I have a B.liniflora plant that when it flowers...the flower is only there for 2 or 3 days and the next day I see the flower on the floor. I am not sure if it a pest because the rest of the byblis is fine. Even the flower stalk has no damage. Is there any reason for a flower to just fall off and I know it's not because it got pollinated..if that was the case the ovary would still be there and only the petals would have fallen.
