Photosimulacrum

Lately there have been many articles on plant responses to external stimuli such as specific insects, or mimicry of beneficial insects, which raises many questions such as how exactly does an organism without eyes visually mimic anything else?

The answer would seem to be in the negative spaces, in other words, in the absence of light or at least certain partially obscured wavelengths of light which would allow the cells of a photosynthetic being to interact with external objects.

Today, (and this may be entirely coincidental), I noticed that all of the farthest newest smaller flower-clusters on the south-facing sides of all of a restaurant's outdoor patio planters were casting shadows that mimicked the shape of flittering bees upon the side of the planters they were housed in.
None of the larger varieties of flowers cast an insect-like shadow but the end-growths of all of the smaller varieties like Alyssum and Lobelia had arranged themselves to cast randomly moving bee-like shadows, and the actual bees that I saw around them tended to close in and mimic the waggle of this shadowy-bee before checking out the rest of the bouquet.

Might be something, or it might not be anything at all... I can't even think up any idea to go with it other than as an hypothesis to an experiment.

Check it out. See if you notice the same effect with tiny south-facing flowers in your area.

Cheers.
