Comment:
Photographs taken in the order of visible light, ultraviolet, and simulated insect vision. To distinguish between UV shadow and UV darkness, I usually "dissect" deep-corolla flowers like this so that there is no question of possible shadows. This is a male specimen. Simulated insect vision shows the UV-dark areas as green, with the anther a much deeper green compared to the interior of the corrolla; because under UV, the anther is almost totally UV-black.

(My original post to this thread seems to be missing. Perhaps I did not hit the Submit button properly?? I will start over.)

I love this Pumpkin flower. It is unusual and different - and very interesting. Thanks for posting this one!!

It would be cool to see more vegetable flower fotos here on UVP. If we get enough, then perhaps I can create a section for them.

I've also used that 'dissection' technique to show what is going on inside a tubular flower. The bees see that when they go inside the flower, but we usually do not. ;)
