Orange coneflower - Rudbeckia fulgida in high resolution reflected ultraviolet photography and simulated bee vision IV

Today high resolution macro shots of that decorative flower Orange coneflower - Rudbeckia fulgida var deamii in reflected ultraviolet using Baader-U filter and in simulated bee vision using my XBV6 filter. Lens used was a 60's older 40mm Dialyte lens. Light source was Xenon flash. All shots were done at about f11.

This attractive flower in macro close up even more so shows its very specific UV pattern, its petals have a UV dark pattern, invisible to us humans. It also shows the conical cell structures that enable insects to have a better grip on the surface when landed, and all this gets nicely visible.

I have written about this flower HERE.

Stay tuned, more will follow on that fascinating subject...
