Cretian Rock Tulip - Tulipa saxatilis with crab spider in reflected ultraviolet photography and simulated bee vision

Today shots of a Cretian Rock Tulip - Tulipa saxatilis with a crab spider sitting in it, just having its lunch, in reflected ultraviolet photography, using my "work horse" UV filter, the Baader-U filter, as well as my XBV6 filter for simulated bee vision. Lens was a CERCO 94mm quartz fluorite lens. Light source was sunlight. All shots were done at about f5.6.

Triptych of human vision, UV and simulated bee vision (left to right):

This tulip has a rather subtle UV pattern, tricky with inside UV reflective petals, which reflect UV rather well around 380nm using a very shiny petal surface and quite classic, an UV dark center creating a bullseye pattern. Surpisingly the spider also appears quite well in UV and has UV bright spots on it - maybe to attract its prey? Only nature knows...

I have written about this Tulip previously HERE and about the crab spider HERE

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