largest moth wingspan question

[daveuk]

Hi Dave,
Very kind of you to take a picture of your specimens measurements. Yes, it appears yours is right there in size with mine.

Another of our forum members Panacanthus has a specimen which he showed that measures 225 mm across the spread wings.

My specimen is from Morobe province, PNG. Perhaps, the nominate from Australia is larger (on average) than those from PNG.

You are welcome trehopr. My specimen is from Bulolo as many specimens were from PNG at that time.
It sounds like the larger specimens may come from Queensland. Have not seen any offered from there.
