[V, UV, BV, FL] Aster

A few Aster hybride shots, which has no noticeable UV patterns, as expected though.

Visible light shot using Baader UV/IR Cut filter and Xenon flash


UV (ultraviolet light) shot using Baader U-filter and Xenon flash


BV (simulated butterfly vision) shot using XBV2 filter and Xenon flash


FL (UV induced visible flouorescence) shot using Nichia 365nm UV LED and Baader UV/IR Cut filter in front of the lens

So, Klaus, is it reasonable to infer that to the pollinating insects, there is no diversion of interest to the general foliage as it's invisible in UV light? Or does the visible light really make them as important.

Of course, they detect the nectar molecules in the air, but for visual clues it would be neat if almost everything else was removed from their view.

That hybride flower is infertile as it has no stamens or any other "sex organs" anymore, so I woudl not use this example to generalize. (You have edited into my posting ... ehemmm)

I didn't mean to edit by just showing two pictures, rather the visible light v. the UV. Just wondering about signals in UV to insects where the flower is fertile. IOW, what advantages are there in the investment on sensors to pick up UV light?
