for the most part carnivorous plant populations are not dominant enough to be dramatically significant, ecologically speaking, but there is an impressive variety of organisms that interact with various carnivorous plants in sundry relationships of kleptoparasitism, commensalism, and mutualism. for example, small insectivores such as tree frogs often exploit the supply of prey to be found in pitcher plants, and the frog "microhyla nepenthicola" actually specialises in such habitats. certain crab spiders such as "misumenops nepenthicola" live largely on the prey of "nepenthes", and other, less specialised, spiders may build webs where they trap insects attracted by the smell or appearance of the traps; some scavengers, detritivores, and also organisms that harvest or exploit those in turn, such as the mosquito "wyeomyia smithii" are largely or totally dependent on particular carnivorous plants. plants such as "roridula" species combine with specialised bugs ("pameridea roridulae") in benefiting from insects trapped on their leaves.
