moths in pitcher plants

[Zachary Lemann]

A friend of mine found a small moth (I have not seen it yet) on the inner
wall of a pitcher plant leaf.  Obviously, this thing could hold on, but I am
wondering if anyone out there is aware of a moth species that is a pitcher
plant symbiont?  For what it's worth, this animal is described as having a
wingspan about the size of a man's thumbnail, and at rest the proximal part
of the forewings is a striking yellow, and about halfway down their length
this changes to jet black extending to the outermost edges of the forewings.
