not quite the quality of your specimen.

Lovely specimens. Don't usually see them in this condition.
