The story on this critter is that the male sings for a couple of hours to
get the female in the mood. Once she's in the mood, he deposits the stuff
you see in the picture on her. Then, he's got to sing for another 45 minutes
or so to get the female to take in his deposit. If he doesn't, or if she
doesn't like the song, she ditches the deposit and goes looking for another mate.
