Dandelion - Taraxacum officinale flower in reflected ultraviolet photography and simulated bee and butterfly vision II

Today more about that common spring flower, Dandelion - Taraxacum officinale in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating butterfly and bee vision. Just another specimen. Lens was a UV Nikkor 105mm quartz fluorite lens. Light source was sunlight. All shots were done at f8.

Also this different specimen of Dandelion flower has quite a prominent UV pattern, its petals are UV bright around 365nm, its center is UV dark, especially the anthers, and this gets quite nicely visible also in simulated bee and butterfly vision.

I have written about this flower HERE
 
Stay tuned, more will follow on that fascinating subject...

Dandelion and Daisy - Taraxacum officinale and Bellis perennis flower in reflected UV ultraviolet photography and simulated bee vision

Today shots of two early spring flowers, Bellis perennis - Common Daisy. and Dandelion - Taraxacum officinale in reflected ultraviolet photography. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f8 in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, as well as my XBV6 filter for simulated bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight.

This Dandelion flower has quite a prominent UV pattern, its petals are UV bright around 365nm, its center is UV dark, especially the anthers. Common Daisy, however has a bulls-eye UV pattern, its center is UV dark, and the petals are UV reflective around 380nm and both gets quite nicely visible side-a-side, also in simulated bee vision. Wouldn't it be interesting to find out, which flower is actually preferred by its pollinators, based on the very different reflection patterns in UV and BV?

I have written about the Dandelion flower previously HERE and about the Daisy flower HERE

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

Hawksbeard - Crepis in deep reflected ultraviolet photography, simulated butterfly and bee vision III

Today more shots of a different species of Hawksbeard - Crepis sp. in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter, my Jupiter-U and Saturn-U deeper UV filters, as well as my XBV filters for simulating butterfly and bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was a Xenon flash. All shots were done at about f8.
