Hi Connie:
It was nice to see you at the orchid society meeting yesterday : -)
Here 's a link to the article I read:
Pleurothallis pterophora
Forgive me if I entered the link incorrectly.
I bought the same species from the same society member last year. It lasted for months looking fine, then early this year it began to drop one leaf a week until all gone. I have no idea what went wrong, no idea how to fix it. That was my second try, so I'll be moving along to other sturdier species.
Best of luck with yours!
