How do you tell a male Luna moth from a female Luna moth?

Answer:

Answer

Look at the antenna on the head. If it's a male it will have large well developed antenna with lots of hairs on them to catch a whiff of the female pheromone. The female antenna would be plain whip like.

I would describe the female antenna is much narrower than the male antenna, but still rather feather-like in appearance.
