This is very true about Alophia species, which are in the Tigridia tribe. Alophia flowers are only open for a few hours, then they twist up and drop off. Fortunately for me, most flowers end up pollinated so I do get seeds.

As you know, many irids open in the morning and close by mid day. If you went to work each day on a normal shift, you might never see them open. Just a crazy theory, you probably are aware of this (since you have seen it blooming for you in the past) and have looked at the right time.
