Hi - this is a very unusual record. It is of a male Tau Emerald attempting to mate with a female Swamp Tigertail. Completely different families. I'm not sure how to classify this. Perhaps if I put this record down under Tau Emerald, and you submit a repeat record that I'll put under Swamp Tigertail.

Wow! Thanks Harvey. I have submitted a duplicate record as Synthemis eustalacta (Swamp Tigertail)

At Rugosa we try not to be too judgmental, but this is certainly different. The two insects were creating a great deal of fuss, suggesting that affirmative consent might not have been forthcoming. On the other hand, I have no idea what the accepted mating ritual is for a Tau Emerald.

And the male hindwings are a bit battered. I'm impressed that he could fly at all.
