E. cicutarium is an herb native to the Mediterranean area but grows also in central Europe where the climate is appropriate (mild).

 

Flowers were photographed near Bensheim, Germany 24 May 2013.

 

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

“simulated bee-colours”: composite image of the UV image (-> blue) (grayscale conversion) and the blue (-> green) and green (-> red) channel of the visible light image. The goal of this is to mimic the spectrum that bees and other insect-pollinators can see.

The petals have a quite strong UV-reflexion while the stamina are UV-dark. From the channels used for the bee-colours, UV and blue are most dominant which creates the bee-turquois.
