Greenpower butterfly exhibit, Kowloon Park, Hong Kong II

Today more about an organization in Hong Kong, GREENPOWER a charitable institution, which I have supported with my images for an exhibit at Kowloon Park about butterflies. Aside from other environmental issues, they are concerned about Butterflies and would showed children their beauty and importance, but also that they have abilities, we humans don't have, like being able to see ultraviolet light.

Here showing the original images which have been used, a Rudbeckia hirta flower, in a Quadriptych of human vision, UV, and simulated butterfly and bee vision (left to right, top to bottom):
 

This flower shows a very prominent UV bullseye pattern, as its petal tips 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 bee and butterfly vision.

And here now a few images of that exhibit which I have gotten from the organizers.





I have previously written about butterfly vision HERE

I'm very happy to hear that the exhibit was successful and my kids had learned a bit more about butterflies and their unique abilities!

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

Exhibit at Museum Mensch und Natur, Nymphenburg Palace, Munich, Bavaria Germany

Today about a German Museum, Mensch und Natur ("Human and Nature") located in the famous Nymphenburg Palace in Munich, Bavaria, Germany which I support with my images for a forthcoming exhibit about insects named "Knallbunt und unsichtbar" ("extremely colorful and invisible") which will be shown July 6 - November 4, 2018. It will include works of mine about (simulated) butterfly and bee vision.

Here showing some of the images which will be on display, a Gazania rigens flower, in a Quadriptych of human vision, UV, and simulated bee and butterfly vision (left to right, top to bottom):

 

This flowers outer petals reflect UV around 365nm, whereas the inner parts are quite darker, hence forming UV nectar guides for UV seeing insects. There are also highly UV reflecting marks inside around a dark UV center, all invisible to us humans but clearly visible to bees and butterflies, and all this gets nicely visible here, especially in simulated bee and butterfly vision.

I'm wishing the museum and its visitors a successful exhibit, certainly worth going to with family and friends!

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

Opuntia humifusa in reflected ultraviolet photography and simulated bee and butterfly vision

Today shots of a decorative plant, a Prickly pear - Opuntia humifusa in reflected ultraviolet photography using my "work horse" UV filter, the Baader-U filter as well as my XBV filters for simulating bee and butterfly vision. Lens was a UV-Nikkor 105mm quartz fluorite lens. Light source was sunlight.

Quadriptych of human vision, UV, simulated butterfly and bee vision (left to right, top to bottom):
 

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...
