Scent organ of moth?

[sassy19a]

Hi there,

I took this interesting picture of two moths with one extending out its brush-like organ. Is that the male trying to release some pheromones to the female below before mating?

The dorsal view of the moth can be seen in my earlier post (http://butterflycircle.com/forums/showthread.php?t=8877)
