Creeping Zinnia - UV pattern when "bee ready"?

I noticed that on a Creeping Zinnia young flowers (in front) do not show a prominent UV pattern, but others do (the one in the back), which are ready for pollination.

I wonder if that UV pattern would disappear when pollination has successfully happened? I guess that would be worth some scientific study (or maybe I should do it?)... 

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