It would be interesting to see 8 am/12/5/9 pm fragrances to see if it’s pollinator specific.FWIW - I smelled 15 thaianums (from different sources) at 8:15am this morning and only 2 of the 15 were fragrant. Will try again in a couple of hours to see if anything changed.
Neofinetias are strongest at dawn and sunset. Their white flowers attract the nocturnal moths with long probosis to reach the nectar at the end of their spurs.
