Not sure if this intergeneric hybrid is dimorphic. For the plants that are, male flowers don't last long, 2 weeks is actually quite good. (Then they start dumping pollinia that stick to the floor... and the flowers fade) If flowers get jostled they can loose pollinia and have life shortened. (I don't usually take them to orchid club meetings because transport always causes some of the pollinia to trigger causing flowers to fade prematurely) But in general, even for the ones that aren't dimorphic flowers don't last all that long. Enjoy and get your pictures while they are fresh. If it is a young or stressed plant, that can also cause flower life to be short... there is always next year.
Some of my Catasetinae are starting to lose leaves, but I'm still watering for another month at least. You can start cutting back the fertiiizer, though, if it looks like it is going dormant. (Blooming is no indication at all... they can bloom early season, late season, even after losing leaves)
