Big vs small
I spotted this moth last week. Not this one but its brother (or sister?). This morning I saw it again. The interesting feature is the translucent membrane and if you observe the detail you will see a thin line in the middle of membrane.
Another interesting thing is I just realized that a small moth standing to it. I just realized when editing the photo. If the size of the big moth is around 20 cm (length), could you imagine the size of the small one?
