first order of business:
go here
Orchid Photo Identification Guide
and see if you find something that looks like your plant. we need to know what type it is first.
on the wild chance that it's a Dtps. Black Butterfly, go here
http://aos.org/aos/orchids/page01.aspx
and download the care sheet for a phalaenopsis.
post a pic of it if you can and we will gladly pontificate on its care.
