A plant?

I chased a limoncella butterfly (I prefer the italian name) passing with its erratic flight, designed with long evolutionary fine tuning to make it difficult for predators (and photographers) to catch them. It moved between flowers in the meadow, but it was quick and never stopped long enough on any flower for me to be able to get in position for a good shot. Then it disappeared in the vegetation. When I finally found it, it was positioned on a low plant making it almost invisible. I was impressed by its posture and camouflage intuition. For a moment I asked myself is it a plant or a butterfly?
