Anyone know what it could be causing this?

[Phallgirl]

I have what is suppose to be a Phal Pantherina and it has a spike with forming buds. When one starts to come out it turns brown and dies. Only the bud dies. Anyone know what sort of bug/disease this could be??? I saw a silver colored bug in the bark with my magnifying glass, could that be the culprit? I noticed a tiny bite like mark on the spike distal to the buds forming too. It's really frustrating as you all know-----waiting for a spike then having some bug eat them !!!! The leaves and spike are healthy looking.
