Thanks for the kind words, everyone! It's certainly not a top-tier roth, but I'm quite pleased. I'll put up some new pics when all the flowers are open.
It is believed the staminode shield which is elongated and covered in hairs mimics a colony of aphids on a plant stem. Syrphid flies, whose larvae eat aphids, lay their eggs on the stam. shield and then fall into the pouch. I'm sure you're familiar with what happens after that.
