Two Moths Mating (Amata huebneri)

Amata huebneri, commonly known as the wasp moth or tiger moth, is a species of flying moth that is a member of the subfamily Actiinae. Unlike most moths in the family Erebidae, which are nocturnal creatures, this one is more active during the day, and it also flies fairly slowly.

Amata huebneri has a proboscis that works similarly to a butterfly's to sip nectar from flowers. Almost every country in Southeast Asia is inhabited by this species.

I recently caught two moths that were mating.

Copulation occurs when the ends of the male and female posterior abdomens meet, as is the case with the majority of moths, in the opposite direction.

Perhaps some insect species have easily distinguishable male and female members based on size, with males often being smaller than females. But with Amata huebneri, it's a bit hard for me to tell which one is male and which one is female.
