but in that case it would be slippery even when the pitcher peristome isn't wet. based on that video we can see that the peristome itself isn't enough to slip the insects into their doom.

wow! thanks for sharing the info Dave. I found a video on this....I posted it in the video section. Here's the direct link: www.newscientist.com/channel/life/mg19826591.600-gotcha-flesheating-plants-set-a-wily-trap.htmlActually thinking about this kind of makes me wonder the purpose of the peristome is is in most cases ridged or toothed rather than just a flat surface. The small ridges fuction to form a slippery plane when faced with the surface tension of water which stretches out over the teeth of the peristome.

New Scientist observation on the pitcher plant trapping mechanism which involves water aquaplaning on the peristome. {Thanks for the topic in the main forum Dave . Found this as I was searching for more info }

Fantastic pics Joel. Yeah....Pk is right... I am recently facing few premature pitcher openings as well. THis is becos my humidity is typically between 60 - 90 day - night. But at dawn....humidity goes down to 50's. As a result...lowii which is otherwise thriving opens its pitchers prematurely.

I understand what you go through. I live in ontario canada where summer temps can be almost like intermediate/pure lowlander ranges. Day temps can go to 90F. However, winters can be insanely cold. So yeah...I have to resort to indoor growing...a balancing act with lighting such that the heat doesn't exceed the comfort ranges of my plants. Luckily..... it seems basements are the best place to grow my plants and thats where i am growing them right now.
