Jack-in-the-Pulpit - Arisaema triphyllum in reflected ultraviolet photography and simulated bee vision

Today shots of some decorative autumn flower beeries Jack-in-the-Pulpit - Arisaema triphyllum in reflected ultraviolet using Baader-U filter and in simulated bee vision using my XBV6 filter. Lens was a 55mm Dialyte lens. Light source was sunlight. All shots were done at about f8.

This attractive but poisonous flower seed has no specific UV pattern, no wonder actually, since there is no biological sense behind it to attract bees, but very decorative in fiercy red and all this gets nicely visible.


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