Abstract

Carnivorous plants experience the same constraints as most predators, in that they must attract, capture, and consume prey. Natural populations of the yellow pitcher plant Sarracenia flava show most plants are composed of one to two ramets, with relatively few active leaves. An experiment was conducted to determine the effect of number of leaves on insect capture by creating spatially distinct S. flava groups of different sizes. Groups with more leaves attracted more prey, but prey capture per leaf was not correlated with group size. The per-leaf capture rate of different insect types, mostly wasps and bees, was also not correlated with group size. For this predator there was no advantage or disadvantage of foraging in groups.
