Adrian Posted January 10, 2018 Share Posted January 10, 2018 Davies, A. (2017) Nepenthes x hookeriana Hort.Veitch ex Mast. (1881) (Nepenthaceae) Hooker's Pitcher Plant. Photographs in visible and ultraviolet light. Photograph of ultraviolet-induced visible fluorescence. http://www.ultraviol...le-uvr-and-uvf/ Comment:A lowland hybrid carnivorous Pitcher Plant (Nepenthes x hookeriana) in visible light, UVR and UVF. Note the different patterning on the interior of the pitcher.More research needed as to how the plant attracts its insect prey. (?both UV and fluorescence in moonlight?) Reference:https://en.wikipedia...3%97_hookeriana Technical specs:UVR: 105mm El Nikkor Lens, Full spectrum converted Nikon D300 camera, Baader U filter ("white balanced" using DIY PTFE scale), 2 x Metz 45 CT1 flashes with plastic window removed.UVF: Nikon D800 with 105mm micro-Nikkor. Conoy LED UV torch. 20 seconds @ f/16 Left-to-right: visible, ultraviolet, ultraviolet-induced visible fluorescence Link to comment
Hornblende Posted January 10, 2018 Share Posted January 10, 2018 More research needed as to how the plant attracts it's insect prey.Isn't nectar doing most of the job? Link to comment
Andy Perrin Posted January 10, 2018 Share Posted January 10, 2018 Great photos. I think we've seen a pitcher plant on here before - was that you also? Link to comment
Adrian Posted January 10, 2018 Author Share Posted January 10, 2018 Yes, insects are probably attracted primarily by the nectar, but also there is evidence that the fluorescence of the rim also helps (probably in moonlight).Yes Andy, the other pitcher plants were mine. I have been photographing them a lot over the last couple of years. Link to comment
Hornblende Posted January 10, 2018 Share Posted January 10, 2018 Pitcher plants are amazing! I have a N. ventrata, N. mirabilis var. globosa and a N. ampullaria, I will make a multispectral set :) Link to comment
