[UV] Rudbeckia hirta

Today I found another nice Rudbeckia species (Rudbeckia hirta that is), which sports some interesting UV pattern.

[click on images to see larger ones]

Standardized reflected false UV "colors" according to the previously described "UV color palette" related to wavelength.

The normal intensity palette:


and this is the high intensity palette:


So here now the UV image of that flower:


So from that yellow UV color we may deduct that this flower UV reflection is from around 360nm.

And here the UV image of another flower and two young ones:

which shows quite different UV reflections (360nm region = yellow, but in the 385nm region = violet which the young ones exhibit)

For comparison here the VIS shot:

which shows quite different UV reflections (360nm region = yellow, but in the 385nm


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