Kathy,
No, I did not treat my collection with a pesticide -- I did treat one orchid
for a mealybug earlier this year, but that was a single bug and a single
plant (not this one). Besides it could not be sudden death because I am not
capable of killing orchids, though I can easily kill other houseplants. ;-)

Unless you have recently treated your collection with some sort of a
pesticide, in which case red leaves = sudden death.
