This flower shows a very prominent UV bullseye pattern, as its petals are very UV bright (around 365nm) to about the middle and its center is very UV dark, and all this gets nicely visible also in simulated butterfly and bee vision.
I have previously written about that flower HERE
Stay tuned, more will follow on that fascinating subject...
