Gazania - how she does it (butterfly vision simulated)

Already last year I showed some images of a south african Gazania flower. I was wondering how she attracts insects, so I used my bee / butterfly vision filter and took some shots. Here the astonishing results.

Well, I guess now we know what she "does", the pollen lights up strongly around the flower petals in the central part. They have a quite strong UV reflectance also, so like a concentrated ray of light shoots out of that flower to attract insects!


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