Flowers were photographed near Bensheim, Germany, 9 June 2013.

 

All images were taken with a broadband-modified Panasonic Lumix G1 and the EL-Nikkor 80mm/f5.6 at f8-11.

UV-image, Baader U-filter 2”, ISO 400, sunlight

These flowers are quite UV-reflective with UV-dark veins. Pollinators include bumblebees.

“Simulated Bee Colours”: This is a composite image of the greyscale converted UV image (-> blue), the vislble blue (-> green), and visible green (-> red) channels. The goal of this is to mimic the spectrum that bees and other insect-pollinators can see.

My captures of V. sepium confirm your findings. In due time I will open another thread to how the epidermal cell structure of the corolla. But has to have lower priority as you have already posted an introduction on this species and there are still a massive backlog of material to process.

Good to know, that we have comparable findings in this species! - I'll also try to put as many new species in the database as possible. Maybe it's a good idea to just add a brief comment, as you did, if one has captured a similar or identical UV signature of a given species.

That is a good idea. I shall keep it in mind.
