Something eating flower stalks?

[lzel924]

I cannot tell if something is eating my flower stalks, and if so what it could be. The flower stalks either stop growing halfway, look eaten at the end, or never bloom and look sick. This has happened on at least 5 Phalenopsis orchids mounted on trees. I included a photo of what I THINK might be a Cuban tree frog who likes to hang out between the leaves, but I can't find any readings that he would be the one eating my orchids.
