I really don't believe that's ethical. Venus flytraps are a vulnerable, almost endangered species. They are part of a monotypic genus, Dionaea, so they have no close relatives that are REALLY like them. (Even Aldrovanda has its differences.) They grow naturally exclusively in the bogs of North and South Carolina, and their habitats are rapidly being destroyed. A single plant could divide every couple of years and produce many seeds each year, which, being in their natural habitat, would very likely germinate and produce new plants. To top all that off, it's not just happening to the flytraps. Many carnivorous plant genera, particularly Nepenthes, have vulnerable, endangered, and critically endangered species that stand no change against the might and will of man. The only reason they're still around is that people finally have opened their eyes and started working to keep them alive. The genus Aldrovanda is chock-full of extinct taxa, a seventeen out of eighteen, in fact, and poor Aldrovanda vesiculosa, the last of its kind, is a vulnerable species. The Venus flytraps are disappearing, and you, if you hypothetically took a plant from the wild, would probably kill it from the shock of being uprooted anyway.
All in all, I'm not for poaching plants.
