I think they are eggs of something. I can't remember what it is, but there is something that lays it's eggs on stalks like that to keep them out the way of other pests. Hopefully someone else knows what it is that lays them like that.
I think you are right Rosie! I'm really glad I don't have an orchid killing bug or fungus! I will leave them alone. I haven't been plagued with any kind of pests so hopefully these beneficial buggies will find something to eat, or not? Yeah, not will be better!
