These Opuntia flowers have a unique UV reflection, In UV the petals have inside a metallic like shine that reflects UV strongly, maybe to attract pollinators. otherwise there is no distinctive UV pattern, and all this gets nicely visible, also in simulated bee and butterfly vision.
I have written about that flower before HERE
Stay tuned, more will follow on that fascinating subject...
