Well, now I feel silly. I got all excited because our Darwin's Orchid bloomed. But with further research, I discovered that our orchid is actually another species that is closely related to Darwin's Orchid. Ours is an Angraecum eburneum, and the orchid that prompted Darwin to make his famous moth prediction was an Angraecum sesquipedale. Sheesh!
Same genus, though, and both are native to Madagascar, and both have that elongated nectary spur.
I feel a lot better now that I've cleared that up.
Anyway, I still feel that an exceptionally long proboscis would be necessary for any moth to get it's way with our Angraecum eburneum.
