Good call on that one. If it becomes a pattern ------ then get them before they strike next time.

Dendrobium beetles destroyed 3 spikes of my Den. discolor this season. They didn't touch the remaining spikes after carbaryl was sprayed onto the remaining spikes.

Update

ES called it :bowing It definitely was thrips or at least some sort of other bud eating pest. After spraying down the entire plant with spinosad and giving the developing spike a squirt every week, I now have blooms :D

They are not the prettiest flowers. I suspected the thrip civilization got some damage in before their demise. But I am still very thankful and happy about these. They smell like bar soap. Just wonderful.

Additionally, the first spike which dropped all of its buds surprised me by developing another bud and bloomed as well :wtg:

Wonderful! Especially, enjoy their fragrance in the evening, when it is at its best. (turn the lights down low...)
