How do pitchers attract their prey?
« Thread Started on Sept 6, 2007, 12:22am » I know that they fall into the traps, but what attracts them to the plant, is it scent or the liquid inside?


Thanks. Stefan

Hi Stefan...

Actually as far as i know pitcher plants attract their prey with it's color, scent's, and nectar that the pitcher produce... the liquid inside the pitcher is for digestion usage...

The nectar give off it's own scent I expect but I'm sure some would produce their own scent, plus the smell of dead things inside can attract more bugs. Plus colours, sarracenia laucophylla is white for example, white seen in ultraviolet (what bugs see) is very bright purple and a very attractive colour for them. « Last Edit: Sept 6, 2007, 12:44am by zakhren »Link to Post - Back to Top 60.49.32.184 stefan

« Reply #6 on Sept 7, 2007, 2:05pm » That make sense Cindy, since the insect have to be at the peristome if the plant wants to trap it. If it attracts the insect to other parts of the pitcher, the trap/pitcher would not be as effective to trap insects.

Thanks Zak, now I know why my D. filiformis captures more insects than my burmanii or other drosera under my grow lights. The filiformis has green leaves but white/clear tentacles and dews whereas my burmanii has red tentacles (which made the dews look redish).

The peristome is very effective. I saw a video on how ants slip into pitcher because the peristome is moist.
