Activity Around the Trigger Plant!

 

A small winged insect hovering around the bloom of Stylidium debile AKA Fragile Trigger Plant


    I was tending to some carnivorous plants when I noticed, a tiny winged insect flying around the bloom of a Stylidium debile (AKA Fragile Trigger Plant).  That's the plant in my post from April 30, 2025 (click to see post), where the reproductive column "smacks" an insect when it is triggered, transferring pollen to the insect as part of the reproduction process.  I watched as the tiny winged insect landed in the middle of the bloom and triggered the reproductive column!  It was fun to watch and it looked like the column gave the insect a 'one arm hug'! It held for a few seconds and the insect didn't seem to be bothered by the action.  Oh I wished I had my camera with a close-up lens to capture that moment.

After a minute or two, the column reset and the insect returned to enjoy the bloom, but it didn't trigger.  After some observation I learned that after resetting, there is about a 15 minute window before the column smacks again.  The picture below is with my iPhone and after the insect got "smacked".
